3D Filament Pelletizer Powered by Drill by wahada

At first sight it might seem odd to make something that chops up valuable 3D plastic filament into pellets. However, if you have a Filastruder it can be very useful in making master batch colorant pellets from natural resin and powdered pigment. One can also make colored pellets for a bench top injection molding machine. Recently I replaced my old dead 3D printer that used 3 mm filament with a new one that uses 1.75 mm filament. I was stuck with 3 rolls of 3 mm filament that I could not use in the new 1.75 mm 3D printer. With this pelletizer I was able to chop up one of the 3 mm ABS reels, 1.6 pounds, into pellets in 40 minutes. Now I can use the pellets in the Filastruder to make useable 1.75 mm filament. I also pelletized 1.75 mm filament and it worked just as well. So the 3 mm hole will accommodate both 3 mm and 1.75 mm filament. There is no need to drill a another bolt with a 1.75 mm hole.This is the second version of the pelletizer. The first one was very similar but had an all metal frame that required machining, welding and brazing. This new version only requires a 3D printer to make the frame. To be honest I was not sure that an ABS plastic frame would be strong enough to do the job. I am pleasantly surprised how rigid it actually is and how well it performs.
