Description

Build an extruder to recycle and create new filament cheaply for Fixme's Ultimaker and other people's printers. An extruder is constructed from essentially two parts: a feeding mechanism, and a heater - chopped plastic is fed from a container into the feeding mechanism, which then pushes the plastic slowly through the heater to create the filament.


Goal

  • Recycle failed/old prints and extruded plastic
  • Recycle other plastics, such as PET bottles (caps), etc
  • Experiment with new colors and materials

Obstacles

  • Get a filament of repeatable thickness
  • More complex = more difficult
  • Ventilation preferable for ABS

Parts needed

Part Name Description State
Tube Part where the material will flow trough. Which material should we use ? (Aluminium/ (Stainless) steel / Needed (20mm internal diameter /)
Auger Screw pushing the material Just bought one of those on Ebay
Motor Makes stuff move Needed
Heating element Nichrome wire ? Ceramic heaters ? Quite cheap on ebay Needed
Thermometers Get the internal temperature in different places of the tube (rear, middle and nose for example). Needed
Extrusion nozzle Transforms the heated plastic into a regular filament suitable for the printer. Needed
Cooling system "From liquid to solid in a trice !". Air/water/oil ? Needed

Extruders

I'm guessing we should build something in between - not too simple but not too expensive either.

Why do we even have this section?
