Product material: metal + high density engineering plastic, aging resistance, wear resistance, light weight.

High precision CNC hardened steel internal parts can ensure smooth feeding during printing and achieve the best performance.

Strong compatibility, compatible with all open source 3D printers with 1.75mm diameter consumables on the market.

The transmission ratio is 3:1, the double gear decelerating mechanism can feed stably without slipping, and give more torque to extrusion. Support remote and short-range feeding, support printing TPU and other flexible filaments.

The fastening spring device allows the user to fine tune the pressure exerted by the feeding double drive gear on the consumables, so as to facilitate the replacement of consumables of different materials.
