The extrusion gear has undergone post-treatment quenching and nickel plating process, which is more wear-, prolongs service life, and improves printing quality. With this all-metal extruder, users can have more option for consumables when using 3D printers. This LITE extruder is mainly suitable for CR10 / -10S / / V2 series models. The larger extrusion wheel increases the grip of consumables, reduces slippage, and the larger transmission ratio increases the torques to increase the thrust of the extruder.
