== Parts needed ==
* Tube (or and 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
* Extrusion nozzle
* Cooling system (air/water/oil ?)
