Topic: Inconsistent extrusion when making Polypropylene filament
I am having difficulties trying to extrude polypropylene filament. I'm having cooling issues, inconsistent extrusion, and potentially jamming. So far I've tried extruding from 175C-205C with no luck. Ive also tried moving the nozzle fan around and am printing a fan duct to get more precise cooling.
For anyone that's made PP filament, what temp did you find best? I'm using a talc filled PP, so it'll need to be a bit hotter, but a base would be helpful.
Also, did you run into problems with effective cooling, inconsistent diameters, or jamming?
I'm running a 45 degree setup with a filawinder.
Thanks!
