Shred-Buddy3D Turns Plastic Waste into Pellets for 3D Printing

The Germany-based team of Venture-Bit has developed a multi-material pelletizer and cutter, that shreds plastic waste into pellets. These pellets can then be used to create filament for 3D printing.

Shred-Buddy3D securely cuts recyclable plastic objects such as plastic bottles, leftover 3D printer material, cable ties and others into granules that can be used with a 3D printer or filament extruder. Due to recycable materials coming in many shapes, a quickly swappable system in form of various slide-tubes has been implemented. The self-developed stepper motor controls allows for adjusting the feed rate of the individual material. The speed can be continuously regulated via a rotary switch, while forward, backward and stop functions have been integrated as well. The main body of the device consists of 3D printed parts and all mechanical parts are of good quality. The shredder-element consists of a sharp HSS drill, known for its long durability. Additionally, the bottle slicer equipped with a standard cutter blade can be easily fitted.


Venture Bit offers two versions of Shred-Buddy3D – one that works as an attachment for a drill press and another as a support structure for a cordless screwdriver.

You can support the project on Kickstarter. Pledges for the Shred-Buddy3D start at € 130.
