3D Filament Pelletizer Powered by Drill

thingiverse

The pelletizer, a handy tool for transforming valuable 3D plastic filament into pellets, is particularly useful when combined with a Filastruder. It can create master batch colorant pellets from natural resin and powdered pigment or colored pellets for bench top injection molding machines. Recently, I transformed a 1.6-pound roll of 3mm ABS filament into pellets in just 40 minutes with my Filastruder. The second version of this device uses a 1-inch Forstner wood boring bit as the chopping blade and can handle both 3mm and 1.75mm filaments without needing additional drilling. It requires only a 3D printer for its frame construction, making it an accessible and efficient solution for recycling or repurposing filament. The build process is detailed in the provided instructions, which also explain how to properly drill the 3mm hole in a bolt, the importance of bolt grade selection, and the best practices for assembling the pusher gear. Additionally, a YouTube video showcases this pelletizer in action.
