The double gear rotation design locks the filament, which is beneficial to improve printing quality and reduce filament slipping, high-speed extrusion or retraction, better pressure to push the filament into the printer, less easy to lose steps, faster printing speed Compatibility - Double gear mk8 extruder, perfect replacement for 3D printer CR-10/ CR-10S/ CR-10S Pro/ Ender 3 (initial version)/Ender 3 v2/Ender 3 pro/Ender 5/Tornado, etc. 1.75 mm filament (Set only for 3D printers with motor shafts exceeding 20mm, please measure the shaft length before placing an order.) Stable and Durable - All metal aluminum alloy, high quality double gear extrusion, compared with ordinary plastic drive, this high aluminum metal filament extruder is stable and durable.
The idler gear has been upgraded with a brass washer added between the stainless steel gear and the aluminum housing, so the gear does not collide seriously with the housing, which helps reduce stock extruder wear. Adjustable Spring - The tension of the extrusion spring can be adjusted by tightening the screw, which greatly improves printing accuracy and paper feeding problems. Strong extrusion end spring enhances feeding strength and ensures stable pushing of filaments into the hot end of the printer.
Suitable for most types of filament, such as ABS, PLA, TPU, PTEG etc. Imported Materials If you need some installation help, there are video introductions online, and you can seek our technical help at any time.
