In an effort to recycle waste prints, I had previously used a garden shredder and modified paper shredder together with some success. It could only handle thin pieces, however, so I had been planning a bigger, better shredder for some time. When I found the Precious Plastics bazar, it became feasible to put one of these machines together without too much time commitment.

Driving my shredder box is a 500kg garage winch, partially disassembled. It has more than enough torque for the job. The weak link is the coupling between the two, and although I have it working for now, it’s going to need further improvement.

Performance is outstanding! I can crush pieces I designed to be bulletproof, such as 60% infill, thick perimeter parts for the MPCNC Lowrider 2. You can’t do too many pieces pieces at once but if I shred as I produce waste it will be fast and efficient. The smaller particles melt in my oven in a much faster and more uniform way. I'm planning to mill and laser cut some parts, but ultimately want to make my own filament. If you want your product featured, get in touch.

I know not many will follow this at home but I feel passionate about this project and want to do what I can to document solutions to a significant problem.
