Description
Build a plastic recycling machine to make 3D printable filament for 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 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.
Contents
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) ?
Also we will have to be able to dig holes to put the temp sensors inside. |
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.
This will be controlled by a thermostat (when the tx is above a defined point we shut it down). Find a way to attach this (high-temp resistant tape ?) and isolate from the outside. |
Bought 3.048m of G28 nichrome wire. |
| 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 |
Resources
Extruders
I'm guessing we should build something in between - not too simple but not too expensive either.
Misc
- Color filament
- Filament recycling detailed research paper (noskill)
- Broyeuse extrudeuse domestique (noskill)
Schedule
- 2013/11/22 - Starting experiments :)
