 Okay, we're here with one of our other 3D printing exhibitors at Wolf 3D, who have brought some of their printers with them to show us. Hi. So could you just explain to us kind of the advantages of your 3D printer? Yes, so we're very, our whole kind of philosophy on our printers is materials. And we are creating printers that not only print in your normal PLA or ABS printing materials, but your more engineering grade materials like nylon, polycarbonate, PCABS. Some of your more high grade engineering grade materials, your strong materials that you can really use in functioning prototypes. What is it about your machine that allows you to print? So it's all about our print head. We're not using an all metal design which a lot of the companies are kind of gearing towards. We have a proprietary material in there that we're using to create a very small heat element in there where we can retract and extrude and keep that material at a very stable temperature and rate in there to feed correctly. We're also able to reach 330 degrees on the head which can withstand polycarbonate some of your high grade materials. Do you have a heated trim bed as well? We do, yes. Do you have a heated water trim bed? Yes. We're printing strain on glass. We have our own proprietary liquid that actually goes on the glass called Wolf Bite that we just came out with. That stuff prevents any kind of warping and it also is heat sensitive. So as soon as that part cools, the part pops right off and there's no fighting with your part getting it off the bed afterwards. So is this to improve the reliability? Improve the reliability and also resolution and the overall look of the part too. Okay. Do you know who your main customer is? I would say a very big industry right now is aerospace. We do a lot with education, especially with the STEM program and things like that. And then also a lot of just engineering firms and kind of the... It's kind of filling the gap between the large production grade printers and then the small desktop DIY printers. Okay. Do you want to show us some things that you... Yeah. So some of our of these engineering grade materials I'm talking about are the nylons which you see here. We have polyurethane which is our flexible material. It's a very good layer to layer bond. So this is a very strong flexible material out on the market that we actually develop ourselves. We're also doing things with nylon which I can take you over here. So this is another breakthrough we've made recently that we actually haven't even announced yet. So I guess I'm announcing it now. We're doing nylon with dissolvable support material. Okay. So this is a part before where we're using PLA actually to dissolve out of the part and then this is after. So we're getting very nice, you know, more technical geometric shapes that we can do now to dissolve the material out. And what solvents do you need to dissolve? Right now it's actually, it's a proprietary solvent but it's based on chemicals that are in Drano. Okay. So still household friendly but, you know, not completely non-toxic but... Okay. We have a lot of people that tell us that it's totally dissolvable in sulfuric acid. Got it. No, it's still pretty friendly. Okay. Another thing we can do with this dual head printer is not only print soluble material but we can do dual material. So here we have a soft material and like a hard ABS and that's done with our polyurethane also. Okay. Do you need two separate print heads to do that? You do. For this actual design here you could stop the print, swap out the filament and start it again but we can do the same type of thing with more complex geometry as well. Okay. This was actually something made by a customer. This was done on one of our very first kit printers. This guy is a very good customer of ours. He came back after a couple months and designed this beautiful Batmobile. It's all pieced together in sections. There was about 150 hours of print time. Okay. What is the build volume? The build volume on our printer is on the single head, it's 12 by 8 by 12. Okay. That's inches. And then on our dual head you lose about a half inch on the Y axis. So you have 11 and a half on the Y and then you have your 8 inches and then 12 inches high also. And you sell the materials? We do. We sell most of the materials. So here we have like our ABS line. We have polycarbonate. We sell the materials that we use a lot in-house and that's because we can now guarantee the quality of our materials in our printers and we don't leave people to kind of guess on what they should buy. A lot of the materials that are proprietary we still want to test and make sure they run in our printers so that we leave those options open to our customers as well. What's your most popular material? I would say the polycarbonate is a very big seller mostly in the aerospace industry. Okay, because it's quite unusual. It is. It is. Not many people do it. It's really because of our head design in that we can reach that high temperature that a lot of it can't reach. Okay, of course. Yeah. In aerospace is it still predominantly prototyping? Yes. You're starting to see the gradual move into low run production. I would say within the next five years we're getting closer. Okay. With FDM, FFF printing you're still running into the speed limitations. Yes, of course. I will. Thank you for your time. Yes, thank you. Thank you.
