We just received our filastruder and are in the process of assembling and testing this filament extruder. The filastruder takes raw ABS, PLA, HDPE, and various other polymer raw materials, and extrudes them into a nice 1.75mm or 3.0mm filament for 3D printers. We hope to include this device, or another open-source variant, in our rapid-prototyping and manufacturing kit. The kit will include a filament extruder, 3D printer, and 3D scanner. Options will include the tools necessary to use recycled raw materials for filament, a compact CNC mill for PCB milling, and an inkjet printer capable of printing circuits onto nearly any substrate using silver nanoparticle ink .
