== Description ==
Build a plastic recycling machine to make 3D printable filament for the [[Ultimaker]] and other people's printers.
* Ventilation preferable for ABS

|-
| TubeMain frame| Part where Main part holding all the material will flow troughparts together. Which material should we use ? (Aluminium/ (Stainless) steel) ?Also we will have to be able to dig holes to put the temp sensors inside.| Done| Got ~1.5 m of dia. 20mm aluminum / 1.5mm thickTODO
|-
| AugerCoupler| Screw pushing Holds the materialmotor rotor and the screw together| '''Needs update''' with new motor rotor diameter (8mm)| Just bought [http://www.ebay.com/itm/20mm-Long-Combination-Wood-Auger-Drill-Bit-Carpenter/310775630556 one of those] on EbayTODO
|-
| Motorholder| Makes stuff moveHolds the motor (duh.)| Needed'''Needs update''' with 3 holes mounting instead of 4. Thickness needs to be checked for usage with new motor| TODO
|-
| Heating elementScrew holder| Nichrome wire ? Ceramic heaters ? Quite cheap on ebay.This will be controlled by a thermostat (when Aligns 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 screw with the tube (rear, middle and nose for example).| Got 1 DS18B20|-| Extrusion nozzle| Transforms the heated plastic into a regular filament suitable for the printer.| Needed|-| Cooling system| "From liquid May need more grease to solid in a trice !". Air/water/oil ?reduce friction| NeededTODO
|-
| Tube
| Brings the plastic pellets/parts into a heated nozzle. Makes plastic filament (theoretically). Also the nozzle is exchangable with other nozzle models to allow various diameters of filament to be made

=== FilaWinder ===
Winder for extruded plastic. See [https://www.youtube.com/watch?v=uWDkBzS0XFI this video] for explanation.
Source files on [http://www.thingiverse.com/thing:174383 Thingiverse], and assembly instructions [http://solidoodletips.wordpress.com/2013/10/15/winder-2/ here]. They sell these for 159$ but seeing as we can 3D print many parts at fixme and laser cut other parts at PTL, total cost should be less than a 3rd of that.
== Resources ==
* 2014/01/17 - Added a metal top on the end with a 3mm brass extrusion nozzle soldered to it. Next step is adding motorization and automation (i.e. temperature regulation)
* 2014/01/30 - A more polished version of the metal parts will be made by [[User:noskill]]'s school polymecanics. The heated part and the nozzle will be removable.
* 2014/03/10 - Received the stepper motor and the arduino motor shield. Now the mechanics will make a first prototype of the machine in a few days. Also tested the temperature sensor under "real" conditions (~200°c) and worked perfectly.
* 2014/04/01 - The prototype is done ! And it's not even an April fools joke !
* 2014/06/11 - The motor used is not powerful enough in the current setup. Next step is to try adding a screw trough the rotor to get more torque and eventually to buy a new motor (DC, stepper ?).
