 Okay, I am Dana. I'm going to be class on 3D printing. So 3D printing, what it is and what it's good for. I'm not going to go dive deep into this stuff. There's somebody who has to do it. There's somebody who has to do machines out there. I'm going to show you how we do it down here in the summer or night. Let's start with Chuck Holt. Chuck Holt was the guy who invented stare lithography back in 84. Basically what that is is a way, software driven way to take a 3D object and to slice it very thin so that it can be put into a different type of machine like a 3D printer and it will extrude each layer and rebuild the exact same physical 3D image. He also developed a steel format that we use in most of our machines and before this development, most of our piece procedures were done for removing material from a larger piece and making your final piece. I was trying to think of another way that wasn't using, you know, piece removal or subtraction, but even if you were molding something like iron, like a block, an inch block, you have to have a forwarding model before you make the sand past and then pour metal in there. But anyway, it's a good deal. This process is called additive manufacturing. So what can you do with 3D printing? Well, how much area does it make? Things, plastic things, but also we need to predict data visualization. You can use like this because I love like this. But, you know, like this picture, I saw it from the internet because that's what we do. And this is the most used keys and it's a 3D printed image of how, which keys press the most often. And I think that's pretty cool because, you know, instead of just manufacturing something, prototype of something, you're actually using a device to produce something visual as opposed to just having it on a screen. So it's pretty cool. And then prototyping, obviously you see me over there. It's my CNC machine. I am trying to make this. This is the death combat I made for last year. This is mine. I printed it off. This is the gold version. This is a really happy bow. And so for prototyping, I made plastic ones and I gave them out to my crew. But also I want to make metal ones, you know, so I prototyped it into plastic and I saw, hey, this is pretty badass. So now I converted the G code and now I'm just trying to set up the machine, right? And, you know, manufacturing with the CNC machine is time consuming because it's very tricky. And you're breaking bits up, right? And I'm not going to say that I break bits all the time, but someone I know breaks bits all the time and they're pricey to, you know, throughput. So near and dear to my heart is, you know, amputations, you know, you can use a lightweight plastic to, you know, prototype and then actually develop and design body parts. So, you know, a lot of people in Afghanistan, Iraq, the Boston Lakes, my buddies, and also the Spurton Palace. You know, this guy, his quality of life is so much better just because someone decided to print out a kidney bean shaped prosthetic, cut his pieces, whatever. And I just think this is cool because it's all about biomics. I love that stuff. So, oh, and this is also cool. Back a couple years ago, I used to do brain surgery and it was in one of our theaters of war. And, you know, when the guy got shot in the head, basically we had to go in there and we had to cut out his skull, you know, because it's got a bullet hole in it now. It's not good for anything. So we pulled it out and created the brain, you know, covered up all the non-viable tissue. And, you know, but what we had when we pulled out this skull was a hole. And, you know, we try to save as much as natural material as possible. But, you know, seeing this and, you know, I could just go in there with my little calipers and measure his hole. And we bring the brain to our skull part. So I think that's pretty cool. So, manufacturing, right, we did, you know, data visualization, we did prosthetic and manufacturing. You know, it's kind of with prototype, but with manufacturing you're actually making an end product. So you have all these sectors of the economy or whatever you want to call it, facets of life. Medical, like you saw, clothing, people are pretty chews. We've got buildings, different type of 3D printers that produce concrete and produce a building in, you know, a cook and cutter building in, you know, a short amount of time and without any, you know, human interaction. Well, not really interaction, but helping or human labor. I expect, you know, food, sure, I'm not sure how it tastes. You have vehicles that's on the cover of the New Make magazine. You've got kind of Prister-free car. Nature, this is pretty cool because it's about, you know, redesigning coral reef. So you can, you know, repair damage, you know, if the reef's been damaged by boats or, you know, human shenanigans, then it replaces and then it rebuilds the whole ecosystem in that area. And then obviously here, you know, I am a soldier retiring, but, you know, weapons. It's a very, you know, it's a useful purpose for some type of thing. But my favorite one here is art. I mean, just for the fucking beauty of creating something that you can actually touch and see. So processes. I'm not going to go into the secret all. There's our, there's a couple. There's five lists here. But the top one, extrusion, is something we're going to talk about because that's what I use. That's what most of the maker boss and replicators and everything else. That's what, that's a system that you use. So it's a few step-position modeling and the materials used are thermal plastics. I use the ABS plastic for anything that we may be doing. So you can extrude, you know, soften it up, extrude it through a little pinpoint nozzle and then re-create stuff. Thanks to Chuck Hull with his serinophoxy, you know, you can, you know, duplicate it. So started back last year when DC7-i was going to run this badass Wi-Fi Geo locating contest within the whole Colorado Springs area. I figure, okay, why can't I just design a ring even though it's not? There's no cipher on it. But split level ring, you know, the top spins one way and the bottom spins the other way. And just have something cool. It's like a, hey, thanks for showing up. Here's your badass ring. But, you know, that fell aside and it doesn't work and stuff. So this is the new ring I developed. I'd say probably last month, December, I wanted to give this presentation to my crew and I wanted to bring them rings. But, you know, shit happens. Three printer didn't like it. But anyway, I found out that I did print one of these and it was just too small. I mean, it was badass, but it was just too thin. It would have been a good pinkie ring for girls. So I totally retuned it. But, you know, this is the trial and tribulation I had to go through. Like this right here, my machine is a ported stick at the MC. And, I mean, it's 300 degrees. It uses two materials, molding material and support material. And this is an envelope material. But anyway, you know, it's still warming up at 304 degrees. Come on, really? And I'm just taking my hand and they're trying to replace the tips and nozzles. And it's just a big pain in the neck. I'm not going to get it into the whole thing. But I will give a class on how to have a step, how all the processes like used to get to this point. But that was a big failure. And actually, I'm kind of glad it was a failure because the ring shape. So, this is a really, really new ring. Okay? After I saw how that ring was printed, I said, okay, I want a more manly ring. And so I made it wider and made the smiley, swollen crossbones guy fatter. And you know what? My machine fucking loved it. She printed out 20 or so different. I got 6.5 all the way to size 12 and a half step. And it's bad ass. Everyone likes it. Let's see it. And the detail is it will blow your mind because even though you can't really see it on this picture, you will see it in real life soon. But you know, that high resolution is phenomenal. I'm pretty happy with it. This is my dog. I take him everywhere. He's not here right now though. That's him just chilling around because you know, this whole process, it's not like, oh, you know, you're going to come up with a design. I use AutoCAD because I love it. I switched from 2013 to AutoCAD 2015 with this new ring because I wanted to, you know, I'm a student somewhat and I got the software and I wanted to, you know, use it. So I taught myself AutoCAD 2013 with the new ring. And the process does take a long time. You've got to cat it and then you have to, you know, transport it into, you know, with a USB thumb drive or whatever, into the other machine so it can convert it into the STLs and the 3D printer will print it. But, you know, my dog is just chilling because he likes hanging out in my office. This is the baddest place. This one, Rofi. He's everyone loves robots and I give him a bipod robot. These are all the parts. I'm just waiting for some servos and everything else to come in so I can build them together because who the hell doesn't want this? Just wandered around all over fucking places. Walk my dog, maybe, or not. Dog maturity, dog Tesla. Rocks. Like, why the hell would you want a fucking rocket with big rocks? So, I had rock here. Does anyone need a picture? Does anyone? Fucking, I don't know, 70 pounds. You can locate them like this. Very light. We need something like this. It's a 3D scanner. Next engine, right here. And we can replicate rocks. And you might say, well, why do you want to replicate rocks? Well, sometimes in the wild, we need to have rocks with, I'm not going to say video cameras or audio devices, but it could be helpful. So, in my shop, we also do molding. This is up some mold material. We have a vacuum extractor so we can do hollow molds. And we can just put stuff in there that we want to put in there for whatever reason we want to do it. So, we got rocks. And what else is there? 3D printing is pretty badass. You know, I was forced to learn AutoCAD back in 2001, 2002. And I kept up with it. And I wrote some list programs and whatever. So, next class, I'll give a little bit of introduction to AutoCAD. I'll see if I can get a free shareware version of AutoCAD or SketchUp or whatever. And go through a couple of classes like that. But that's about it. I didn't want to go too deep, but this is something I love. I love creating something so unique and original. So, thank you.
