There are two heads to allow a filler material to be laid down as well as the plastic. The build base then moves one increment down, the second layer is extruded, and so on. The machine prints layer by layer to form a solid object. At the top of the frame there are two write heads that move horizontally (driven by toothed belts and two more steppers) extruding a thin stream of molten plastic to form new layers on the build base. A flat build platform moves vertically in that frame, driven on screw threads by a stepper motor. RepRap etiquette asks that you use your machine to make the parts for at least two more Darwins for other people at cost, as well as using it to make whatever you or anyone else on the internet can think up.ĭarwin consists of a frame made from rods and printed parts.
