  I run a makerspace at a local university. I have been trying to work out a grant for the other recycler you showed. This one here is within our budget! Thanks Stefan!

  I’d love to see an experiment showing how repeated recycling affects strength and printability.

  You lost me at “only 600 bucks”

  when 600 bucks is more expensive than your printer 💀

  I worked in an industrial extrusion plant, this is just a way scaled down version of our recycling process. Set aside scrap, throw into the granulators, put into bags, feed back into the line at 80/20 virgin powder to regrind. A couple tips if you want it to go smoother and produce more.<br>If you pulverise some of the regrind into a fine powder and mix with the chunkier regrind, the extruded product will be far more consistent. You can attach a magnet to the side of the hopper and that will pull out any metal before it has a chance to clog the filter. Use a blowing agent like hydraxine or similiar via a suspended dropper and you can drop the screw speed and temps to almost double your final extruded product at the cost of density. If you want to get super in the weeds then you can drill a hole near the end of the screw barrel and pull a vacuum on the melted material &nbsp;to effectively eliminate any contamination.

  This is a HUGE step in the right direction. I&apos;ve been so confused as to why there aren&apos;t any solutions to shred and re-spool 3D printing waste that are consumer grade and priced. I&apos;d love to buy a system to recycle my PETG and PLA waste, but it&apos;s way too expensive right now.

  @CNCKitchen Have you heard of the INFiDEL by Thomas Sanlander? Its an inline filament sensor, and if the designer of this actually added the sensor to this project, it would be more autonomous. It is capable of feedback, and He said that if someone wanted to, it could be used to have a variable extrusion rate during printing, based on the filament diameter. that basically means your filament tolerance doesn&apos;t need to be as good. Here is the video Title: Make your own inline filament diameter sensor (under $5)!

  TeachingTech just released a filament shredder/chopper, which would be really useful for you to re-pelletize some first stage filament! That should give you uniform pellets that work much better for your filament extruder.

  $700 for a DIY kit is a lot of money... especially since you&apos;re printing 1/2 the stuff yourself.

  This is a very nice machine, I hope they will become as affordable as printers.

  Imagine paying 650$ and not getting gummy bears.
