Revision as of 01:22, 22 April 2020
Basics
- A Device for making Plastic Pellets or Plastic Flakes into Plastic Filament
- Can then be used in an FDM 3D Printer
- Also allows recycling plastic into filament with a proper shredder system/workflow
- Total Cost ~400 USD (skimmed bom?) ~16x 1kg 25 USD Filament Spools until it breaks even
- Filament Material Properties vs OTS Filament (needs research and/or dedicated page)
- Needs a bit more organized for new people looking for info on lyman, perhaps a geneology page?

Marcin,
Your work appears to be very interesting.
I don't visualize my being involved in your workshop as I am now 87 years old living in Enumclaw, Washington.
My latest Filament Extruder, Version 6 is the only extruder I am now supporting. It is my favorite extruder and all my filament is now produced with the three I have made. It extrudes 3mm (2.65mm) filament at about 1/2 lb/hour with the gear motor running at 25 rpm. The motor is rated for 33 rpm but under load it only goes about 25. . A faster gear motor with about 100 kg-cm of torque may give 1 lb/hr. I get a filament that varies not more than .05mm with the extruder wall mounted.
This extruder is posted on Thingiverse and is open source CC share alike. The posting includes a BOM. Also there is a video on YouTube.
