StoneFlower3D Launches New Print Head 3.0 for Ceramic 3D Printing

Automatic TRANSCRIPT

Just saw this interesting thing on. Three D. printing industry. I talked to you about it. Because you're the guy that's played with paste extruders earn stuff like that? This looks like there's a there's a kit that's about to hit the market that they talk about in this article made by a company. It looks like it's somewhere in Europe. Germany I think Germany where they they have a ahead that you can attach to any three D. Printer that will That will extra that will pull things through a vacuum tube and force it down into easily replaceable. Plastic extruder nozzles it. It looks like something that wouldn't be that hard to actually use and implement yourself that you think about well actually the first generation of this is the this is the stone flower three D. S. Extruder that we're talking about the first generation of it was actually I don't know if it was fully described as open source. But they had plans of it that you could actually build your own was built out of Small plumbing parts what I like about this Is Unlike others that I've seen it. You can have the material in a separate container flow to the the extrusion feeder to the extruder. Oh the ones I've seen in the past usually these big plungers yet. It filled up. And you're flying all of your material around the printer yet now. The thing to remember is that the The reservoir that feeds the material has to be pressurized Dork. So so the this These extruders have a little screwdriver in them that that forces the the material through the nozzle but they're actually relying on pressurized reservoir to deliver the material to the extruder this has proven to be the best combinations of the best design overall for extracting most paced stuff because you the ability to start and stop and the ability to retract. Which you can do that with you. Know there's a we've we've gone over before on the show but there's a bunch of different ways to extract pastes. One of the easiest ones is the is a syringe extruder. But the problem. Is You know with a syringe. You're pushing down the SYRINGE building up pressure and then driving the material out and then to retract riding back up on that cylinder and there's a lot of material in there that you're moving while you're doing that so it's not as responsive as you know we're used to with retraction on like an F. Damn extruder you'll have to really slow right. You have to go really slow and you end up with a lot of A lot of overshoot and a lot of you know material squirting out places. You don't want it because you're not able to control it that well whereas when you have a very small volume of material in this this Augur Screw Auger drive system You're able to You know pressure it drive it out the nozzle and retract it with much much more nimbly than than you. Can you know with with a large volume of material while so what I like about it? That it's nice and decoupled from any system that you might bolted onto sure in which makes it much much more amenable to someone who just wants to experiment with it a sculptor. Who May want to say? Hey I want a head start. Start from this basic design in after it's put out all the spray it with water and manually change. It sounds like it's got some really good potential I would sure love to play with it. Yeah it's Cool. And and the thing is you've got You know a NEMA seventeen which is probably the same thing that your printer was running anyway. So you could disconnect the the Nima Seventeen for your F- damn extruder and somehow adapt this to attach to Rhino. Whatever movement system. You're using I would say using old printer because you know paste It gets pretty messy. Yeah I I would go with a mental style so it's open kind of an open design. It's not all over the place. Yeah but it. But it's it's it's nice that their newest version of it. You can see a lot of evolution has gone through and I'll be curious to see You know not only how well it works. How well it lasts because when you're You know excluding clay clay abrasive Who that's right so you know you're depending on the type of clay body or extracting different particle sizes and stuff but over long-term Claes. Pretty abrasive material The nozzles that they're actually using vary depending on. How large a a diameter you want on. Sometimes they're they're using Like You know the small small diameter I would say plumbing fittings. But they're really more for like medical applications to being and stuff but they're plastic Obviously you know Easily replaceable. Yes own so. I don't think that's going to be that big of a problem. It's the internal stuff it's it's it's the Auger that is the expensive part. And and the the meshing between you know the the clearances between the author and the and the chamber that it has to fit in those have to be very very tight with polymers. We're finding that it's that nozzle the orifice itself and the sides of the office. Where all the where happens? I and that's what breaks down. I right so it's not gonna be that big of a deal on this kind of an extruder for that area. So maybe it'll be okay. We'll
