Build an extruder a plastic recycling machine to recycle and create new make 3D printable filament cheaply for Fixme's the [[Ultimaker]] and other people's printers. First (optional) step of the process is to melt plastic parts (such as bottle caps, failed prints, packages) into plastic pellets. This can be done by putting parts inside a heating recipient having a hole at the bottom. An irregular thread of material will come out and be sliced into small pellets. Next step is to transform pellets or plastic parts (if they are small enough) into 3D-printable filament. This is performed by the extruder. An extruder is constructed from essentially two parts: a feeding mechanism, and a heater - chopped plastic is parts or pellets are fed from a container into the feeding mechanism, which then pushes the plastic slowly through the heater to create the filament.
