If there is a better (more exposure/more appropriate) place for my post please let me know. I purchased components recently to build a mini pellet extruder. I'm thinking it should work for melting and extruding powder which is the plan. It's branded as Funssor and similar to this one branded as a Polished3D The difference is the "barrel/heat sink" should be brass with the version I purchasedby brianmh13 - Mechanics
That's what I thought. I imagined it's detrimental to thermoset types of polymers. To what degree though would be interesting to determine.by brianmh13 - Polymer Working Group
Ok that's an interesting piece of equipment. I have been trying to "think outside the box" regarding plastics and how to develop new processes for producing material such as filament or print heads that can utilize new materials. The specific material/process I want to develop would involve using powder form plastics but not in the same way as SLS. I'm quite certain the equipment I would be uby brianmh13 - Polymer Working Group
Would it be possible to use thermoset resins such as epoxy and polyester in an heat/extrusion type printer say with polyester or epoxy powder in a screw type extruder? Obviously temperature would need to be higher than thermoplastic to extrude but would be possible? What about material strength after such a heating/cooling cycle(s)?by brianmh13 - Polymer Working Group
Diyouware if you can incorporate a high volume of fibers such as fiberglass into the extrudate then you would have a very desirable process/machine.by brianmh13 - Polymer Working Group
Has anyone been successful with producing ABS powder.by brianmh13 - Powder Printing and Selective Laser Sintering
