Grinding PET Plastics Answered

Hello,

I have recently been working on shredding PET plastics (#1 recycling symbol), to recycle the plastics into 3D printer filament. I have been struggling with finding a reliable and inexpensive method for grinding or shredding the plastics. The granules also need to be fairly small.

Please share any thoughts you have!
Thanks!

I'll have an Instructable on that coming soon, but I do it mosts with a utility knife and scissors.

Note that I have tried a meat mincer, and it doesn't work. RIP electric meat grinder :(

Some of us have been talking about this for seven years.
