 Hey everybody, I'm here at MIRV 2021 and I stopped by this booth right here and I'm going to talk to Jeff courtesy of Thangs and Greengate 3D. Thank you guys so much for having me come to MIRV. Jeff, how are you doing today? I'm doing good. Good. Well, let the people know, who are you and what are you doing here today? Well, I'm Jeff Dimaj. I work on pellet-fed 3D printers. Here's a pellet head that I designed a couple of years ago. I've gradually improved it, improved it, so I've been making these different things. Here's a plane made from PETG, straight from pellets onto the part. That's awesome. So, a pellet-fed extruder is you're taking the raw resin, the pellets, you're putting it in the top and it's going through a process and extruding it straight out, right? That's awesome. What size nozzle are you running? Right now it has a 2.4 millimeter nozzle. I've gone from 1.5 to 3.5. That's awesome. I could just make what size I want. What are you printing on that you're getting this size prints? I built a tubular steel welded frame printer that I was going to try a bunch of different technologies on. I even had the thoughts of maybe putting a router head on it, so it's just meant to be really beefy, so it could hold something like this. That's awesome. So I've got to ask, these prints are awesome. There's an awesome PETG jet here, the coke bottle, the chair of course. So how did this start? How did you look and say, you know what, I need to make a pellet-fed giant extruder to print something like this? Well, it started before I got into 3D printing. I wanted to make custom parts for cars and I wanted to make like a custom hood or fenders or bumpers and obviously I'm not there yet, but so yeah, I mean that was like 2013, so I'm kind of gradually getting there, but I mean, so yeah, this is a stool I made just to try out the technology. Yeah, so like this is a viral, a base-mode spiral built, and then I have a structure inside screwed to a birchwood, plywood seat. That's awesome. It's inspired by ice cream chairs. Oh, okay. You go to ice cream parlors, yeah, I mean, I just, I took the same shape of seat and I just like, I want to make something that kind of look fancy. There we go. That's awesome. Well, that is really cool idea and I love that the inside has that structure and she's like, turn it over, turn it over. I love that. That makes it super rigid too. That's awesome. Yeah, we can stand on it. Oh, I bet. That's a solid piece now. The extrusion lines on this are pretty big. What size nozzle on this? I used two and a half millimeters on that. It's awesome. Everything here is one millimeter layers. Oh, okay. Nice. Yeah, you get that, kind of get the idea of like, okay, all the layer lines, yeah, that's one millimeter. That is awesome. So what, where are you going from here? So you have a giant tubular printer at home. Yeah. You brought in an extruder, not the whole printer today, but where do you go from here? Well, I want to make a bigger printer. I'm working on one that should be like six foot printable area. What? So, six feet? I have the design. That's awesome. Yeah. That's going to be awesome. I have the design. I just need to build it. Sure. That's going to be awesome. So, you use like a funnel for your resin to go into this? I'm working on that. Okay. That's part of the technology chain. Okay. So, when you're talking about manufacturing, handling pellets, there are systems that use vacuum and pressure to blow pellets to the hopper that you need to use it in. Yep. I think CME CNC has one of those. Exactly. So, they use the big trash can and a vacuum system. Yeah. Yeah. That's so cool. Well, I really appreciate you sharing with us. Yeah. This is so cool. Tell us once again, we're here at Merf. We're here at Merf 2021, even though they say 2020 on them. But, tell us again, who are you, where can we find you if someone wants to look this up? Well, I'm Jeff DM. I can be found on YouTube. I don't have the channel. Maybe I'd have to get with you on that. Sure, sure. But, I'm also on Twitter, JeffDEM. JeffDEM. Okay. I talk about 3D printer stuff so much there. That's okay. But, yeah. That's awesome. Thank you. Well, I really appreciate it. This is Jim right here from Merf 2021 with Jeff and an awesome extruder here.
