I um, I want to 21 00:01:18,720 --> 00:01:22,800 Speaker 1: be respectful. Well, yeah, a long time fan first Time 22 00:01:22,880 --> 00:01:25,560 Speaker 1: co host. Well that hopefully that that you know, that 23 00:01:25,600 --> 00:01:28,040 Speaker 1: will translate to this that you know that you have 24 00:01:28,080 --> 00:01:31,280 Speaker 1: an enthusiasm for not just the topics, but for stuff 25 00:01:31,319 --> 00:01:33,200 Speaker 1: you should know in general. You know, like that'll I'm 26 00:01:33,200 --> 00:01:35,319 Speaker 1: sure people will appreciate that. I know this is a 27 00:01:35,319 --> 00:01:38,720 Speaker 1: little odd. This is it was quick, it was sudden. 28 00:01:39,000 --> 00:01:41,520 Speaker 1: He is out of the blue. But hats off to 29 00:01:41,560 --> 00:01:43,640 Speaker 1: you man for stepping in like you you're a braver 30 00:01:43,760 --> 00:01:46,039 Speaker 1: soul than I am. Ah. Yeah, I'll be honest with you. 31 00:01:46,080 --> 00:01:48,600 Speaker 1: I'm a little scared. You're doing good. What Aaron Cooper 32 00:01:48,680 --> 00:01:52,400 Speaker 1: is gonna think everybody else is is gonna do. But 33 00:01:52,800 --> 00:01:54,720 Speaker 1: I think Aaron Cooper is the least of your worries 34 00:01:55,280 --> 00:01:59,840 Speaker 1: probably the show. So well with that, let's go on 35 00:02:00,040 --> 00:02:03,440 Speaker 1: with the show. We're talking today about three D printers. 36 00:02:04,160 --> 00:02:09,960 Speaker 1: Are you pretty familiar with three D printers? So I 37 00:02:09,960 --> 00:02:12,520 Speaker 1: I am as well kind of you know, mostly just 38 00:02:12,560 --> 00:02:15,880 Speaker 1: from keeping up with like the big news stories, um, 39 00:02:15,919 --> 00:02:18,280 Speaker 1: but the ins and out the details of a three 40 00:02:18,400 --> 00:02:21,919 Speaker 1: D printer, um, the machine itself, how it operates. I 41 00:02:21,960 --> 00:02:24,960 Speaker 1: didn't really know a lot about until I read this article, Like, 42 00:02:25,000 --> 00:02:31,400 Speaker 1: were you familiar with the intricacies of it? Yes, yeah, Um, 43 00:02:32,320 --> 00:02:34,200 Speaker 1: didn't you guys have one in the video department. I 44 00:02:34,200 --> 00:02:35,840 Speaker 1: don't know if everybody knows this or not, but you 45 00:02:35,880 --> 00:02:38,520 Speaker 1: originally started out you're a video guy, and then you 46 00:02:38,600 --> 00:02:41,120 Speaker 1: made the leap over to editorial and now here you are, 47 00:02:41,919 --> 00:02:45,040 Speaker 1: um and stuff you should know too. Um, but wasn't 48 00:02:45,040 --> 00:02:48,120 Speaker 1: there a three D printer in the video department for what? Ye? 49 00:02:49,000 --> 00:02:53,440 Speaker 1: And you guys made some pretty good use of that, right, Uh. Yeah. 50 00:02:53,480 --> 00:02:56,880 Speaker 1: The three D printer that we had is one of 51 00:02:56,919 --> 00:02:59,640 Speaker 1: the early models, so it has some advantages. It can 52 00:02:59,680 --> 00:03:03,639 Speaker 1: prints really cool stuff, but as pretty small, uh pretty 53 00:03:03,680 --> 00:03:07,240 Speaker 1: small production capacity, it takes a while to get to it. 54 00:03:07,240 --> 00:03:09,480 Speaker 1: It's cool. We only have one kind of plastic, so 55 00:03:09,600 --> 00:03:12,760 Speaker 1: everything is really bright green. Yes, I remember seeing that. 56 00:03:13,320 --> 00:03:17,080 Speaker 1: That's the kind of gives you a headache. Yes, yeah, 57 00:03:17,200 --> 00:03:21,359 Speaker 1: and that is that is probably um the bulk of 58 00:03:21,400 --> 00:03:23,799 Speaker 1: the cons when it gets to that. But I think 59 00:03:23,840 --> 00:03:27,959 Speaker 1: that three D printing is a fantastic and exciting thing. 60 00:03:28,520 --> 00:03:30,840 Speaker 1: And a lot of people don't know this, but not 61 00:03:30,919 --> 00:03:35,400 Speaker 1: all three D printing is created equally. There are a 62 00:03:35,400 --> 00:03:39,000 Speaker 1: couple of different types. So what we were hoping to 63 00:03:39,040 --> 00:03:42,200 Speaker 1: talk about in today's episode, right, is that h three 64 00:03:42,280 --> 00:03:45,520 Speaker 1: D printing isn't just for you know, cute little chess 65 00:03:45,560 --> 00:03:50,400 Speaker 1: pieces or car parts, right, you could do um, you 66 00:03:50,400 --> 00:03:52,360 Speaker 1: could do all sorts of things. As a matter of fact, 67 00:03:52,440 --> 00:03:56,640 Speaker 1: mentioning news stories we we recently were talking off air. 68 00:03:56,920 --> 00:03:58,800 Speaker 1: In my head, I was imagining that we were talking 69 00:03:58,880 --> 00:04:04,080 Speaker 1: off air rather about printing human tissue with a with 70 00:04:04,160 --> 00:04:07,320 Speaker 1: a three D printers. Some guys at harbor, which is 71 00:04:07,400 --> 00:04:17,880 Speaker 1: a gosh, what wake up? Wake up dude? What do 72 00:04:17,920 --> 00:04:20,480 Speaker 1: you do? Oh? Man, he got eyeboggers? Yeah, sorry about it. 73 00:04:21,160 --> 00:04:23,680 Speaker 1: That's so weird. Like I came in here, Jerry's all 74 00:04:23,680 --> 00:04:26,120 Speaker 1: set up in your asleep in your chair. I think 75 00:04:26,200 --> 00:04:30,760 Speaker 1: she put something in my coffee, you knockout pills or something. Well, 76 00:04:30,839 --> 00:04:33,159 Speaker 1: you looked like, I don't know, you were restless. Yeah, 77 00:04:33,240 --> 00:04:35,400 Speaker 1: it was weird. It has had the worst dream, like 78 00:04:36,160 --> 00:04:40,680 Speaker 1: you'd gone somewhere, some vague place no one knew where. 79 00:04:40,680 --> 00:04:45,599 Speaker 1: We weren't saying and Ben from stuff they don't want 80 00:04:45,640 --> 00:04:49,120 Speaker 1: you to know. Yeah, Ben was like in your place 81 00:04:49,320 --> 00:04:51,839 Speaker 1: and he was doing like a really good job. You 82 00:04:51,880 --> 00:04:56,680 Speaker 1: mean Ben, I left work and Ben took my job. Yeah, 83 00:04:56,839 --> 00:04:58,640 Speaker 1: I mean he was he was giving your job. He 84 00:04:58,720 --> 00:05:01,720 Speaker 1: was stepping up. Try to fill your shoes kind of thing. 85 00:05:01,920 --> 00:05:05,400 Speaker 1: He was doing good. So was it like it didn't 86 00:05:05,400 --> 00:05:07,839 Speaker 1: look like a nightmare? I gotta say, I mean it was. 87 00:05:08,240 --> 00:05:12,120 Speaker 1: It was nightmarish and that um I didn't like what 88 00:05:12,160 --> 00:05:15,839 Speaker 1: I was wearing. But Ben was doing great. So it 89 00:05:15,880 --> 00:05:17,960 Speaker 1: was a dream. It was a dream. It was a 90 00:05:17,960 --> 00:05:22,360 Speaker 1: pretty pedestrian, mundane dream. But I guess it was like 91 00:05:22,640 --> 00:05:26,080 Speaker 1: April Fool's dream of some sort. Uh you know, is 92 00:05:26,080 --> 00:05:27,880 Speaker 1: that what this is? I guess because there was a 93 00:05:27,960 --> 00:05:31,280 Speaker 1: dream today, today's April Fool's day, it all makes sense, 94 00:05:31,320 --> 00:05:34,560 Speaker 1: which would make it an April Fool's dream. Wow. Man, 95 00:05:34,839 --> 00:05:36,560 Speaker 1: All right, well you got a little drool on your 96 00:05:36,560 --> 00:05:38,480 Speaker 1: lips still, But otherwise I'm ready to go with I 97 00:05:38,760 --> 00:05:41,640 Speaker 1: have to say it was nightmarish. I'll just fess up. 98 00:05:42,120 --> 00:05:44,200 Speaker 1: The idea of doing stuff you should know without you 99 00:05:44,360 --> 00:05:47,640 Speaker 1: is you could have lead with that, you know, and 100 00:05:47,960 --> 00:05:50,480 Speaker 1: keep you in suspense. All right, Well, I'm just gonna 101 00:05:50,520 --> 00:05:54,320 Speaker 1: go have been killed very quickly, and then we probablyshod 102 00:05:54,320 --> 00:05:57,640 Speaker 1: because I mean, ask anybody who was hearing my dream 103 00:05:57,680 --> 00:06:01,000 Speaker 1: like it was. He was good. I seed his warm. Yeah, 104 00:06:01,320 --> 00:06:05,000 Speaker 1: he did do that a few times. All right. So 105 00:06:05,520 --> 00:06:08,680 Speaker 1: well here's the weird thing in my dream we were 106 00:06:08,680 --> 00:06:12,000 Speaker 1: about to talk about three D printing. What topic are 107 00:06:12,040 --> 00:06:16,960 Speaker 1: we about to cover? Now? Three D printing? What? This 108 00:06:17,040 --> 00:06:19,479 Speaker 1: is the craziest dream I've ever had in my life? 109 00:06:19,720 --> 00:06:22,400 Speaker 1: All right, my dreaming? Now, now this is for real, 110 00:06:22,480 --> 00:06:24,880 Speaker 1: like in fact, I have somewhere to be, so I'd 111 00:06:24,880 --> 00:06:27,120 Speaker 1: like to get on with it. Okay, well let's do that. 112 00:06:27,160 --> 00:06:28,880 Speaker 1: Then let's put you back to that afterward, and you 113 00:06:28,880 --> 00:06:31,080 Speaker 1: can dream about me being dead all you want, because 114 00:06:31,080 --> 00:06:35,080 Speaker 1: I still I'm kind of grog. All right, uh so chuck, Yeah, 115 00:06:35,200 --> 00:06:38,599 Speaker 1: you're ready to wrap about three D printing. Yeah, it 116 00:06:38,680 --> 00:06:41,760 Speaker 1: bugs me already that they call it printing why because 117 00:06:41,800 --> 00:06:46,360 Speaker 1: it's not printing. It's uh okay, I see where they 118 00:06:46,360 --> 00:06:48,440 Speaker 1: get the name, but it's it's to me, it's a 119 00:06:48,480 --> 00:06:51,440 Speaker 1: little bit of a confusing thing. So you're an additive 120 00:06:51,440 --> 00:06:54,960 Speaker 1: manufacturing guy, Is that what you're into? Yeah, because that's 121 00:06:55,000 --> 00:06:56,560 Speaker 1: the other term for I mean, there's a couple of 122 00:06:56,600 --> 00:06:59,760 Speaker 1: other terms summer kind of old timey, like stereo lithography. 123 00:07:00,000 --> 00:07:03,880 Speaker 1: It sounds a time um, but additive manufacturing is the 124 00:07:04,000 --> 00:07:07,160 Speaker 1: umbrella term for what three D printing is or three 125 00:07:07,240 --> 00:07:10,320 Speaker 1: D layering. I like that, Yeah, which is a little 126 00:07:10,320 --> 00:07:14,520 Speaker 1: more accurate than printing. Um. Although the reason that they 127 00:07:14,680 --> 00:07:16,800 Speaker 1: call it printing, as we will see, is because it 128 00:07:16,880 --> 00:07:21,640 Speaker 1: dovetails well with traditional two dimensional ancient printers. It uses 129 00:07:21,680 --> 00:07:23,800 Speaker 1: a lot of the same form and function. Yeah, I 130 00:07:23,800 --> 00:07:27,520 Speaker 1: get what they said. Yeah, but you mentioned additive manufacturing though. 131 00:07:27,520 --> 00:07:30,760 Speaker 1: That's the key is that it's it's not a computer 132 00:07:30,920 --> 00:07:34,240 Speaker 1: numerical controlled machining, which is when you start with a 133 00:07:34,280 --> 00:07:37,760 Speaker 1: block of something in the carpet down. This is actually 134 00:07:37,760 --> 00:07:39,800 Speaker 1: starting from nothing and adding to it, which is really neat. 135 00:07:39,800 --> 00:07:42,080 Speaker 1: It's the reverse of that. Yeah. Yeah, And with with 136 00:07:42,160 --> 00:07:44,720 Speaker 1: three D printing, I'm just gonna call it that, I'm sorry, 137 00:07:44,920 --> 00:07:49,640 Speaker 1: that's what we're gonna okay, or three D p I 138 00:07:49,800 --> 00:07:53,160 Speaker 1: call it three D p o um. And he'd say 139 00:07:53,200 --> 00:07:55,360 Speaker 1: it with like a smile and his teeth weak thing. 140 00:07:56,800 --> 00:07:59,960 Speaker 1: He's got great breath. Um he does. It's pretty pleasant. 141 00:08:00,680 --> 00:08:03,680 Speaker 1: Uh we we let's just get past the spent thing. 142 00:08:03,720 --> 00:08:07,720 Speaker 1: I'm sorry about my print okay, okay, um. So anyway, 143 00:08:07,760 --> 00:08:09,840 Speaker 1: with with three D printing, the whole basis of it 144 00:08:09,880 --> 00:08:14,200 Speaker 1: is is you you print a three dimensional object or 145 00:08:14,240 --> 00:08:18,320 Speaker 1: you manufacture a three dimensional object layer by layer by 146 00:08:18,400 --> 00:08:22,400 Speaker 1: layer by layer, layers can be a micron up to 147 00:08:22,640 --> 00:08:27,160 Speaker 1: a millimeter or so thick, and um as each layer 148 00:08:27,200 --> 00:08:29,800 Speaker 1: is deposited on top of the next, you have a 149 00:08:30,000 --> 00:08:33,000 Speaker 1: three D object that's built. That's I mean, that's there's 150 00:08:33,040 --> 00:08:37,720 Speaker 1: some total of it, like everything from I think Ben 151 00:08:37,840 --> 00:08:42,280 Speaker 1: even mentioned chess pieces to like you know whatever, I mean, 152 00:08:42,320 --> 00:08:45,600 Speaker 1: whatever you can think of. You can three D print virtually, 153 00:08:45,640 --> 00:08:50,080 Speaker 1: including guns in potentially one day, bodily organs and things 154 00:08:50,120 --> 00:08:52,360 Speaker 1: like that. Ye I can see like an artificial heart 155 00:08:52,360 --> 00:08:55,160 Speaker 1: being three D printed. They're working on it. Yeah, yep, 156 00:08:55,280 --> 00:08:57,480 Speaker 1: there's I mean, like you say, anything you can come 157 00:08:57,559 --> 00:08:59,920 Speaker 1: up with somebody who's trying to three D print or 158 00:09:00,000 --> 00:09:02,920 Speaker 1: already has. It's the latest and greatest. It is, and 159 00:09:02,960 --> 00:09:04,839 Speaker 1: in fact, Chuck, a lot of people think it's going 160 00:09:04,880 --> 00:09:08,800 Speaker 1: to be the next industrial revolution, honestly, and there's a 161 00:09:08,840 --> 00:09:11,280 Speaker 1: lot of reason to put some money behind that because 162 00:09:12,800 --> 00:09:14,920 Speaker 1: if it, if it does take off, and it's becoming 163 00:09:15,400 --> 00:09:18,319 Speaker 1: increasingly possible that it does, is costs come down for 164 00:09:18,440 --> 00:09:23,240 Speaker 1: materials and the actual printers themselves, um, the the the 165 00:09:23,280 --> 00:09:25,439 Speaker 1: more and more barriers are coming down. And if if 166 00:09:25,480 --> 00:09:31,680 Speaker 1: it becomes widespread, man, so long manufacturing and transportation sectors 167 00:09:31,720 --> 00:09:37,400 Speaker 1: as we know them. Yeah, and say hello too custom everything. Yeah, 168 00:09:37,559 --> 00:09:40,680 Speaker 1: broke your spatula in your kitchen and it's like one 169 00:09:40,720 --> 00:09:42,600 Speaker 1: in the morning and you're one of those weirdos eats 170 00:09:42,600 --> 00:09:44,320 Speaker 1: dinner at one in the morning. You get a broken 171 00:09:44,320 --> 00:09:46,920 Speaker 1: spatula and you can't go to bed, bath and beyond 172 00:09:47,000 --> 00:09:49,080 Speaker 1: or else you'd have to break in and know. All 173 00:09:49,120 --> 00:09:52,040 Speaker 1: you do is go to your your office computer at 174 00:09:52,080 --> 00:09:55,880 Speaker 1: home say hey, Amazon, I need a new spatulate. It 175 00:09:55,960 --> 00:09:58,280 Speaker 1: sends the designs to your three D printer, print, you 176 00:09:58,280 --> 00:10:01,040 Speaker 1: out a new spatula, wait till cools down, and then 177 00:10:01,080 --> 00:10:04,560 Speaker 1: you go finished cooking spaghetti. Yeah. I think the trick is, 178 00:10:04,760 --> 00:10:08,559 Speaker 1: uh is cost, Like with any kind of early technology 179 00:10:08,600 --> 00:10:12,000 Speaker 1: like this, like costs and size, that's got to come down, 180 00:10:12,040 --> 00:10:13,680 Speaker 1: and it already is. And you can buy these things 181 00:10:13,720 --> 00:10:15,640 Speaker 1: for like eight hundred bucks. Now you can get them 182 00:10:15,679 --> 00:10:18,800 Speaker 1: for I think there's you can get unassembled ones for 183 00:10:18,840 --> 00:10:21,040 Speaker 1: like two hundred. Really you can get assembled for like 184 00:10:21,080 --> 00:10:24,320 Speaker 1: three or four or five. Yeah. So alright, so should 185 00:10:24,360 --> 00:10:27,000 Speaker 1: totally have one in the office we do? Was that 186 00:10:27,240 --> 00:10:30,880 Speaker 1: was that real? What was what real? Were you controlling 187 00:10:30,880 --> 00:10:34,599 Speaker 1: my dream? I knew it? I knew you were controlling 188 00:10:34,600 --> 00:10:37,840 Speaker 1: my dream. Really, that's why I was wearing that. Yeah, 189 00:10:38,080 --> 00:10:41,439 Speaker 1: dressing up. It's a little bope. Yeah, I didn't like it. 190 00:10:42,040 --> 00:10:44,840 Speaker 1: Uh yeah, there is one somewhere and it really works 191 00:10:44,840 --> 00:10:46,800 Speaker 1: like we have used it. Yeah, I remember the did 192 00:10:46,880 --> 00:10:48,880 Speaker 1: you you have you not seen the little green like 193 00:10:48,960 --> 00:10:51,640 Speaker 1: chest pieces that he was talking about, And no, unless 194 00:10:51,640 --> 00:10:54,080 Speaker 1: I saw them and didn't realize that they're awful, some 195 00:10:54,240 --> 00:10:57,120 Speaker 1: awful neon green. But yeah, there there's a as far 196 00:10:57,200 --> 00:10:59,760 Speaker 1: as I know, it's still here. Cool. But well, you're 197 00:10:59,800 --> 00:11:01,920 Speaker 1: saying like this is kind of early on in in 198 00:11:02,480 --> 00:11:07,080 Speaker 1: the UM. It's nascent. It's a nascent technology but going fast. Yes, 199 00:11:07,840 --> 00:11:11,400 Speaker 1: and it's nascent really as far as entering people's homes 200 00:11:11,400 --> 00:11:14,679 Speaker 1: are concerned. As far as industry is concerned, it's been 201 00:11:14,720 --> 00:11:18,000 Speaker 1: around for decades now. As a matter of fact, the 202 00:11:18,040 --> 00:11:23,560 Speaker 1: mid eighties was when UM additive manufacturing, the the prototypical 203 00:11:24,080 --> 00:11:28,240 Speaker 1: three D manufacturing UM or three D printing was really 204 00:11:28,600 --> 00:11:33,320 Speaker 1: introduced to the industry sector and saying, hey, guys, you 205 00:11:33,320 --> 00:11:39,560 Speaker 1: know you're prototyping process, Well, prepare to cut it by 206 00:11:39,600 --> 00:11:44,040 Speaker 1: like seven eights. Yeah, and speed wise, speed wise, materials wise, 207 00:11:44,600 --> 00:11:48,360 Speaker 1: c O two output wise. In every way it's called 208 00:11:48,480 --> 00:11:51,400 Speaker 1: rapid prototyping, and that, like you said, in the eighties 209 00:11:51,440 --> 00:11:54,720 Speaker 1: and early nineties is when they said, you you have 210 00:11:54,800 --> 00:11:57,920 Speaker 1: some ideas for maybe a car part or something, how 211 00:11:57,920 --> 00:11:59,880 Speaker 1: would you like to And you know what prototyping is 212 00:12:00,120 --> 00:12:04,280 Speaker 1: is when you build something to test out. Basically, yes, 213 00:12:04,360 --> 00:12:07,560 Speaker 1: as a manufacturer your prototype, but um, they said, how 214 00:12:07,559 --> 00:12:12,280 Speaker 1: would you like to work with that prototype tomorrow instead 215 00:12:12,320 --> 00:12:15,079 Speaker 1: of you know, a month from now, manufactured and then 216 00:12:15,120 --> 00:12:17,800 Speaker 1: like coming up with the design sending him overseas, having 217 00:12:17,840 --> 00:12:22,520 Speaker 1: the the prototype built, shipped back to you, finding out 218 00:12:22,559 --> 00:12:26,360 Speaker 1: that it didn't quite fit, recalculating, singing it back like 219 00:12:26,480 --> 00:12:31,160 Speaker 1: this was the prototyping process until like the rapid rapid 220 00:12:31,160 --> 00:12:35,040 Speaker 1: prototyping was introduced. Yeah, and I think, like in many 221 00:12:35,080 --> 00:12:39,000 Speaker 1: cases with technology, we have m I T to Bank, 222 00:12:39,080 --> 00:12:41,920 Speaker 1: Massachusetts Institute of Technology. They were definitely one of them, 223 00:12:41,920 --> 00:12:44,880 Speaker 1: but it seems like there was a several different people 224 00:12:45,840 --> 00:12:49,200 Speaker 1: or companies or institutions that were coming up with this 225 00:12:49,280 --> 00:12:51,360 Speaker 1: at about the same time. I think car companies had 226 00:12:51,400 --> 00:12:53,880 Speaker 1: a lot of the early They definitely bought a lot 227 00:12:53,880 --> 00:12:56,559 Speaker 1: of the early ones for sure. So like in in 228 00:12:56,640 --> 00:12:59,520 Speaker 1: the in the mid eighties, a guy named Charles Hole 229 00:13:00,040 --> 00:13:02,480 Speaker 1: came up with this technique that's still in use today, 230 00:13:02,679 --> 00:13:06,480 Speaker 1: where you use a laser two turn some sort of 231 00:13:06,559 --> 00:13:11,720 Speaker 1: um plastic e dust a polymer dust into something solid. 232 00:13:12,040 --> 00:13:16,600 Speaker 1: It's called alchemy, but pretty much photo polymerization. And it 233 00:13:16,720 --> 00:13:19,319 Speaker 1: was one of the earliest types of three D printing. 234 00:13:19,440 --> 00:13:21,800 Speaker 1: And like I said, it's still in use today. Um 235 00:13:21,880 --> 00:13:24,719 Speaker 1: and Hole went on to create a company called three 236 00:13:24,800 --> 00:13:28,000 Speaker 1: D Systems that's still around today, one of the leaders 237 00:13:28,040 --> 00:13:31,840 Speaker 1: in three D printing. So he's loaded. Yeah, he's still 238 00:13:31,880 --> 00:13:35,080 Speaker 1: the CTO of the company. Uh. Well, I guess we 239 00:13:35,080 --> 00:13:38,320 Speaker 1: should talk about the two main processes on direct and 240 00:13:38,360 --> 00:13:44,240 Speaker 1: binder printing. Uh. Direct printing is uh, that's the one 241 00:13:44,280 --> 00:13:47,480 Speaker 1: that looks and behaves most like your regular like ink 242 00:13:47,559 --> 00:13:50,360 Speaker 1: jet printer when you see it moving along. It's the 243 00:13:50,400 --> 00:13:52,559 Speaker 1: little metal bars. It looks, you know, a lot like that. 244 00:13:53,360 --> 00:13:56,199 Speaker 1: It's got a little nozzle and it's gonna instead of 245 00:13:56,240 --> 00:14:00,400 Speaker 1: dispensing inc though, it dispenses either a plastic polymer or 246 00:14:00,400 --> 00:14:05,360 Speaker 1: a waxy substance, something that's heated up and melted sprayed, Yeah, 247 00:14:05,400 --> 00:14:08,280 Speaker 1: in a pattern that it's supposed to be onto the surface, 248 00:14:08,640 --> 00:14:11,360 Speaker 1: and then it cools and harden. Yeah, And that's the 249 00:14:11,440 --> 00:14:13,560 Speaker 1: key is it has to come out really hot, and 250 00:14:13,600 --> 00:14:16,559 Speaker 1: it has the cool really fast. And if you've seen 251 00:14:16,600 --> 00:14:18,600 Speaker 1: these nozzles, it's like you can think of it kind 252 00:14:18,600 --> 00:14:21,240 Speaker 1: of like a hot glue gun. Um. That's sort of 253 00:14:21,240 --> 00:14:24,960 Speaker 1: what the tip looks like, except much finer obviously, And 254 00:14:25,200 --> 00:14:29,240 Speaker 1: it'll even leave like if you're printing like uh, like 255 00:14:29,280 --> 00:14:33,720 Speaker 1: a Yoda head which people love to print, and you 256 00:14:33,840 --> 00:14:36,200 Speaker 1: have to come from the head to the ear that 257 00:14:36,280 --> 00:14:38,560 Speaker 1: sticks out, there's a gap there. There will be even 258 00:14:38,600 --> 00:14:41,360 Speaker 1: like little hot glue strings left behind the stuff you 259 00:14:41,400 --> 00:14:43,440 Speaker 1: gotta go and like clean up later, right, which is 260 00:14:43,560 --> 00:14:47,320 Speaker 1: part of the process. Um. So that's uh, that's direct 261 00:14:47,360 --> 00:14:51,400 Speaker 1: three D printing. There's another type that's similar called um 262 00:14:51,480 --> 00:14:54,880 Speaker 1: binder three D printing, and it's called binder because you 263 00:14:55,040 --> 00:15:00,360 Speaker 1: use a like your base substance is a powder, yeah, 264 00:15:00,720 --> 00:15:04,560 Speaker 1: polymer something it's but it's in powdered form and that's 265 00:15:04,560 --> 00:15:08,400 Speaker 1: sprayed or laid down in the arrangement that it's supposed 266 00:15:08,400 --> 00:15:11,240 Speaker 1: to be for that layer, and then a binder of 267 00:15:11,320 --> 00:15:14,680 Speaker 1: like glue or some sort of um liquid that holds 268 00:15:14,680 --> 00:15:18,040 Speaker 1: it in place and steals it together um is sprayed 269 00:15:18,040 --> 00:15:21,360 Speaker 1: over it. Yeah, So it's two passes, powder pass and 270 00:15:21,360 --> 00:15:23,600 Speaker 1: then the liquid paths right, and even though it's there's 271 00:15:23,640 --> 00:15:26,960 Speaker 1: two passes, it's actually faster because you don't have all 272 00:15:27,000 --> 00:15:29,640 Speaker 1: these different nozzles having to add all this different stuff. 273 00:15:29,640 --> 00:15:32,400 Speaker 1: It's just like there's your powder, there's your binder. Yeah, 274 00:15:32,440 --> 00:15:35,040 Speaker 1: and you can use that's where you can like use 275 00:15:35,080 --> 00:15:37,760 Speaker 1: metals in ceramics and things like that. It really opens 276 00:15:37,840 --> 00:15:41,720 Speaker 1: up your world material wise. And then there's multi jet modeling, 277 00:15:41,720 --> 00:15:44,600 Speaker 1: which is pretty cool. That's when you have, well you 278 00:15:44,640 --> 00:15:46,760 Speaker 1: have many of those jets and if you've seen these 279 00:15:46,800 --> 00:15:50,920 Speaker 1: things at work, it's like really cool, just all operating 280 00:15:50,920 --> 00:15:52,800 Speaker 1: at the same time, building something right in front of 281 00:15:52,800 --> 00:15:56,160 Speaker 1: your eyes, moving like little robots, spraying plastic all over 282 00:15:56,240 --> 00:16:00,280 Speaker 1: the place pretty much, um, but in very precise places. Yeah, 283 00:16:00,360 --> 00:16:03,080 Speaker 1: like you said, microns at times. And then there's another 284 00:16:03,080 --> 00:16:04,800 Speaker 1: one we wanted to give a shout out to called 285 00:16:04,840 --> 00:16:10,040 Speaker 1: fueled fuse deposition. I think yes, fuel fuse. Wow, I'm 286 00:16:10,040 --> 00:16:15,160 Speaker 1: really having trouble with this one. Fused deposition modeling, which 287 00:16:15,240 --> 00:16:19,120 Speaker 1: is basically you're using like even smaller nozzles that are 288 00:16:19,160 --> 00:16:22,800 Speaker 1: actually they're not spraying their injecting things, which gives you 289 00:16:22,840 --> 00:16:28,320 Speaker 1: an incredibly intricate amount of detail. Or amount of intricate detail, 290 00:16:28,520 --> 00:16:31,880 Speaker 1: so you get direct and binder and those are kind 291 00:16:31,960 --> 00:16:34,360 Speaker 1: of common, right, they are, yes, very common, and then 292 00:16:34,360 --> 00:16:37,880 Speaker 1: there's kind of subsets of those. There's basically, if we 293 00:16:37,960 --> 00:16:40,640 Speaker 1: did this episode five years from now, we'd be like, 294 00:16:40,680 --> 00:16:42,680 Speaker 1: here's how three D printing works. Going to be one 295 00:16:42,720 --> 00:16:45,320 Speaker 1: of these. That's what I had a feeling that as 296 00:16:45,360 --> 00:16:47,440 Speaker 1: time goes on, then some of these will fall away, 297 00:16:47,440 --> 00:16:50,280 Speaker 1: Like definitely, they're all right now, they're competing to be 298 00:16:50,440 --> 00:16:53,560 Speaker 1: basically the three D printing technology that becomes the standard 299 00:16:53,640 --> 00:16:57,760 Speaker 1: for all like inkjet. Inkjet printers were invented in the sixties, 300 00:16:58,000 --> 00:16:59,920 Speaker 1: but there was dot matrix, all these others, and then 301 00:17:00,080 --> 00:17:03,160 Speaker 1: it just became clear that inkjet printing was the way 302 00:17:03,160 --> 00:17:05,080 Speaker 1: to go. I think that's what's going on with three 303 00:17:05,119 --> 00:17:07,399 Speaker 1: D printing right now. Whichever one is most viable for 304 00:17:07,400 --> 00:17:09,240 Speaker 1: the consumer is the one that will usually went out 305 00:17:09,359 --> 00:17:11,880 Speaker 1: exactly because that's the one that companies will put all 306 00:17:11,880 --> 00:17:14,840 Speaker 1: their money into, and then that's that's where all the 307 00:17:14,880 --> 00:17:17,720 Speaker 1: breakthroughs will come from. And maybe on on the manufacturing side, 308 00:17:17,760 --> 00:17:20,320 Speaker 1: they might still have their own, like super expensive ways 309 00:17:20,320 --> 00:17:22,800 Speaker 1: of doing things, but if you want one at your house, 310 00:17:23,200 --> 00:17:24,960 Speaker 1: they're going to have to like scale it down, you 311 00:17:25,000 --> 00:17:29,080 Speaker 1: know exactly. So one of the you've got binder printing, 312 00:17:29,080 --> 00:17:31,040 Speaker 1: you've got direct three D printing, and then you have 313 00:17:31,119 --> 00:17:34,040 Speaker 1: different ways that these can be used. So um, for example, 314 00:17:34,080 --> 00:17:39,040 Speaker 1: remember I mentioned Charles Hole in his photo polymerization. Um, 315 00:17:39,080 --> 00:17:42,160 Speaker 1: that's you can use that for binding, right. So that's 316 00:17:42,240 --> 00:17:44,480 Speaker 1: the laser one. Yeah, so you would use some sort 317 00:17:44,480 --> 00:17:47,640 Speaker 1: of powder, right, and then you would use a UV 318 00:17:48,320 --> 00:17:52,639 Speaker 1: laser too that expose that powder and turned it into 319 00:17:52,640 --> 00:17:56,240 Speaker 1: a solid, right. Just I think it makes that sound. 320 00:17:56,560 --> 00:17:59,879 Speaker 1: That's why people love that three D printer. Um. So 321 00:18:00,359 --> 00:18:02,840 Speaker 1: you were using like a technically a three D bind 322 00:18:02,920 --> 00:18:06,600 Speaker 1: or printing method, but you're using photo polymerization as the 323 00:18:06,640 --> 00:18:11,000 Speaker 1: technique to actually buying this stuff together. Right. And then 324 00:18:11,040 --> 00:18:13,800 Speaker 1: depending on your material, you might want to use a 325 00:18:13,840 --> 00:18:17,879 Speaker 1: different kind of technique like um, selective laser centering is 326 00:18:17,920 --> 00:18:21,879 Speaker 1: really good for metals. Yeah, and that that's a laser 327 00:18:21,920 --> 00:18:26,760 Speaker 1: as well, and it melts actually melts this plastic powder 328 00:18:26,800 --> 00:18:29,760 Speaker 1: and then solidifies it after that, or it can melt 329 00:18:29,920 --> 00:18:33,919 Speaker 1: metal powder. So if you're creating like something that normally 330 00:18:33,920 --> 00:18:36,000 Speaker 1: would have to be like die cast or machined or 331 00:18:36,080 --> 00:18:38,840 Speaker 1: something like that, you're creating a structure that's just a 332 00:18:38,920 --> 00:18:41,800 Speaker 1: sturdy But here's the big This is one of the 333 00:18:41,800 --> 00:18:45,720 Speaker 1: reasons why three D printing could lead to a revolution 334 00:18:45,760 --> 00:18:50,959 Speaker 1: and manufacturing. Um. When you are creating something using a 335 00:18:51,000 --> 00:18:55,760 Speaker 1: three D printer, you are able to you're creating a 336 00:18:55,800 --> 00:18:59,720 Speaker 1: cross section of it layer by layer. But it's just 337 00:18:59,720 --> 00:19:04,159 Speaker 1: a dirty is something solid? Yeah, like the insides of these, 338 00:19:04,400 --> 00:19:08,480 Speaker 1: it's neither hollow nor solid. It's got like a lattice 339 00:19:09,240 --> 00:19:12,159 Speaker 1: support systems if that's what it calls for. Right, So 340 00:19:12,240 --> 00:19:14,400 Speaker 1: you can do honeycomb, you could do lattice. You can 341 00:19:14,560 --> 00:19:17,880 Speaker 1: you can subtract a lot of what has to be 342 00:19:18,200 --> 00:19:21,040 Speaker 1: in something that's die cast, just because the human hander, 343 00:19:21,080 --> 00:19:24,440 Speaker 1: the machines we have aren't capable of making something so intricate. 344 00:19:24,560 --> 00:19:27,000 Speaker 1: So you have a lot of waste in manufacturing. There's 345 00:19:27,040 --> 00:19:30,159 Speaker 1: a lot of um extra metal in a widget that 346 00:19:30,200 --> 00:19:33,280 Speaker 1: doesn't have to be there. With three D printing, you 347 00:19:33,440 --> 00:19:36,159 Speaker 1: use just the amount of material you need, and you 348 00:19:36,200 --> 00:19:40,800 Speaker 1: can make the thing as lightweight as it's structural soundness 349 00:19:41,000 --> 00:19:42,800 Speaker 1: can call for. So like if you want to make 350 00:19:42,800 --> 00:19:46,359 Speaker 1: a die cast Civil War soldier, right that's six inches tall, 351 00:19:46,760 --> 00:19:51,760 Speaker 1: it can be hollow and use less material. Right, If 352 00:19:51,800 --> 00:19:54,479 Speaker 1: you want detail in his laces, you use a three 353 00:19:54,560 --> 00:19:57,359 Speaker 1: D printer for that. If you want this clumpy Homer 354 00:19:57,400 --> 00:20:01,600 Speaker 1: Simpsons shoes, you can make it die cast. But but but 355 00:20:02,119 --> 00:20:04,520 Speaker 1: to to use an even more to the point real 356 00:20:04,560 --> 00:20:08,359 Speaker 1: world example, if you're making airplane parts and you are 357 00:20:08,440 --> 00:20:14,639 Speaker 1: making a hinge and the hinge made using die cast 358 00:20:14,720 --> 00:20:18,600 Speaker 1: techniques is blocky and clunky, and the one with three 359 00:20:18,680 --> 00:20:21,720 Speaker 1: D printing is like lattice. Like you said, the lattice 360 00:20:21,720 --> 00:20:23,639 Speaker 1: one is going to be more lightweight. If you have 361 00:20:23,760 --> 00:20:26,800 Speaker 1: a thousand hinges on a plane, all that extra weight 362 00:20:26,920 --> 00:20:29,680 Speaker 1: adds up in the die cast one. It's not there 363 00:20:29,720 --> 00:20:32,600 Speaker 1: with the three D printed one, which means the plane 364 00:20:32,920 --> 00:20:36,040 Speaker 1: weighs less, which means it uses less fuel, which means 365 00:20:36,080 --> 00:20:38,960 Speaker 1: it puts out less c O two or could carry 366 00:20:39,000 --> 00:20:41,920 Speaker 1: more even right exactly, and it's possibly even more sound 367 00:20:41,960 --> 00:20:47,000 Speaker 1: structurally because this thing has been so intricately created, why 368 00:20:47,320 --> 00:20:50,760 Speaker 1: it's really almost endless. The applications for this in the future. 369 00:20:51,200 --> 00:20:57,400 Speaker 1: Oh yeah, you spatula is to airplane hinges, Simpson civil 370 00:20:57,480 --> 00:21:00,640 Speaker 1: war figures. Well, I guess we should talk a little 371 00:21:00,640 --> 00:21:02,960 Speaker 1: bit about the process because this is where it and 372 00:21:03,000 --> 00:21:04,840 Speaker 1: you should look at a video if you haven't yet 373 00:21:04,880 --> 00:21:06,520 Speaker 1: of a three D printer in action. It's pretty neat 374 00:21:06,680 --> 00:21:10,439 Speaker 1: it is, but also it's very tough to describe UM, 375 00:21:10,480 --> 00:21:13,480 Speaker 1: and it's just so much easier to just see it. Yeah, 376 00:21:13,560 --> 00:21:17,000 Speaker 1: there's a good TED talk from I think two eleven UM. 377 00:21:17,240 --> 00:21:19,119 Speaker 1: I can't remember the woman's name, but she does a 378 00:21:19,119 --> 00:21:21,680 Speaker 1: good job of just step by step, here is the 379 00:21:21,720 --> 00:21:25,119 Speaker 1: basis of of UM three D printing. And here's some 380 00:21:25,440 --> 00:21:27,840 Speaker 1: you know, video footage that you're just like, Okay, I 381 00:21:27,880 --> 00:21:30,720 Speaker 1: totally get it now. So here's us clumsily. It's something 382 00:21:30,760 --> 00:21:36,000 Speaker 1: to explain it well. They all use a similar approach. UM. 383 00:21:36,119 --> 00:21:39,879 Speaker 1: Step one is uh C, a D computer aid to design. 384 00:21:39,920 --> 00:21:41,320 Speaker 1: This is what you have to start with. It's a 385 00:21:41,359 --> 00:21:45,520 Speaker 1: software that you know. It's the same as when you 386 00:21:45,560 --> 00:21:48,320 Speaker 1: do like a three D graphics for a motion picture. 387 00:21:48,359 --> 00:21:55,000 Speaker 1: What you're doing is just creating a three dimensional structure 388 00:21:55,080 --> 00:21:59,359 Speaker 1: on your computer screen. That's basically your blueprint. Yeah, it's 389 00:21:59,400 --> 00:22:01,520 Speaker 1: what you're gonna end making. It's CAD software. It's like 390 00:22:01,640 --> 00:22:05,000 Speaker 1: the same stuff that architects or engineers use because not 391 00:22:05,119 --> 00:22:08,239 Speaker 1: only can you design it in three dimensions, you can 392 00:22:08,280 --> 00:22:11,639 Speaker 1: also test its soundness. You can model it. Yeah, like 393 00:22:11,680 --> 00:22:14,840 Speaker 1: a big warning light goes on the breachieve model that 394 00:22:14,840 --> 00:22:18,399 Speaker 1: isn't gonna hold cars. Uh number two. And this is 395 00:22:18,440 --> 00:22:20,959 Speaker 1: some you know, kind of technical, geeky stuff, but it's 396 00:22:21,000 --> 00:22:23,840 Speaker 1: all part of the process. You have to convert that 397 00:22:23,920 --> 00:22:29,320 Speaker 1: to something called the st L format Standard Tesselation Language, 398 00:22:30,280 --> 00:22:33,520 Speaker 1: and that's basically just a file format developed in the eighties. 399 00:22:34,320 --> 00:22:40,000 Speaker 1: UM that allows the two the machine to read the 400 00:22:40,040 --> 00:22:43,560 Speaker 1: CAD software. Right, it translates it from the CAD yeah 401 00:22:43,800 --> 00:22:47,880 Speaker 1: language to the printers language. Is just a very geeky 402 00:22:47,920 --> 00:22:50,919 Speaker 1: step in the process. And that STL format that was 403 00:22:51,000 --> 00:22:53,880 Speaker 1: a Charles Whole invention to see. I wonder if if 404 00:22:53,960 --> 00:22:57,399 Speaker 1: eliminating some of these steps at some point is going 405 00:22:57,480 --> 00:22:59,680 Speaker 1: to be the deal to where you can like draw 406 00:22:59,760 --> 00:23:01,879 Speaker 1: something on your computer and plug it into your three 407 00:23:01,960 --> 00:23:06,320 Speaker 1: D printer. Yeah, I think that's kind of already there, 408 00:23:06,359 --> 00:23:08,720 Speaker 1: but you just have to have CAD and then you 409 00:23:08,800 --> 00:23:11,600 Speaker 1: can probably in CAD, I would imagine just export to 410 00:23:11,880 --> 00:23:16,520 Speaker 1: um STL format, like changing a word documentaryf or something 411 00:23:16,560 --> 00:23:18,359 Speaker 1: like that. I think it's that simple, so it's not 412 00:23:18,440 --> 00:23:21,320 Speaker 1: the big of a deal. Uh. And then you're gonna 413 00:23:21,960 --> 00:23:25,720 Speaker 1: you're gonna transfer all that to your machine, and there 414 00:23:25,800 --> 00:23:27,600 Speaker 1: is a computer that is attached to your three D 415 00:23:27,680 --> 00:23:32,600 Speaker 1: printer obviously, and so now it has the the the blueprint, 416 00:23:32,800 --> 00:23:35,960 Speaker 1: it is converted to the proper language, and it's ready 417 00:23:36,000 --> 00:23:39,199 Speaker 1: to go. Yeah, and you press the green button and 418 00:23:39,240 --> 00:23:42,199 Speaker 1: you sit back and put yourself a scotch and you 419 00:23:42,240 --> 00:23:44,840 Speaker 1: watch the magic happen. Yeah, or you go to bed 420 00:23:44,840 --> 00:23:46,879 Speaker 1: and you wake up the next day and you're like, wow, 421 00:23:46,920 --> 00:23:49,600 Speaker 1: that didn't turn out how I was supposed to. Yeah. 422 00:23:49,640 --> 00:23:51,439 Speaker 1: It does take a while, it can, at least. So 423 00:23:51,480 --> 00:23:54,800 Speaker 1: there's a there's a tumbler called Epic three D Printing Fail. 424 00:23:55,000 --> 00:23:56,640 Speaker 1: Of course there is. You should check it out. It's 425 00:23:56,720 --> 00:24:00,720 Speaker 1: um like these things go wrong, like when they go wrong, 426 00:24:00,760 --> 00:24:02,960 Speaker 1: they really go wrong. Yeah, And it's fun to go 427 00:24:03,000 --> 00:24:04,640 Speaker 1: to YouTube and see some of the people that are 428 00:24:04,640 --> 00:24:07,600 Speaker 1: doing this at home, and it's it's a process, you know, 429 00:24:07,680 --> 00:24:10,800 Speaker 1: to learn how to do it right. You know, you're 430 00:24:10,800 --> 00:24:12,719 Speaker 1: probably not going to get a great result right right 431 00:24:12,720 --> 00:24:14,840 Speaker 1: out of the gate. Yeah, and if you if you could, 432 00:24:14,840 --> 00:24:17,080 Speaker 1: it's just pure luck. Like you're gonna waste a lot 433 00:24:17,160 --> 00:24:21,040 Speaker 1: of a lot of consumables and start easy and work 434 00:24:21,080 --> 00:24:23,840 Speaker 1: your way up, as would be my advice. But you 435 00:24:23,840 --> 00:24:26,000 Speaker 1: do have to set up your machine, which means, just 436 00:24:26,040 --> 00:24:27,600 Speaker 1: like you would with your printer, you're gonna make sure 437 00:24:27,600 --> 00:24:32,280 Speaker 1: it's full of whatever polymer binder you're gonna use. Uh, 438 00:24:32,320 --> 00:24:38,680 Speaker 1: there's generally generally the the ink jets, aren't They move 439 00:24:38,880 --> 00:24:41,720 Speaker 1: left and right, and you're gonna have a base underneath 440 00:24:41,760 --> 00:24:44,200 Speaker 1: it moves it up and down. Right. They they exist, 441 00:24:44,280 --> 00:24:48,920 Speaker 1: the ink jet, the printer jets or whatever. They move 442 00:24:49,000 --> 00:24:51,480 Speaker 1: left and right, like you say, up forward and backwards, 443 00:24:51,560 --> 00:24:53,240 Speaker 1: and then yeah, the platform goes up and down to 444 00:24:53,280 --> 00:24:58,120 Speaker 1: add that third dimension. Right. So apparently with the platforms 445 00:24:58,560 --> 00:25:02,919 Speaker 1: they nickel and dime you because they're not reusable, or 446 00:25:03,040 --> 00:25:06,119 Speaker 1: if they are reusable there I think because they're heated, 447 00:25:06,440 --> 00:25:09,520 Speaker 1: they're supposed to stay heated, so I think it they Yeah, 448 00:25:10,080 --> 00:25:12,480 Speaker 1: if you look at like a package for a three 449 00:25:12,560 --> 00:25:16,359 Speaker 1: D printer you buy like replacement trade, how much are 450 00:25:16,359 --> 00:25:19,280 Speaker 1: they They're not that much, but still it's like a 451 00:25:19,520 --> 00:25:26,840 Speaker 1: it's like another expense, uh, just to print your special. Yeah, 452 00:25:27,000 --> 00:25:31,080 Speaker 1: you end up paying like hundred dollars for your stupid special. Um. So, 453 00:25:31,160 --> 00:25:33,000 Speaker 1: like I said, you're gonna let the machine do its 454 00:25:33,040 --> 00:25:35,920 Speaker 1: thing and then afterward you're gonna take it out. You 455 00:25:35,960 --> 00:25:37,719 Speaker 1: might want to check on occasionally to make sure your 456 00:25:37,800 --> 00:25:39,879 Speaker 1: goda is an all cock eye. Didn't you think that 457 00:25:40,000 --> 00:25:43,920 Speaker 1: was hilarious? Those step six removal, remove your three D 458 00:25:44,000 --> 00:25:47,240 Speaker 1: printed object from the machine, try to put the potto 459 00:25:47,280 --> 00:25:51,080 Speaker 1: spaghetti on your machine and use the spechuler like that, 460 00:25:51,160 --> 00:25:53,560 Speaker 1: actually take the special out of the machine. That does 461 00:25:53,800 --> 00:25:56,800 Speaker 1: like an unnecessary step And that's even apparently from a book. 462 00:25:57,840 --> 00:26:01,880 Speaker 1: What additive manufacturing technology is colin rapid prototyping to direct 463 00:26:01,960 --> 00:26:06,320 Speaker 1: digital manufacturing Steps six removal. Well, I think maybe they 464 00:26:06,320 --> 00:26:09,119 Speaker 1: include a removal because they do indicate that just to 465 00:26:09,160 --> 00:26:11,399 Speaker 1: be careful and you might need to wear gloves and 466 00:26:11,440 --> 00:26:14,920 Speaker 1: stuff like that. Yeah, because apparently don't forget what you're 467 00:26:14,960 --> 00:26:18,919 Speaker 1: doing is you're spraying or your machine is spraying hot 468 00:26:19,040 --> 00:26:23,720 Speaker 1: melted plastic in an enclosed location, in an enclosed room. 469 00:26:23,800 --> 00:26:27,560 Speaker 1: Probably so yeah, there's a lot of toxic chemicals involved. 470 00:26:27,760 --> 00:26:29,640 Speaker 1: You may want to wear gloves. You may want to 471 00:26:29,840 --> 00:26:35,680 Speaker 1: wear like um, a respirator, uh whatever, a Yoda mask 472 00:26:36,680 --> 00:26:40,080 Speaker 1: made with your ear. And then afterwards, like I said, 473 00:26:40,080 --> 00:26:41,359 Speaker 1: you may need to clean it up. There may be 474 00:26:41,520 --> 00:26:44,199 Speaker 1: little hairs, there may need to the things, you need 475 00:26:44,240 --> 00:26:48,200 Speaker 1: to brush off some powder and uh then dude, you're ready. Well, 476 00:26:48,240 --> 00:26:51,040 Speaker 1: some of them use supports that are water soluble too, 477 00:26:51,119 --> 00:26:55,120 Speaker 1: So like these things like that keep Yoda's ears up. Um, 478 00:26:55,600 --> 00:26:57,760 Speaker 1: they you can just drop the whole thing in water 479 00:26:57,840 --> 00:27:01,359 Speaker 1: after it cures, and then those supports go away and 480 00:27:01,720 --> 00:27:05,119 Speaker 1: because they dissolve in water, like they never happened. All right, 481 00:27:05,200 --> 00:27:07,160 Speaker 1: So we need to talk about some of the applications 482 00:27:07,200 --> 00:27:13,600 Speaker 1: now and in the future right after this message. Alright, 483 00:27:13,640 --> 00:27:17,159 Speaker 1: so the future, the future, the present, and the future 484 00:27:17,200 --> 00:27:21,680 Speaker 1: of three D printing. It's applications are really really piling up, 485 00:27:21,840 --> 00:27:26,240 Speaker 1: like daily. It seems like, yeah, Yoda figuring, that's right. 486 00:27:27,200 --> 00:27:32,360 Speaker 1: One reason is, um, the article points out, is because uh, 487 00:27:32,400 --> 00:27:34,800 Speaker 1: well there's there's a couple of fronts going on. You 488 00:27:34,840 --> 00:27:38,560 Speaker 1: have industrial manufacturing, and you have like artists. I guess 489 00:27:38,560 --> 00:27:41,400 Speaker 1: there's three, and then you have just your regular dope 490 00:27:41,440 --> 00:27:45,920 Speaker 1: at home that just has like eight bucks laying around. Uh, 491 00:27:46,000 --> 00:27:50,480 Speaker 1: and industrial manufacturing is obviously gonna speed things up like 492 00:27:50,880 --> 00:27:54,359 Speaker 1: plain wings and artificial limbs. And I saw really cool. 493 00:27:54,760 --> 00:28:00,440 Speaker 1: Did you see the three D printed cast? It was like, 494 00:28:01,000 --> 00:28:03,320 Speaker 1: you know, it wasn't solid, It was like a like 495 00:28:03,359 --> 00:28:08,240 Speaker 1: a honeycomb. So bye bye to the days of like ants, yeah, 496 00:28:08,240 --> 00:28:10,160 Speaker 1: and not be able to itch your it's your arm 497 00:28:10,240 --> 00:28:13,399 Speaker 1: or whatever. I can't sign sign those though. That's a 498 00:28:13,400 --> 00:28:18,080 Speaker 1: good point. You can't really sign the fiberglass ones anyway though. Well, 499 00:28:18,119 --> 00:28:20,119 Speaker 1: the back in the old days and it was just 500 00:28:20,160 --> 00:28:22,879 Speaker 1: plaster like those were the that was the heyday of 501 00:28:22,960 --> 00:28:27,359 Speaker 1: cats signing. And then when they went to not fiberglass, 502 00:28:27,359 --> 00:28:29,040 Speaker 1: what is it they used the I don't even know. 503 00:28:29,080 --> 00:28:32,640 Speaker 1: I haven't broken a limb. Now. It's not titanium. It's 504 00:28:32,680 --> 00:28:37,679 Speaker 1: more like the fabric bandage that ends up hardenings. You 505 00:28:37,720 --> 00:28:39,840 Speaker 1: can't write on it. I can't do anything with it. 506 00:28:40,120 --> 00:28:42,200 Speaker 1: No one asked me to sign their cast anyway, so 507 00:28:42,520 --> 00:28:44,160 Speaker 1: I don't. I don't keep up with the cast. Does 508 00:28:44,200 --> 00:28:46,320 Speaker 1: anyone even do that anymore? Or is that a totally 509 00:28:46,360 --> 00:28:51,400 Speaker 1: antiquated thing. I'm sure they do. Um No, I didn't 510 00:28:51,400 --> 00:28:53,720 Speaker 1: see the cast to answer your question. Okay, but that's 511 00:28:53,800 --> 00:28:57,959 Speaker 1: that's industrial manufacturing. They're tackling like the big things like 512 00:28:58,120 --> 00:29:00,760 Speaker 1: organs and car parts and playing parts. And that's actually 513 00:29:00,800 --> 00:29:05,520 Speaker 1: the second sea change that additive manufacturing has created for 514 00:29:05,720 --> 00:29:09,800 Speaker 1: the industrial sector. Because first of all, they revolutionized prototyping, 515 00:29:10,240 --> 00:29:12,680 Speaker 1: and then these three D printers got so good that 516 00:29:12,720 --> 00:29:15,120 Speaker 1: they're like, well, we can actually produce the actual thing, 517 00:29:15,680 --> 00:29:18,360 Speaker 1: like not just the prototype of the model anymore. We 518 00:29:18,400 --> 00:29:23,440 Speaker 1: can produce the actual end result. So that's the second revolution, 519 00:29:23,480 --> 00:29:26,080 Speaker 1: and it's it's very much here now, Like, hey, you're 520 00:29:26,120 --> 00:29:30,720 Speaker 1: a surgeon and Josh was in a horrible accident and 521 00:29:30,800 --> 00:29:32,560 Speaker 1: his face was disfigured and you want to put them 522 00:29:32,560 --> 00:29:36,240 Speaker 1: back together. We can print out your old lovely face 523 00:29:36,760 --> 00:29:41,280 Speaker 1: and show that surgeon shove it under the skin. Yeah, 524 00:29:41,840 --> 00:29:43,680 Speaker 1: we can't do that obviously, but it just serves as 525 00:29:43,720 --> 00:29:45,880 Speaker 1: the model for the surgeon out instead of looking at 526 00:29:45,880 --> 00:29:48,440 Speaker 1: it on a computer screen. Right. Um, and there's a 527 00:29:48,720 --> 00:29:51,840 Speaker 1: there's apparently m R I S or f m R 528 00:29:51,880 --> 00:29:55,960 Speaker 1: I s are going to be pretty much delivering the 529 00:29:56,000 --> 00:29:59,520 Speaker 1: CAD file to a three D printer pretty soon to 530 00:29:59,640 --> 00:30:02,720 Speaker 1: create oh yeah, yeah, to create stuff that you need. 531 00:30:03,280 --> 00:30:04,800 Speaker 1: All you do is just get an m R I 532 00:30:04,840 --> 00:30:08,200 Speaker 1: skin and then bam, here's your implant. Apparently it's all 533 00:30:08,200 --> 00:30:11,760 Speaker 1: the rage and dental implants. Yeah, you know, I got 534 00:30:11,840 --> 00:30:15,560 Speaker 1: my fake tooth, which took a long time to manufacture 535 00:30:15,640 --> 00:30:17,840 Speaker 1: because they weren't using three D printers now, but they 536 00:30:17,840 --> 00:30:22,680 Speaker 1: could whip out a tooth for me tomorrow. Ten seconds. Um. 537 00:30:22,880 --> 00:30:25,720 Speaker 1: Artists are way into it. UM. If you've been to 538 00:30:25,840 --> 00:30:28,160 Speaker 1: a an art show in the past couple of years, 539 00:30:28,160 --> 00:30:31,880 Speaker 1: you've probably seen some sort of three D printed um 540 00:30:31,960 --> 00:30:36,360 Speaker 1: object UM. Which I feel like at this point, a 541 00:30:36,400 --> 00:30:39,120 Speaker 1: lot of the art that's being three D printed, it's 542 00:30:39,160 --> 00:30:42,880 Speaker 1: more like it's made by three D printers. It's the 543 00:30:42,920 --> 00:30:45,880 Speaker 1: big thing. Yeah, yeah, it's not. Wow, it's really amazing 544 00:30:46,200 --> 00:30:48,080 Speaker 1: and it was made by three D It's more like 545 00:30:48,160 --> 00:30:50,200 Speaker 1: this is made by a three D printer. Yeah, But 546 00:30:50,280 --> 00:30:54,120 Speaker 1: for me, I'd still I guess it's impressive, but I'd 547 00:30:54,120 --> 00:30:57,000 Speaker 1: still rather see a sculpture by hand that's something that 548 00:30:57,080 --> 00:30:59,800 Speaker 1: was three D printed, you know, I mean that seems 549 00:30:59,800 --> 00:31:04,680 Speaker 1: to be a lot more difficult the old school. Um. 550 00:31:04,840 --> 00:31:07,800 Speaker 1: There's also like a lot of that's kind of doves 551 00:31:07,960 --> 00:31:11,200 Speaker 1: dovetails and with art is um. You know, you can 552 00:31:11,240 --> 00:31:14,960 Speaker 1: buy a piece of art now that's someone sculpted using 553 00:31:15,000 --> 00:31:18,200 Speaker 1: CAD and print it out at your house and then 554 00:31:18,440 --> 00:31:21,600 Speaker 1: you have a piece by that artist. It's kind of 555 00:31:21,680 --> 00:31:26,800 Speaker 1: changing art as well. UM. There's also a that's also 556 00:31:26,880 --> 00:31:31,600 Speaker 1: kind of being revolutionized in commerce as well. So like um, 557 00:31:31,640 --> 00:31:33,640 Speaker 1: I guess going back to the medical thing, there's a 558 00:31:33,680 --> 00:31:36,880 Speaker 1: company called the spoke prosthetics where they can kind of 559 00:31:36,920 --> 00:31:39,120 Speaker 1: measure your stuff and create a model for it and 560 00:31:39,160 --> 00:31:43,080 Speaker 1: then print out your prosthetic that's super tailored. Or you know, 561 00:31:43,160 --> 00:31:46,560 Speaker 1: going back to that spatial example, you know, you can 562 00:31:46,680 --> 00:31:50,040 Speaker 1: ultimately have some design sent to your three D printer 563 00:31:50,480 --> 00:31:52,800 Speaker 1: and then you print out your special So you're paying 564 00:31:52,800 --> 00:31:55,440 Speaker 1: for the design and that only has to be designed 565 00:31:55,440 --> 00:31:58,680 Speaker 1: once and then it's on it's on the person who 566 00:31:58,760 --> 00:32:01,560 Speaker 1: is buying it. It's up to you to manufacture it. 567 00:32:02,040 --> 00:32:03,840 Speaker 1: So that kind of takes a lot of the costs 568 00:32:03,840 --> 00:32:06,440 Speaker 1: away too. It's really just you don't even have to 569 00:32:06,480 --> 00:32:08,720 Speaker 1: build that first one. You just come up with a 570 00:32:08,760 --> 00:32:10,840 Speaker 1: good design and you can sell the design over and 571 00:32:10,880 --> 00:32:14,520 Speaker 1: over again without ever actually manufacturing anything. Right, Or if 572 00:32:14,560 --> 00:32:18,800 Speaker 1: you just think of some cool little thing you want built, um, 573 00:32:18,840 --> 00:32:21,240 Speaker 1: maybe your own prototype of something you can you don't 574 00:32:21,280 --> 00:32:23,120 Speaker 1: even have to buy all the stuff. There are companies 575 00:32:23,160 --> 00:32:26,160 Speaker 1: now that will make your little prototype for you. Yeah, 576 00:32:26,360 --> 00:32:28,560 Speaker 1: which is I think far more prevalent these days. Like 577 00:32:28,600 --> 00:32:31,720 Speaker 1: if you do order something off the internet, they'll, um, 578 00:32:32,080 --> 00:32:34,840 Speaker 1: they'll they send the file to a company that actually 579 00:32:34,880 --> 00:32:37,160 Speaker 1: prints it out for you. And there's a professional job. 580 00:32:37,920 --> 00:32:41,800 Speaker 1: Unless you want it yourself, for like the home inventoring, 581 00:32:41,800 --> 00:32:43,560 Speaker 1: you know, and they want to try out their new 582 00:32:43,560 --> 00:32:46,920 Speaker 1: widget that they just made. Speaking of home inventors, we 583 00:32:46,960 --> 00:32:49,440 Speaker 1: would be very remiss. Its not in this article. But 584 00:32:49,760 --> 00:32:52,960 Speaker 1: there is another, yet another revolution. If you haven't gotten 585 00:32:52,960 --> 00:32:56,520 Speaker 1: the idea that three D printing is revolutionary, just rewind 586 00:32:56,560 --> 00:33:01,600 Speaker 1: this and start over. UM. The there's a three D 587 00:33:01,640 --> 00:33:06,280 Speaker 1: printer called a rep wrap, which is a but it's 588 00:33:06,320 --> 00:33:09,800 Speaker 1: a d I Y from scratch three D printer that 589 00:33:09,840 --> 00:33:12,000 Speaker 1: you build. You build, you can get the parts that 590 00:33:12,200 --> 00:33:15,800 Speaker 1: just just about anywhere UM for a couple of hundred bucks, 591 00:33:16,320 --> 00:33:19,000 Speaker 1: and you put it together and you download the open 592 00:33:19,000 --> 00:33:22,640 Speaker 1: source software. All this is free, all open source UM. 593 00:33:22,680 --> 00:33:25,080 Speaker 1: And the first thing the printer does is it prints 594 00:33:25,080 --> 00:33:27,880 Speaker 1: out the remaining parts that it needs. Shut up, swear 595 00:33:27,880 --> 00:33:32,360 Speaker 1: to god. It's in its second incarnation now, second generation 596 00:33:32,400 --> 00:33:35,960 Speaker 1: rep wrap is called the mendel Ter gregor mendel UM. 597 00:33:36,040 --> 00:33:38,640 Speaker 1: And once you have this thing up and running, there's 598 00:33:38,680 --> 00:33:42,280 Speaker 1: like a whole world of open source UM three D 599 00:33:42,360 --> 00:33:46,160 Speaker 1: printing projects that you can download and print. You can 600 00:33:46,240 --> 00:33:48,640 Speaker 1: upload your own stuff. And the great part about it, 601 00:33:48,720 --> 00:33:51,200 Speaker 1: since it's open source, if somebody's like this would be 602 00:33:51,240 --> 00:33:54,240 Speaker 1: so much better if we just replaced this lattice structure 603 00:33:54,640 --> 00:33:57,520 Speaker 1: with a honeycomb structure here, and then all of a sudden, 604 00:33:57,520 --> 00:34:00,400 Speaker 1: now it's indestructible and then bam, that thing just got 605 00:34:00,400 --> 00:34:04,840 Speaker 1: improved for everybody to come. Yeah, this sounds like something 606 00:34:04,880 --> 00:34:07,840 Speaker 1: that's like early Internet stuff that at some point some 607 00:34:08,360 --> 00:34:12,080 Speaker 1: government being will squatch. Well yeah, well, I mean all 608 00:34:12,120 --> 00:34:15,520 Speaker 1: this free trading of great ideas and things. Exactly. One 609 00:34:15,520 --> 00:34:17,920 Speaker 1: of the things is the people who are open source 610 00:34:18,400 --> 00:34:22,120 Speaker 1: fanatics are like, dude, you want to solve poverty. You 611 00:34:22,120 --> 00:34:25,080 Speaker 1: want to solve like, um, poor healthcare in these areas 612 00:34:25,160 --> 00:34:28,759 Speaker 1: like give the give a town a three D printer two, 613 00:34:29,280 --> 00:34:31,040 Speaker 1: or teach them how to how to set up a 614 00:34:31,080 --> 00:34:34,520 Speaker 1: mental and then they can print out their lab parts, 615 00:34:34,600 --> 00:34:37,360 Speaker 1: they can print out replacement parts, they can print out whatever, 616 00:34:38,080 --> 00:34:41,400 Speaker 1: and all of a sudden they can take care of 617 00:34:41,440 --> 00:34:45,359 Speaker 1: themselves and give deliver good health care. And there's not 618 00:34:45,440 --> 00:34:48,920 Speaker 1: they're not relying on you know, aid or donors or whatever. 619 00:34:49,440 --> 00:34:53,160 Speaker 1: They're they're handling it themselves because now they're not off 620 00:34:53,160 --> 00:34:56,680 Speaker 1: of the supply line. They're totally tapped in just because 621 00:34:56,719 --> 00:34:59,040 Speaker 1: they have an Internet connection and a three D printer. Well, 622 00:34:59,040 --> 00:35:01,640 Speaker 1: and you sent me an article about a gentleman who 623 00:35:01,680 --> 00:35:06,440 Speaker 1: is working on three D printing food, and um, I 624 00:35:06,760 --> 00:35:08,879 Speaker 1: don't think of it as like I'm gonna go print 625 00:35:08,880 --> 00:35:11,040 Speaker 1: a hamburger. You have to kind of change your conception 626 00:35:11,040 --> 00:35:14,840 Speaker 1: of what food is. But it's essentially gonna be a 627 00:35:14,960 --> 00:35:19,200 Speaker 1: mix of you know, water and proteins and oils and 628 00:35:19,320 --> 00:35:23,239 Speaker 1: whatever makes up the components of a food. And then 629 00:35:23,239 --> 00:35:26,280 Speaker 1: he printed out as a little cube or a little 630 00:35:26,480 --> 00:35:29,680 Speaker 1: four leaf clover and eat it. Yeah. I don't know 631 00:35:29,680 --> 00:35:32,279 Speaker 1: about I mean, it's way early in the stages, but 632 00:35:32,320 --> 00:35:35,000 Speaker 1: he's talking about solving world hunger with three D printing. Yeah, 633 00:35:35,040 --> 00:35:37,520 Speaker 1: and he totally could because if you have the macro 634 00:35:37,680 --> 00:35:42,120 Speaker 1: nutrients right, like you have a protein cartridge, a carbohydrate cartridge, 635 00:35:42,160 --> 00:35:45,839 Speaker 1: and fast cartridge, and you're using binder printing, so you're 636 00:35:45,880 --> 00:35:49,399 Speaker 1: just putting them together and adding water or something like that. Um, 637 00:35:49,480 --> 00:35:53,000 Speaker 1: instant food, right. So his his first proof of concept 638 00:35:53,000 --> 00:35:54,680 Speaker 1: I think was chocolate, but the one he's working on 639 00:35:54,800 --> 00:35:57,520 Speaker 1: now is pizza, which is perfect because it's in the 640 00:35:57,600 --> 00:36:02,480 Speaker 1: layers anyway. So, UM, remember the the the platform that 641 00:36:02,560 --> 00:36:04,839 Speaker 1: goes up and down as he did often. The guy 642 00:36:04,880 --> 00:36:09,360 Speaker 1: who created that, he he used, Um that characteristic to 643 00:36:09,840 --> 00:36:13,960 Speaker 1: bake the dough as it's the pizzas being built like 644 00:36:14,120 --> 00:36:17,080 Speaker 1: at the carb layer and then the tomato layer, and 645 00:36:17,080 --> 00:36:20,600 Speaker 1: then a protein layer, and the proteins come from like 646 00:36:20,719 --> 00:36:23,759 Speaker 1: insects or whatever, which if you're eating it, if it 647 00:36:23,840 --> 00:36:26,680 Speaker 1: tastes right, you don't care where it comes from, of course, 648 00:36:27,239 --> 00:36:29,960 Speaker 1: unless you pay attention to that kind of thing. But yeah, 649 00:36:30,040 --> 00:36:33,520 Speaker 1: he could very easily like that could totally revolutionized food. 650 00:36:33,800 --> 00:36:36,640 Speaker 1: And as we get closer to things like being able 651 00:36:36,680 --> 00:36:41,399 Speaker 1: to three D print living tissue, which apparently we're at 652 00:36:41,560 --> 00:36:44,680 Speaker 1: right there, but the the problem that everybody keeps running 653 00:36:44,719 --> 00:36:48,239 Speaker 1: up against his blood vessels, generating blood vessels just just 654 00:36:48,360 --> 00:36:51,239 Speaker 1: beyond our technology right now. Once we start being able 655 00:36:51,239 --> 00:36:53,160 Speaker 1: to do that, then you will be able to print 656 00:36:53,239 --> 00:36:57,400 Speaker 1: a nice, juicy hamburger in your home, Manu. Some of 657 00:36:57,440 --> 00:37:00,239 Speaker 1: the some of the downsides of three D printing is 658 00:37:00,880 --> 00:37:03,000 Speaker 1: as of now, and and I think a lot of 659 00:37:03,000 --> 00:37:04,960 Speaker 1: this stuff, like with anything and technology is going to 660 00:37:05,040 --> 00:37:07,319 Speaker 1: get better. They're gonna refine it and make it more 661 00:37:07,760 --> 00:37:11,799 Speaker 1: environmentally friendly. But right now, uh, they burn a lot 662 00:37:11,840 --> 00:37:15,160 Speaker 1: of energy, about fifty to a hundred times more electrical 663 00:37:15,280 --> 00:37:19,560 Speaker 1: energy than injection molding for something that's you know, similar 664 00:37:19,600 --> 00:37:23,839 Speaker 1: in size, so that's no good. A hundred times more 665 00:37:23,840 --> 00:37:27,759 Speaker 1: electricity is traditional casting or machining. So right now they're 666 00:37:27,840 --> 00:37:30,200 Speaker 1: recommending it. It's it's not up to like large scale 667 00:37:30,239 --> 00:37:34,160 Speaker 1: manufacturing or anything like that, right like assembly line stuff, 668 00:37:35,239 --> 00:37:37,919 Speaker 1: just because it's just burning too much, is wasting too much. 669 00:37:38,800 --> 00:37:42,759 Speaker 1: The emissions aren't very healthy. Um. Obviously, if you have 670 00:37:42,800 --> 00:37:44,080 Speaker 1: one of these in your home, like you said, you're 671 00:37:44,080 --> 00:37:48,359 Speaker 1: an enclosed space, you're burning plastic um, there's gonna be 672 00:37:48,440 --> 00:37:51,840 Speaker 1: some emissions giving off given off from that in your house. 673 00:37:52,560 --> 00:37:54,640 Speaker 1: So if you know, I don't know what kind of 674 00:37:54,680 --> 00:37:58,200 Speaker 1: they probably have venting systems already, don't they. I don't know. 675 00:37:58,280 --> 00:38:01,200 Speaker 1: If you in an industrial and I'm sure like they say, 676 00:38:01,280 --> 00:38:03,600 Speaker 1: you should probably put this in a vented room. But no, 677 00:38:03,760 --> 00:38:07,239 Speaker 1: if you're just a dude with a maker bought on 678 00:38:07,320 --> 00:38:10,520 Speaker 1: your desktop, it's in your it's in your room. Yeah, 679 00:38:10,719 --> 00:38:14,719 Speaker 1: your rooms as vented as it normally, as I would guess. Uh, 680 00:38:14,840 --> 00:38:18,920 Speaker 1: plastics is something we're trying to get away from UM 681 00:38:18,960 --> 00:38:22,440 Speaker 1: as a planet, and plastic filament is kind of the 682 00:38:22,520 --> 00:38:26,200 Speaker 1: main game right now. Yeah, for for now, I mean, 683 00:38:26,239 --> 00:38:29,640 Speaker 1: like as as metals and ceramics, are more and more introduced. 684 00:38:29,640 --> 00:38:32,160 Speaker 1: I think, you know, plastics will kind of fall away 685 00:38:32,239 --> 00:38:35,120 Speaker 1: or they could, but yeah, for sure, like all three 686 00:38:35,200 --> 00:38:38,600 Speaker 1: D printers use plastics right now. You know this one 687 00:38:38,640 --> 00:38:40,400 Speaker 1: I would never consider. I thought it was pretty interesting, 688 00:38:40,480 --> 00:38:44,120 Speaker 1: is that the piracy uh licensing deals of Like if 689 00:38:44,160 --> 00:38:48,000 Speaker 1: you want to go make your own hobbit figuring instead 690 00:38:48,000 --> 00:38:53,000 Speaker 1: of paying what's the dude's name, Pete Peter Jacks, Peter 691 00:38:53,080 --> 00:38:56,440 Speaker 1: Jackson his cut, or George Lucas his cut, you can 692 00:38:56,440 --> 00:38:59,800 Speaker 1: make your own Little Star Wars figures or or printed 693 00:38:59,800 --> 00:39:01,480 Speaker 1: but to him and go sell him in the subway. 694 00:39:02,200 --> 00:39:07,200 Speaker 1: Kids who don't know any different who ride the subway. Yeah, 695 00:39:07,239 --> 00:39:08,960 Speaker 1: we're set up on your own, you know, your own 696 00:39:09,719 --> 00:39:11,719 Speaker 1: online shopper or whatever. You know. Yeah, And I mean, 697 00:39:11,800 --> 00:39:14,600 Speaker 1: like you can make the argument like, yeah, that's I mean, 698 00:39:14,640 --> 00:39:17,200 Speaker 1: that's a problem, and but that's something that would have 699 00:39:17,239 --> 00:39:21,520 Speaker 1: to be dealt with, just like everyone lived with the 700 00:39:21,560 --> 00:39:24,399 Speaker 1: piracy from music and movies and all that. Like those 701 00:39:24,440 --> 00:39:27,360 Speaker 1: industries haven't collapsed. It's true. People are still making music, 702 00:39:27,400 --> 00:39:30,879 Speaker 1: people are still making movies, people will still make figurines. Yeah, 703 00:39:30,920 --> 00:39:33,080 Speaker 1: that's a good point. And then the whole gun thing 704 00:39:33,200 --> 00:39:36,960 Speaker 1: is definitely a touchy issue. Yeah. This guy, Cody Wilson, 705 00:39:37,280 --> 00:39:40,600 Speaker 1: twenty six years old, a couple of years ago, Yeah, 706 00:39:40,760 --> 00:39:43,279 Speaker 1: was it last year? Was like within the last two 707 00:39:43,360 --> 00:39:45,800 Speaker 1: years I think, made it his own three D printed 708 00:39:45,800 --> 00:39:50,040 Speaker 1: gun that shot a bullet, and um, they have now 709 00:39:50,120 --> 00:39:54,880 Speaker 1: even another company has manufactured a metal gun that shoots bullets. 710 00:39:55,880 --> 00:39:59,600 Speaker 1: And that means if you can sell that software, then 711 00:40:00,000 --> 00:40:02,480 Speaker 1: book could just skirt gun laws and print a gun 712 00:40:02,560 --> 00:40:06,560 Speaker 1: at home. Yes, apparently they already are. Um. I guess 713 00:40:06,880 --> 00:40:09,480 Speaker 1: Cody Wilson put it up in the Justice Department took 714 00:40:09,520 --> 00:40:12,440 Speaker 1: it down, but not before it was already downloaded a 715 00:40:12,520 --> 00:40:16,719 Speaker 1: hundred thousand times at least. And that's the that's a 716 00:40:16,760 --> 00:40:19,960 Speaker 1: magic number. That means it's out there forever. Yeah, and 717 00:40:19,960 --> 00:40:24,680 Speaker 1: apparently the Congress has already got laws regarding this. Um 718 00:40:24,719 --> 00:40:27,440 Speaker 1: as far as having guns that are not made of 719 00:40:27,480 --> 00:40:29,640 Speaker 1: metal or like i e. One that you could sneak 720 00:40:29,640 --> 00:40:32,400 Speaker 1: onto a plane. But there's a small loophole in that 721 00:40:32,560 --> 00:40:35,600 Speaker 1: some of these gun plans have like the tiniest little 722 00:40:35,640 --> 00:40:39,360 Speaker 1: piece of metal that maybe not picked up by a 723 00:40:39,400 --> 00:40:43,360 Speaker 1: metal detector, but it is untill technically metal, right, and 724 00:40:43,520 --> 00:40:48,680 Speaker 1: it's deliberator does have that. It does have that piece 725 00:40:49,320 --> 00:40:52,040 Speaker 1: a metal piece. But apparently if if you have the plans, 726 00:40:52,040 --> 00:40:53,959 Speaker 1: you can very easily go in and ex that part 727 00:40:53,960 --> 00:40:56,600 Speaker 1: out and you have an all plastic gun. Right. Apparently 728 00:40:56,640 --> 00:41:00,960 Speaker 1: this Arai Israeli television group printed out their own version 729 00:41:01,000 --> 00:41:03,879 Speaker 1: of it, and um I wanted to see how far 730 00:41:03,920 --> 00:41:06,480 Speaker 1: they could get with one, and basically we're standing right 731 00:41:06,520 --> 00:41:11,759 Speaker 1: next to Benjamin and Yahoo with this plastic gun on them. 732 00:41:11,800 --> 00:41:14,280 Speaker 1: They were able to smuggle it all the way into 733 00:41:14,520 --> 00:41:19,439 Speaker 1: Parliament um on on the news. So I mean, yeah, 734 00:41:19,480 --> 00:41:22,879 Speaker 1: it's it's it's a plastic gun that you could take 735 00:41:22,960 --> 00:41:25,400 Speaker 1: through a metal detector, which is a great thing to 736 00:41:25,560 --> 00:41:27,959 Speaker 1: unleash on the world. And this guy's a what about 737 00:41:27,960 --> 00:41:30,520 Speaker 1: the bullets? I don't know, Yeah, I don't. I don't 738 00:41:30,600 --> 00:41:32,600 Speaker 1: understand why it wouldn't be picked up or whatever. But 739 00:41:32,840 --> 00:41:36,719 Speaker 1: or maybe they could make plastic bullets. Yeah, but you're 740 00:41:36,719 --> 00:41:40,759 Speaker 1: just shooting somebody with plastic bullets. It's like, yeah, jerk, Yeah, 741 00:41:40,760 --> 00:41:43,120 Speaker 1: they already make those and they sell them it TWI us. Yeah. 742 00:41:43,440 --> 00:41:46,279 Speaker 1: I read this Guardian article and it was like, you know, 743 00:41:46,480 --> 00:41:50,280 Speaker 1: this kid is a he's very much like um russ Olbrick. 744 00:41:50,440 --> 00:41:57,080 Speaker 1: He was like a libertarian slash anarchists kinda, and um, 745 00:41:57,840 --> 00:42:00,799 Speaker 1: he was like, well, it's not my responsibile that I 746 00:42:00,920 --> 00:42:04,480 Speaker 1: just you know, I unleashed this on the world. Who cares, right, 747 00:42:04,840 --> 00:42:06,920 Speaker 1: you can't. You can't govern this kind of thing. The 748 00:42:06,920 --> 00:42:09,920 Speaker 1: Internet is supposed to be free, and it's like, and 749 00:42:10,040 --> 00:42:12,080 Speaker 1: that is a that is a can of worms that 750 00:42:12,160 --> 00:42:14,680 Speaker 1: I don't think exists in black and white. Yeah, Or 751 00:42:14,719 --> 00:42:17,600 Speaker 1: who's responsible legally for some of this stuff one day, 752 00:42:17,680 --> 00:42:20,799 Speaker 1: like the manufacturer of the software or you know, but 753 00:42:20,880 --> 00:42:26,000 Speaker 1: even beyond legally, who's responsible morally? Yeah? You know you 754 00:42:26,160 --> 00:42:29,000 Speaker 1: are my friend, not me, not you, but the individual. 755 00:42:30,239 --> 00:42:32,839 Speaker 1: You're not gonna print a gun, No, you'll just print 756 00:42:32,880 --> 00:42:37,920 Speaker 1: out a little figures have been Man, that's dream. You 757 00:42:38,000 --> 00:42:40,279 Speaker 1: got anything else? Right now? I got nothing else. I 758 00:42:40,320 --> 00:42:43,280 Speaker 1: think it's a good overview. Yeah it is. We'll revisit 759 00:42:43,280 --> 00:42:45,200 Speaker 1: in five years and talk about which one one out. 760 00:42:46,040 --> 00:42:49,319 Speaker 1: This article is hilariously out of date. The lowest, the 761 00:42:49,360 --> 00:42:56,000 Speaker 1: lowest price it quotes is it something? It doesn't even 762 00:42:56,000 --> 00:42:59,960 Speaker 1: mention the rep rap, the rep rap, it's the big deal. Okay. 763 00:43:00,480 --> 00:43:03,399 Speaker 1: Uh So if you want to learn more about three 764 00:43:03,520 --> 00:43:05,960 Speaker 1: D printing, you should go read this hilariously out of 765 00:43:06,040 --> 00:43:08,160 Speaker 1: date article. On house top works, which by the way, 766 00:43:08,360 --> 00:43:11,000 Speaker 1: is being updated to put in an update requests, so 767 00:43:11,160 --> 00:43:15,439 Speaker 1: it should be nice and fancy soon. Um. And since 768 00:43:15,480 --> 00:43:17,479 Speaker 1: I said search bar, I think I did, It's time 769 00:43:17,520 --> 00:43:23,720 Speaker 1: for listener mail. I'm gonna call this wild parrots. Remember 770 00:43:23,760 --> 00:43:28,960 Speaker 1: when we talked about the wild parrots confirmed, Um, hey, 771 00:43:29,000 --> 00:43:31,600 Speaker 1: guys really enjoyed hanging out with you during the Tattoo podcast. 772 00:43:31,680 --> 00:43:35,440 Speaker 1: By the way, it is called a tattoo machine, not 773 00:43:35,520 --> 00:43:38,279 Speaker 1: a tattoo gun. Apparently they don't like that. They don't 774 00:43:38,320 --> 00:43:41,759 Speaker 1: like that, and we heard about it tattoo people. Are 775 00:43:42,360 --> 00:43:48,879 Speaker 1: they tattoo people? Um? Burning man people and who who else? 776 00:43:48,960 --> 00:43:50,920 Speaker 1: Seems like there's been one more subset of people that 777 00:43:50,920 --> 00:43:55,520 Speaker 1: you wouldn't think just be so like angry. Yeah. I 778 00:43:55,600 --> 00:43:59,640 Speaker 1: can't think of anybody any other group that's responded on 779 00:43:59,760 --> 00:44:04,600 Speaker 1: mat so angrily. Yeah, burning man and tattoos. Uh. So, 780 00:44:04,640 --> 00:44:07,720 Speaker 1: when Josh heard um that parrots like to hang together 781 00:44:08,400 --> 00:44:10,480 Speaker 1: when free, I wanted to burst into the podcast room 782 00:44:10,480 --> 00:44:12,920 Speaker 1: and tell you about the wild parrots of San Francisco, 783 00:44:13,040 --> 00:44:15,800 Speaker 1: my hometown. I'm not gonna get into it except to 784 00:44:15,840 --> 00:44:17,960 Speaker 1: say that over the course of my life, the parents 785 00:44:17,960 --> 00:44:19,880 Speaker 1: were sort of a living legend that one would occasionally 786 00:44:19,880 --> 00:44:22,399 Speaker 1: get the privilege of spotting now and then. However, about 787 00:44:22,400 --> 00:44:25,000 Speaker 1: three years ago I moved in with my aunt in 788 00:44:25,040 --> 00:44:29,200 Speaker 1: the little San Francisco suburb of Brisbane, and apparently the 789 00:44:29,239 --> 00:44:31,680 Speaker 1: famous flock of parrots were also making their home there, 790 00:44:32,120 --> 00:44:34,719 Speaker 1: since it was warmer and less windy than most of 791 00:44:34,719 --> 00:44:37,520 Speaker 1: San Francisco. Uh. They were often hanging out right outside 792 00:44:37,560 --> 00:44:40,320 Speaker 1: my bedroom window, which is pretty amusing but also someone annoying, 793 00:44:40,680 --> 00:44:43,479 Speaker 1: especially since my first son was just a little guy 794 00:44:43,560 --> 00:44:46,239 Speaker 1: and they are loud. I can vouch for that they're 795 00:44:46,280 --> 00:44:49,080 Speaker 1: super loud. Also, guys, I'm sending you the link to 796 00:44:49,200 --> 00:44:52,719 Speaker 1: watch the documentary from two thousand three, The Wild Parrots 797 00:44:53,120 --> 00:44:58,400 Speaker 1: of Telegraph Hill. So she's recommended that we watched that. Anyway, 798 00:44:58,560 --> 00:45:02,600 Speaker 1: did we get that documentary? No? I think it's Um. Yeah, 799 00:45:02,640 --> 00:45:06,920 Speaker 1: it was just a link. It's online, so keep it up. Seriously, 800 00:45:07,000 --> 00:45:10,400 Speaker 1: if you stopped making podcasts, I'd be one that majorly bummed. 801 00:45:10,560 --> 00:45:18,240 Speaker 1: Mama Child Bellow Amy, Thanks Amy and San Francisco via Italy. 802 00:45:19,480 --> 00:45:24,400 Speaker 1: Yeah that was weird. Um that it was good. I 803 00:45:24,440 --> 00:45:26,360 Speaker 1: didn't doubt you. I want to say, Oh no, I 804 00:45:26,360 --> 00:45:28,879 Speaker 1: didn't think so, okay, I that would just be such 805 00:45:29,040 --> 00:45:33,200 Speaker 1: a bizarre thing to make up. Um, but yeah, thanks 806 00:45:33,280 --> 00:45:38,040 Speaker 1: Amy for supporting Chuck. Chuck loves to be supported and proven, right, 807 00:45:39,280 --> 00:45:41,399 Speaker 1: don't we. All.
