Mini Double Shaft Shredder for 3D Printing Waste

As large-format 3D printing expands, laboratories and manufacturers are generating more oversized plastic waste from failed prints, prototypes, supports, and production offcuts. One recent customer inquiry involved shredding 1m+ 3D-printed parts made from ASA-GF, PC-CF, PC-GF, PEI-CF, and PETG. The required capacity was up to 250 kg/h, with typical volumes of 50–100 kg/h.

For this application, a mini plastic double-shaft shredder offers a compact solution for processing bulky, difficult-to-process 3D printing waste. Its low-speed, high-torque cutting system can break down large plastic parts without extensive manual pre-cutting, making it suitable for laboratories, additive manufacturing facilities, and small recycling operations.

The small shredder machine is designed for durability as well as compact installation. Its main frame uses a high-quality steel plate with stress-relieved welding and integrated machining, providing stability during long-term operation. This makes the mini shredder a practical choice for users who need reliable size reduction but do not require a full-scale recycling line.

For 3D printing operations producing 50–250 kg/h of plastic waste, a compact double-shaft shredder can provide an efficient first-stage solution while saving space and simplifying material handling.
