WEBVTT - 3D Printer of the Gods II 0:00:04.120 --> 0:00:07.000 Welcome to Stuff to Blow Your Mind from how Stuff 0:00:07.000 --> 0:00:13.800 Works dot com. Hey, welcome to Stuff to Blow your Mind. 0:00:13.800 --> 0:00:16.400 My name is Robert Lamb And and this is part 0:00:16.440 --> 0:00:20.040 two of our two parter on three D printing three 0:00:20.160 --> 0:00:23.119 D printers of the Gods. Uh. The idea here and 0:00:23.200 --> 0:00:26.119 the snazzy title, of course, refers to the idea that 0:00:26.440 --> 0:00:30.440 three D printers essentially allow almost any idea that's out 0:00:30.440 --> 0:00:32.800 there to take physical form, which in a way is 0:00:32.880 --> 0:00:35.920 kind of kind of godlike and it and it forces 0:00:36.000 --> 0:00:38.280 us to really rethink what the future is going to be, like, 0:00:38.320 --> 0:00:40.440 what our relationship with objects is going to be, and 0:00:40.440 --> 0:00:42.479 really also it makes us sort of think about what 0:00:42.479 --> 0:00:44.760 our relationship with objects is now. We talked in the 0:00:44.800 --> 0:00:47.440 last podcast about some of the current things that are 0:00:47.479 --> 0:00:50.800 going on, such as Devantie is wearing a dress that 0:00:50.840 --> 0:00:54.360 it was three D printed, people trying to three D 0:00:54.480 --> 0:00:57.600 print the perfect plastic gun like an actual gun that 0:00:57.680 --> 0:01:02.720 kills people, oxygen aryans printing out novelty adult toys exactly, 0:01:03.560 --> 0:01:07.880 novelty to us exactly. And uh, and today we're going 0:01:07.959 --> 0:01:09.760 to we we talked a little bit about the future 0:01:09.760 --> 0:01:11.920 in the last one, but this time we're gon we're 0:01:11.959 --> 0:01:14.520 gonna go a little more detailed on that. We're going 0:01:14.560 --> 0:01:18.440 to talk about some of the near future revolutions in 0:01:18.520 --> 0:01:21.479 three D printing that are really going to change the world. 0:01:21.760 --> 0:01:25.440 It's true because although three D printers aren't quite the 0:01:25.480 --> 0:01:28.800 transporter devices we hoped for at this point, the fact 0:01:28.840 --> 0:01:31.480 of the matter is that they are rearranging matter and 0:01:31.520 --> 0:01:33.920 they are sort of defined space and time when it 0:01:33.959 --> 0:01:38.319 comes to objects, into consumerism and to making what you 0:01:38.360 --> 0:01:41.080 want when you want it. So some of the things 0:01:41.080 --> 0:01:43.880 that are going to be happening very soon with three 0:01:43.959 --> 0:01:46.960 D printing um that are going to change everything. First 0:01:46.959 --> 0:01:50.080 of all, we're looking at three D printing reaching the 0:01:50.120 --> 0:01:53.400 industrial strength level. Now, three D printing, as we've mentioned before, 0:01:53.480 --> 0:01:56.360 has been a part of industry for about twenty years now, 0:01:56.520 --> 0:02:00.240 and it's been useful in UH create rapidly producing UH 0:02:00.520 --> 0:02:04.360 prototypes in some cases. But we're talking about a situation 0:02:04.440 --> 0:02:07.160 where three D printing will be able to produce objects 0:02:07.200 --> 0:02:11.799 of high quality, industrial grade that can be that can 0:02:11.840 --> 0:02:15.200 be a part of automobiles, etcetera. And now some automobiles 0:02:15.240 --> 0:02:17.560 already have through some three D printing parts, but we're 0:02:17.560 --> 0:02:20.359 talking about an age win pretty much all parts are 0:02:20.360 --> 0:02:22.160 going to be produced by three D printing as opposed 0:02:22.200 --> 0:02:26.720 to traditional subtractive methods such as printing the pieces out 0:02:26.720 --> 0:02:29.400 of a sheet of metal or using a mold to 0:02:29.560 --> 0:02:32.360 pour and pouring a mold to create the device. Yeah, 0:02:32.360 --> 0:02:34.000 because I mean, at the end of the day, when 0:02:34.000 --> 0:02:36.639 you're when you're talking about the future three D printing, 0:02:36.639 --> 0:02:40.040 you're talking about materials that are lighter, that can be 0:02:40.320 --> 0:02:43.720 made faster, and can be customized. So it's a perfect 0:02:43.720 --> 0:02:46.720 fit for manufacturing. Um, So you know you're going to 0:02:46.800 --> 0:02:50.560 see more of these printers and factories just printing out parts. 0:02:51.120 --> 0:02:55.399 You also see them in the nano manufacturing industry, which 0:02:55.400 --> 0:02:57.480 will talk more about. And then you look at you're 0:02:57.480 --> 0:03:00.400 gonna see it just in actual like hey, we're gonna 0:03:00.400 --> 0:03:03.800 build something. We're gonna build a building, and so imagine 0:03:03.880 --> 0:03:07.760 large blocks of like custom building materials being printed out 0:03:07.840 --> 0:03:10.480 on a job site. Yeah. And and to go back 0:03:10.480 --> 0:03:13.280 to prototyping real quick, you're just gonna see that that 0:03:13.400 --> 0:03:16.720 speeded up even more. The ability to quickly produce a 0:03:16.760 --> 0:03:19.840 working prototype for for a new product. It's just gonna 0:03:19.880 --> 0:03:22.640 be it's gonna be exponentially improved. Yeah. In fact, the 0:03:22.720 --> 0:03:26.239 D shape printer, which was created by Enricodini, is capable 0:03:26.320 --> 0:03:30.160 now of printing a two story building complete with rooms, stairs, pipes, 0:03:30.200 --> 0:03:34.120 and partitions, and it uses nothing but sand an inorganic 0:03:34.240 --> 0:03:37.760 binding compound, and then the resulting material has the same 0:03:37.840 --> 0:03:41.280 durability as reinforced concrete. With this is super cool the 0:03:41.320 --> 0:03:45.240 look of marble um. Of course, now you can only 0:03:45.600 --> 0:03:49.400 use this on rounded structures, but the process itself takes 0:03:49.440 --> 0:03:52.600 approximately about a fourth of the time as traditional buildings, 0:03:53.560 --> 0:03:57.720 and it doesn't really require any specialized knowledge or skill set. Yeah, 0:03:57.720 --> 0:03:59.240 because a lot of the you know, we get into 0:03:59.280 --> 0:04:01.920 the idea of printing nano materials, and we've talked before 0:04:01.960 --> 0:04:05.440 about like when whether we're talking about space elevators or 0:04:05.600 --> 0:04:08.320 super tall buildings, we always come back around to the 0:04:08.400 --> 0:04:10.400 use of nano materials because when you're building things from 0:04:10.400 --> 0:04:13.040 the smallest level up, which to a certain extent is 0:04:13.080 --> 0:04:15.000 three D printing in itself. It's the idea that I'm 0:04:15.000 --> 0:04:17.520 starting small and building everything up from the bottom. But 0:04:17.560 --> 0:04:20.000 if you start really small, if you're building things up 0:04:20.000 --> 0:04:23.880 from the from the smallest structures possible, then you're able 0:04:23.920 --> 0:04:29.080 to create super strong materials capable of tethering a space 0:04:29.120 --> 0:04:33.720 elevator in place, or creating the sort of skyscrapers that 0:04:33.880 --> 0:04:36.520 right now we can only dream of. It doesn't change physics, 0:04:36.600 --> 0:04:40.160 but it changes the way that materials act in in 0:04:40.200 --> 0:04:43.440 the realm of physics, which is really cool because that 0:04:43.560 --> 0:04:46.800 is really liberating as as someone who is a designer 0:04:46.880 --> 0:04:49.120 in someone who is trying to do something like see 0:04:49.160 --> 0:04:51.800 a spacecraft. Yeah, I mean, it's the difference between me 0:04:51.960 --> 0:04:55.239 selling two things together, or me sewing up a hole 0:04:55.320 --> 0:04:58.560 in my hoodie or something as opposed to to an 0:04:58.600 --> 0:05:02.400 actual scene stress or an or or sewing machine doing it. Um. 0:05:02.440 --> 0:05:05.359 And you know, in the difference between a big visible 0:05:05.680 --> 0:05:08.200 um stitch and an invisible stitch. And it's just the 0:05:08.520 --> 0:05:12.200 finer level of detail, the finer grade of craftsmanship that 0:05:12.279 --> 0:05:14.120 you get when you when you build things up from 0:05:14.120 --> 0:05:17.560 that very small level. And when you're speaking about building 0:05:17.600 --> 0:05:19.200 up things for a very small level, of course, you 0:05:19.400 --> 0:05:23.120 start thinking about the medical ramifications that this because we're 0:05:23.120 --> 0:05:26.520 built up very small exactly exactly, um. And we have 0:05:26.640 --> 0:05:30.119 experiments and printing soft tissue that are underway now. UM. 0:05:30.160 --> 0:05:33.200 But the idea is that if if you can master that, 0:05:33.360 --> 0:05:36.680 you may begin to print veins and arteries to you 0:05:36.920 --> 0:05:40.360 to be used in operations and then um, you know, 0:05:40.400 --> 0:05:44.280 taking to the extreme, you can then print organs and 0:05:44.839 --> 0:05:47.240 you're not even taking into the strain. The extreme is 0:05:47.279 --> 0:05:50.000 of course printing the whole bodies. Yeah, I mean, which 0:05:50.120 --> 0:05:53.839 not only would would vanquish the whole organ uh donor 0:05:54.080 --> 0:05:56.760 problem that we have, right, but I mean you write 0:05:56.760 --> 0:05:59.240 you just hey, here's another me. Yeah, I'm just going 0:05:59.279 --> 0:06:01.840 to keep it in the and storage until I need 0:06:01.839 --> 0:06:04.000 to replace myself. And this is a great example of 0:06:04.240 --> 0:06:06.520 three D printer of the gods here, because we're essentially 0:06:06.600 --> 0:06:11.200 talking about a three D printer creating objects, creating a 0:06:11.279 --> 0:06:14.160 person as nature creates a person. You know, the the 0:06:14.200 --> 0:06:16.840 idea that it's it's just it's created from the smallest piece, 0:06:16.839 --> 0:06:19.680 it's it's grown. Yeah, there is an element of bio 0:06:19.760 --> 0:06:21.880 mimicry about this. We'll talk about this more when we 0:06:21.920 --> 0:06:25.360 talk about four D printing. But um, it is interesting 0:06:25.360 --> 0:06:27.520 that we're getting sort of back to the basics when 0:06:27.560 --> 0:06:29.800 we're talking about three D printing, because it really is 0:06:29.839 --> 0:06:33.760 sort of saying, let's take take nature's way of building 0:06:33.880 --> 0:06:37.159 up and see if we can recreate this process in 0:06:37.160 --> 0:06:41.960 a machine. Um. Consumerism, Yes, this is gonna be huge. 0:06:42.839 --> 0:06:44.760 I mean, this is what I think is going to 0:06:44.839 --> 0:06:47.919 be one of the most interesting aspects about three D 0:06:47.960 --> 0:06:50.200 printing because I think it will greatly change our behavior. 0:06:50.240 --> 0:06:52.279 And you and I talked about this in the last 0:06:52.279 --> 0:06:55.599 podcast last episode. Is that you know, one day you 0:06:55.640 --> 0:06:58.000 could go to Amazon and you could click on a 0:06:58.040 --> 0:06:59.960 box there that says I want to customize this because 0:07:00.000 --> 0:07:03.560 as Amazon has now decided to use this technology with 0:07:03.920 --> 0:07:08.359 their companies, um in their manufacturers, and it's just gonna 0:07:08.360 --> 0:07:11.240 be something pretty wrote like, Hey, I need to get 0:07:11.240 --> 0:07:13.240 this new SYNC, but I really would love to have 0:07:14.120 --> 0:07:17.640 I don't know, some sort of crazy design of vampire 0:07:17.720 --> 0:07:21.120 state building, yeah, you know in it or I don't know. Yeah, 0:07:21.120 --> 0:07:23.640 I mean, and we already have some of those options, 0:07:23.640 --> 0:07:25.520 for instance, with some of our our digital and some 0:07:25.640 --> 0:07:28.320 non digital media media. You want a book, okay, if 0:07:28.320 --> 0:07:29.840 you want it in hardback? You want and soft back? 0:07:29.840 --> 0:07:33.480 You want in paperback? Or do you want it uh? Digital? Right? Uh? 0:07:33.480 --> 0:07:34.960 And how do you want that album? Do you want 0:07:35.000 --> 0:07:37.560 it joined vinyl, you want it on c D, you 0:07:37.600 --> 0:07:39.840 want it on a retrocassette which is coming back in 0:07:39.840 --> 0:07:42.360 some case? Do you or you want it digitally? All right? Well, 0:07:42.360 --> 0:07:44.280 we have five options for that. You want to in flak, 0:07:44.320 --> 0:07:46.320 you want an MP three, you want it, and and 0:07:46.400 --> 0:07:48.000 you know, it just goes on and on. So you'll 0:07:48.040 --> 0:07:50.040 see that kind of stuff when you buy things. All right, 0:07:50.080 --> 0:07:51.600 what size do you want it? In? What color do 0:07:51.640 --> 0:07:54.840 you want it? Also upload the dimensions of your hand 0:07:55.200 --> 0:07:58.480 to upload that your actual physical dimensions, and we'll make 0:07:58.480 --> 0:08:00.240 sure that it fits you to a t us. So 0:08:00.240 --> 0:08:02.240 try to imagine that. So let's say that you want 0:08:02.280 --> 0:08:04.240 a specific design that you can get to pick from 0:08:04.280 --> 0:08:07.920 all these stock files of this specific design or you 0:08:07.960 --> 0:08:10.960 know stock art, and then yeah, you can upload if 0:08:10.720 --> 0:08:13.000 it if the object relates to your body, then you 0:08:13.120 --> 0:08:18.120 upload your own dimensions and then Amazon surely will deliver 0:08:18.200 --> 0:08:20.520 that to you within the hour because now even now 0:08:20.560 --> 0:08:23.400 they're trying to do same day delivery. So we have wait. 0:08:23.440 --> 0:08:25.280 Since we're extrapolating in the future, we have to think 0:08:25.280 --> 0:08:27.560 about this, you know, five years out. Yeah, and you're 0:08:27.600 --> 0:08:29.480 gonna see that It's going to be like with any 0:08:29.480 --> 0:08:32.800 technological innovation, there are going to be companies that adapt 0:08:32.880 --> 0:08:34.959 and shift and survive, and then they're gonna be ones 0:08:35.000 --> 0:08:36.800 that fall to the wayside, and there are going to 0:08:36.880 --> 0:08:40.080 be new entrepreneurs that that pop up that are like, hey, 0:08:40.160 --> 0:08:42.360 this is how people are going to be consuming. What 0:08:42.400 --> 0:08:43.760 can we do to game it? They're going to be 0:08:43.760 --> 0:08:47.320 products that come out that are specifically aimed at three 0:08:47.400 --> 0:08:49.200 D printing. Well, see, I'm glad that you brought that up, 0:08:49.200 --> 0:08:51.480 because it really does change the landscape of companies in 0:08:51.679 --> 0:08:54.760 their ability to produce. So, you know, I wonder does 0:08:54.840 --> 0:08:59.319 Amazon then begin to produce items instead of just distribute, 0:09:00.160 --> 0:09:03.480 because essentially they can take over if you can print anything, 0:09:03.559 --> 0:09:07.200 then why even half manufacturers that you distribute? Why why 0:09:07.280 --> 0:09:11.079 just um, why not just be the point persona and 0:09:11.120 --> 0:09:12.920 then that process? And then to what extent did these 0:09:12.920 --> 0:09:15.800 companies become the means of creating? You know? I mean 0:09:16.000 --> 0:09:18.800 because like we mentioned before, I mean everybody, everybody wants 0:09:18.840 --> 0:09:21.200 to to be an artist, Everyone wants to be a writer, 0:09:21.280 --> 0:09:23.839 everyone wants to be a musician to varying degrees that 0:09:23.920 --> 0:09:26.920 the Internet is a great example of all sorts of 0:09:26.920 --> 0:09:29.720 different people producing something and wanting to share it with 0:09:29.760 --> 0:09:32.319 the world. And then take that and translated to the 0:09:32.360 --> 0:09:35.280 world of objects. So do these companies end up becoming 0:09:35.320 --> 0:09:38.080 more and more involved in user generated content like the 0:09:38.120 --> 0:09:43.840 Wikipedia of objects? Right? And you know our our storefronts 0:09:43.880 --> 0:09:46.440 replaced by just a storefront. Yeah. Do you go to 0:09:46.440 --> 0:09:50.520 the mall and it's just one uh three D printing kiosk. 0:09:50.679 --> 0:09:53.439 We'll probably multiple chaos where you go in and you 0:09:53.440 --> 0:09:55.200 you print out the things you want. I mean maybe 0:09:55.200 --> 0:09:57.000 you have a situation where the stores are still there 0:09:57.480 --> 0:09:59.520 so that you can you can shop. People like to 0:09:59.600 --> 0:10:02.079 look at things before they buy them. But then when 0:10:02.080 --> 0:10:04.480 you decide you print it out. You go to the kiosks, 0:10:04.480 --> 0:10:06.400 you print it out, and you can print out you know, 0:10:06.440 --> 0:10:09.320 your your new shoes, your new dress, the toy for 0:10:09.360 --> 0:10:12.560 the kid, uh and maybe even your hamburger. I would 0:10:12.559 --> 0:10:13.880 but just say you could also pray. If you're a 0:10:13.920 --> 0:10:16.000 little bit you know, you feel like you mean a gnash, 0:10:16.120 --> 0:10:19.400 then hey you can. This is an ability that Cornelling 0:10:19.480 --> 0:10:23.160 University's fab Home fab at Home project can actually do 0:10:23.320 --> 0:10:26.160 right now. They use gel like substances that can be 0:10:26.240 --> 0:10:30.920 combined with other materials, including artificial flavor yeum uh to 0:10:31.000 --> 0:10:34.200 mimic the taste in mouth feel of many different foods. Yeah, 0:10:34.200 --> 0:10:36.240 this was really interesting because they also talked a little 0:10:36.240 --> 0:10:38.880 bit about the the Uncanny Valley of foods with this 0:10:38.960 --> 0:10:43.240 because because the gel like substance called hydro collides is 0:10:44.480 --> 0:10:48.120 is apparently a little unsettling, like it's filled with artificial flavoring. 0:10:48.480 --> 0:10:50.480 And you can print it, say, in the shape of 0:10:50.480 --> 0:10:52.920 a turkey leg, sure, but if it doesn't taste like 0:10:52.960 --> 0:10:55.360 a turkey leg, it's gonna be a little weird. So 0:10:55.679 --> 0:10:57.520 they they've really kind of decided that they need to 0:10:57.559 --> 0:10:59.640 work on the taste first and then worry about printing 0:10:59.640 --> 0:11:01.800 it out in to the four into the actual shapes, 0:11:02.520 --> 0:11:05.280 which which makes sense, and maybe to a certain extent 0:11:05.320 --> 0:11:07.440 it's I mean, it makes me think of candy, right, 0:11:07.640 --> 0:11:11.640 and specifically banana flavored candy. You ever had banana flavored candy? 0:11:12.240 --> 0:11:14.839 It doesn't taste like bananas, and to a certain extent, 0:11:14.880 --> 0:11:17.720 orange candy doesn't taste like oranges. But you get into 0:11:17.800 --> 0:11:20.960 that area, how close can the taste be to the 0:11:21.040 --> 0:11:23.240 thing and still get away with it? And to what 0:11:23.320 --> 0:11:27.520 extent it does it become a new thing because orange 0:11:27.760 --> 0:11:30.719 candy it's nothing like an actual orange in flavor or 0:11:30.760 --> 0:11:33.160 in texture. But I know, I was just thinking about 0:11:33.200 --> 0:11:34.960 to the twenties, and we talked about um when we 0:11:35.000 --> 0:11:36.680 did the food episode, and we were talking about the 0:11:36.720 --> 0:11:39.880 candy that became a stand in for a meal, because remember, 0:11:40.480 --> 0:11:44.959 people didn't have much money and they had those turkey 0:11:45.000 --> 0:11:47.720 meals and it was I don't know if it actually 0:11:47.960 --> 0:11:51.439 was supposed to taste like a roast turkey or I 0:11:51.480 --> 0:11:54.240 think I think they had chocolate and it was the idea. 0:11:54.280 --> 0:11:57.880 The idea was, hey, you need a meal, here's a meal. 0:11:58.160 --> 0:12:00.800 Peel it back and eat it. So we have evidence 0:12:00.800 --> 0:12:03.520 that we've done this before, and certainly if you don't 0:12:03.520 --> 0:12:06.120 have the resources, then maybe you can't accept that. And 0:12:06.240 --> 0:12:08.480 after all, it's a shot of glucose. Anyways, look at 0:12:08.559 --> 0:12:11.000 some of the stuff people eat already, Like a chicken 0:12:11.080 --> 0:12:14.840 nugget is nothing like anything real. It's you know, it's 0:12:15.160 --> 0:12:17.679 it's you know, you look at stuff with pink slime. 0:12:17.720 --> 0:12:21.200 I mean, we're already magnufacturing unreal food out of strange things. 0:12:21.240 --> 0:12:24.360 So and people and people love it. So um, pink 0:12:24.360 --> 0:12:26.880 slime is found in hamburger meat, right, yeah, yeah, So 0:12:26.920 --> 0:12:30.080 I I have no doubt that three D printing could 0:12:30.120 --> 0:12:34.040 easily create something that people would love, if not tolerate. Specifically, 0:12:34.040 --> 0:12:36.360 when you're talking about like say, long term space missions, 0:12:36.880 --> 0:12:39.160 I mean these are environments where, yes, you want people 0:12:39.240 --> 0:12:41.760 in space to want to eat because sometimes there's less 0:12:41.760 --> 0:12:45.800 of an appetite there. But but ultimately you know, survival 0:12:45.800 --> 0:12:48.679 food right well, And so that just made me think 0:12:48.679 --> 0:12:53.160 about the parallels between the Uncanny Valley and smell racams 0:12:53.240 --> 0:12:56.000 for food, right because there are some people who will 0:12:56.040 --> 0:12:58.840 say the Uncanny Valley isn't as uncanny or creepier as 0:12:58.920 --> 0:13:01.360 we think. You know, see a robot that's supposed to 0:13:01.480 --> 0:13:03.240 look like a human or act like a human, or 0:13:03.240 --> 0:13:05.480 move like a human and they don't because they are 0:13:05.559 --> 0:13:09.080 not in it unsettles us. But we get used to things. 0:13:09.320 --> 0:13:11.600 I mean, new food is uncanny Valley when you first 0:13:11.640 --> 0:13:14.160 have it, like you know, have Thai food for the 0:13:14.200 --> 0:13:16.559 first time, and you'll be like, this is a little uncanny, 0:13:16.600 --> 0:13:18.680 but you know you'll love it in a week. So 0:13:19.160 --> 0:13:22.360 guarantee you guaranteed. All Right, we're gonna take a quick 0:13:22.400 --> 0:13:24.840 break and when we come back, we're gonna talk even 0:13:24.840 --> 0:13:26.480 more about the future of three D printing and we're 0:13:26.480 --> 0:13:32.160 going to talk about four D printing. All Right, we're 0:13:32.200 --> 0:13:34.920 back and we're gonna talk here about four D printing. 0:13:34.960 --> 0:13:37.720 And just to be clear, the term four D printing 0:13:37.840 --> 0:13:40.920 is a it's a little bit of science headline bait. 0:13:41.240 --> 0:13:44.400 It's misleading. Yeah, it's it's it looks great in the headline, 0:13:44.440 --> 0:13:46.600 but when you really get down to the meat of it, 0:13:46.600 --> 0:13:49.120 it's not. You're not really printing in space and time, 0:13:49.440 --> 0:13:51.480 no more than you're always printing in space and time. 0:13:51.920 --> 0:13:54.600 It's kind of like three D printing on steroids. Um. 0:13:54.679 --> 0:13:56.360 And what we're talking about, we're talking about for D 0:13:56.440 --> 0:13:59.839 printing is passive self assembly systems, which is still pretty 0:13:59.840 --> 0:14:02.240 odd them. Don't let me underplay it. It's very cool. 0:14:03.120 --> 0:14:06.240 Self assembly m I T. Researcher Skylar Tipbitts is sort 0:14:06.240 --> 0:14:08.040 of the face of this right now in terms of 0:14:08.040 --> 0:14:12.199 self assembly. And when I talk about it being on steroids, 0:14:12.200 --> 0:14:16.040 we're talking about its allowing three D printers allowing to 0:14:16.840 --> 0:14:20.640 print parts to self assemble and reassemble into a number 0:14:20.720 --> 0:14:23.760 of products. So each part would be comprised of a 0:14:23.840 --> 0:14:27.520 regular rigid plastic layer along with an outer layer made 0:14:27.560 --> 0:14:30.960 up smart materials, not dumb ones. And then when they're 0:14:30.960 --> 0:14:34.640 submerged in water, the smart materials absorb and they expand 0:14:34.720 --> 0:14:36.640 and they cause the parts to move and form a 0:14:36.720 --> 0:14:40.520 pre specified object. It's like if you're wearing kite jeans 0:14:41.120 --> 0:14:43.080 and then you, and then you get reined on really 0:14:43.120 --> 0:14:45.120 heavy layer. You fall in a swimming pool, and then 0:14:45.160 --> 0:14:47.160 they start to shrink up, and then you were your 0:14:47.240 --> 0:14:50.520 your form changes and you you you go into into 0:14:50.600 --> 0:14:53.160 like stiff legged mode because you can't move your legs anymore. 0:14:53.760 --> 0:14:55.640 It's kind of like that the outer layer is the 0:14:55.720 --> 0:14:59.360 gene the blue jeans, and then the inner layer is you. Yeah, well, 0:14:59.400 --> 0:15:01.560 I mean think it's really interesting. And this is uh 0:15:01.640 --> 0:15:03.880 from a Ted talk that you sent me that Tibbott 0:15:03.960 --> 0:15:06.640 is talking about the future of this and what makes 0:15:06.640 --> 0:15:09.200 no sense so much sense. He's saying that currently we 0:15:09.320 --> 0:15:14.240 build skyscrapers with about five hundred thousand into one million parts, 0:15:14.520 --> 0:15:17.040 which all told takes about two years. And that's not 0:15:17.240 --> 0:15:21.440 even counting the dead gangsters in the concrete exactly or 0:15:21.480 --> 0:15:24.560 the vampires, um. And then he says though that we 0:15:24.600 --> 0:15:28.360 should look toward natural systems to get a better idea 0:15:28.400 --> 0:15:31.640 of how to use forty or self assembly. He says 0:15:31.640 --> 0:15:34.520 that we have proteins that have two million types, they 0:15:34.520 --> 0:15:37.960 can fold in ten thousand nanoseconds, and he says we 0:15:37.960 --> 0:15:40.680 also have DNA with three billion base pairs we can 0:15:40.720 --> 0:15:44.840 replicate in roughly an hour. So he said that out 0:15:44.880 --> 0:15:49.520 of all this complexity complexity in our natural systems, UM, 0:15:49.560 --> 0:15:52.680 there's still this idea that they're really efficient at what 0:15:52.760 --> 0:15:55.480 they do, far more efficient than anything that we can build, 0:15:56.000 --> 0:15:58.520 and far more complex than anything that we can build. 0:15:59.000 --> 0:16:01.240 And so he says we should look towards this model 0:16:01.440 --> 0:16:05.400 because it's it's really good, um and making something out 0:16:05.440 --> 0:16:08.600 of as little energy as possible. Yeah, I mean, and 0:16:08.720 --> 0:16:11.880 right now we're talking about again a little like a 0:16:11.920 --> 0:16:14.280 three D printed stick that when the water is at 0:16:14.320 --> 0:16:17.040 it, it it becomes a cube. But he's talking long term 0:16:17.280 --> 0:16:20.600 the idea of the self assembly of large scale structures, 0:16:21.040 --> 0:16:23.080 which is which is pretty phenomenal. I like how in 0:16:23.120 --> 0:16:24.880 the talk he gets a little philosophic too and talks 0:16:24.920 --> 0:16:29.120 about ultimately objects that have desire. Not only do we 0:16:29.280 --> 0:16:32.320 desire them, but they have they have a desire in 0:16:32.360 --> 0:16:34.680 the sense that there is something that they will be. 0:16:34.800 --> 0:16:37.680 I mean, it gets a little we want Yeah, when 0:16:37.720 --> 0:16:38.920 you get into one. I mean, it's kind of like 0:16:38.920 --> 0:16:41.560 when you're talking about memory, like say a spring having 0:16:41.600 --> 0:16:43.400 memory of spring. It doesn't have memory in the sense 0:16:43.400 --> 0:16:47.600 that we speak of it, but it does have engineering, uh, 0:16:47.640 --> 0:16:50.480 in a physics level of memory. And this would be 0:16:50.640 --> 0:16:53.560 that same level of desire. So you could also argue 0:16:53.600 --> 0:16:56.120 to say, my earbuds always have a desire to break 0:16:56.160 --> 0:16:58.880 after one year. Well, this is uh. This kind of 0:16:58.880 --> 0:17:01.880 goes back to Susan Black when she talks about Dawkins. 0:17:01.880 --> 0:17:06.080 She talks about memes and how humans are just meme machines, right, 0:17:06.119 --> 0:17:10.080 We're meant to communicate certain messages and over and over 0:17:10.119 --> 0:17:12.320 again and just spread the memes. But then she says 0:17:12.359 --> 0:17:15.399 technology is really the thing that we're spreading. So that's 0:17:15.400 --> 0:17:18.880 why she plays on teams UM And so I think 0:17:18.880 --> 0:17:22.639 about this in that instance, like we are creating UM 0:17:22.720 --> 0:17:27.520 the technology to ultimately reproduce itself and brings us back 0:17:27.520 --> 0:17:29.520 into the world of nanotech. But I was gonna say, really, 0:17:29.520 --> 0:17:33.399 at a very small scale, which is now um possible 0:17:33.440 --> 0:17:37.159 in nano three D printing, I cause you're talking about 0:17:37.320 --> 0:17:42.880 really fine resolutions that enable the creation of intricately structured sculptures. 0:17:43.000 --> 0:17:47.080 Is tiny, tiny, tiny, tiny as a grain of sand. 0:17:47.520 --> 0:17:49.840 There's actually a great video we'll we'll try to remember 0:17:49.880 --> 0:17:52.600 to post this, but it shows that in fifty seconds 0:17:53.280 --> 0:17:56.720 this aircraft is created through a nano three D printer, 0:17:57.280 --> 0:17:59.840 and if you look at it through obviously there's like 0:18:00.080 --> 0:18:04.719 magnified and you see the details and it is perfectly scale. 0:18:04.840 --> 0:18:07.600 It's it's a beautiful rendering and it is an object 0:18:07.680 --> 0:18:10.720 and it is as big as a tiny grain of salt. Yeah. 0:18:10.760 --> 0:18:13.159 I mean it comes back into again to what I've 0:18:13.160 --> 0:18:15.040 been talking about with the idea of building things with 0:18:15.119 --> 0:18:18.200 the smallest parts possible. The more that the smaller that 0:18:18.320 --> 0:18:21.120 the building blocks, the more power you have over the structure, 0:18:21.640 --> 0:18:24.720 over the ultimate finished product. It's like with legos. Think 0:18:24.760 --> 0:18:27.040 back to the legos you had when you were really young, 0:18:27.440 --> 0:18:30.320 whether it were kind of big and and boxy because 0:18:30.400 --> 0:18:32.040 it would be harder to fit in your mouth, and 0:18:32.080 --> 0:18:35.080 then the smaller legos you eventually grew into, which one 0:18:35.160 --> 0:18:37.640 would which blocks allow you to create the more detailed 0:18:37.640 --> 0:18:40.600 model the smaller blocks of course, of course. And then 0:18:40.600 --> 0:18:42.879 when you think about something that we mentioned before, the 0:18:42.880 --> 0:18:46.080 gaming controllers, in which there's the ability to throw down 0:18:46.119 --> 0:18:49.680 to lay down electronics and those objects that are three 0:18:49.760 --> 0:18:52.240 D printed, and you look at nano printing and you 0:18:52.280 --> 0:18:54.320 know it's just a matter of time where you can 0:18:54.359 --> 0:18:57.960 get the same sort of electronics into the object. Then 0:18:58.080 --> 0:19:00.800 you start to think more about what does the future 0:19:00.840 --> 0:19:04.280 look like long term sicky years from now. Um, it's 0:19:04.320 --> 0:19:09.120 not just about creating nano printed scaffolding to grow tissue 0:19:09.160 --> 0:19:14.200 on or to use in other nano manufacturing parts. There 0:19:14.280 --> 0:19:17.639 is a real ability to say, create a robot that 0:19:17.760 --> 0:19:21.440 is at the nano scale and what happens then, well, 0:19:21.480 --> 0:19:23.479 then we have the idea that we have machines that 0:19:23.560 --> 0:19:27.480 can repair themselves. We have we have structures that can 0:19:27.520 --> 0:19:31.720 repair themselves, buildings that can heal, bridges that can build themselves, 0:19:32.160 --> 0:19:35.040 little tiny robots that can peek into your private life. 0:19:35.040 --> 0:19:36.720 We're talking about this the other day when we're shooting 0:19:36.720 --> 0:19:39.239 a video. Yeah, we were just saying that, Um, I mean, 0:19:39.280 --> 0:19:40.960 how do you combat that we have your own little 0:19:41.040 --> 0:19:45.680 army of nano robots system really of nanobots to protect 0:19:45.920 --> 0:19:48.960 your privacy and your interests. And we all kind of lit. 0:19:48.960 --> 0:19:50.840 We're just all crawling with them like fleas that we 0:19:50.920 --> 0:19:52.679 just and maybe they're also programmed to cut our hair 0:19:52.720 --> 0:19:55.560 and to groom ourselves, which is nice, it's lovely. Um. 0:19:55.600 --> 0:19:58.359 Other considerations. We talked about this when we talked about 0:19:58.400 --> 0:20:00.280 the atropasy, and this is the idea of we are 0:20:00.320 --> 0:20:03.560 now in the age of man and that human activity 0:20:03.600 --> 0:20:07.600 has left a stratigraphic signal in the soil and scars 0:20:07.600 --> 0:20:11.160 in the earth, chemical signatures, etcetera. Yeah, and we find 0:20:11.160 --> 0:20:14.040 this an ice cores. Right, there's data retreat from glacial 0:20:14.080 --> 0:20:17.040 ice cores that show the beginning of a growth in 0:20:17.160 --> 0:20:22.320 atmospheric concentrations of several greenhouse gases, in particular CEO two 0:20:22.359 --> 0:20:26.200 and c H four. And the starting date actual actually 0:20:26.560 --> 0:20:30.720
