thingiverse
Human: 4 mm Screw Extruder prints 3D objects using plastic Powder (no filament!). Tested with Polycarbonate (PC) Powder at a temperature of 290°C; watch the video here:https://www.youtube.com/watch?v=13jkwoyeeak Download the 3D Fox Printer Controller for Android app from the Google Play Store here:https://play.google.com/store/apps/details?id=com.fox3d.controller Plastic parts are created with TreeD filament, available at http://treedfilaments.com/ This is a proof-of-concept design; unfortunately, a 4 mm screw is too small for everyday use (only works well with very fine powder) and direct-drive does not provide enough torque to achieve higher speeds. Update March 2018: a fully functional Pellet Extruder is now available; see https://www.thingiverse.com/thing:2821132 and https://www.direct3d.it
