 The lab has a system for shredding and recycling 3D printing filaments. We're currently set up to process PLA and PETG.

 You can fill the hopper and leave it running, it will automatically turn off after a while of it detecting there is nothing to shred.
+===== Shredding plastic bottles =====
+You can shred plastic bottles and other products after you have washed them with soap and warm water and dried them. Leave a note on the container for others to know what settings to use. The shreddings can be used to [[https://www.youtube.com/watch?v=8HVjUGZM_cQ | melt into a sheet]], then [[https://www.instructables.com/Upcycled-Plastic-to-Laser-Cut-Boxes-to-Store-More-/ | laser cut to make things like boxes]]. Steph also has a small injection moulder in his office. Costa might be interested in an injection moulding project too.

+(The documentation is conflicted about if PLA should be ran with soft or hard mode, both seem to work. Update the wiki with settings you find work better)
 Add raw pellets 40-60% by weight. 100% recycled is also possible, but worse quality, not yet tested in the lab.

 "Custom" allows you to set the winding speed manually. The control isn't fine enough and would need to be tweaked in firmware to be useful.
+The extruder can work for a maximum of 4 hours at a time, cool it down for 2 hours before turning it on again.
