* Recycle failed/old prints and extruded plastic
* Recycle other plastics, such as PET bottles(caps), etc
* Experiment with new colors and materials
* Ventilation preferable for ABS
== Parts needed ==
* Tube (or a rubber stator if we choose the PCP option)
* Screw to move the material trough, like an Archimedes screw (where can we find that ?) but preferably a [https://en.wikipedia.org/wiki/Progressive_cavity_pump Progressive cavity pump] to have a constant flow, low shearing and perfect for viscous material transport).
* Pretty High torque motor
* Heating element (nichrome wires ?)
* Extrusion nozzle
* Cooling system (air/water/oil ?)
