BIQU Upgraded Direct Dual Gear H2 V2.0 Extruder 3D Printer Part Drive Feed for Creality Ender & CR Series Printers, Anycubic Mega S, Geeetech Printers and Prusa I3 DIY Kits

【Advantages of H2 Extruder】 Retain the advantages of Direct extruders,The control of feeding is more accurate than remote extrusion and more precise back pumping.What’s more, the torque requirements for extruded stepper motors are comparatively low, and the material exchange is convenient 【Overcome the shortcomings of heavy Extruder】Usually the extruders of 3D printer is quite heavy,especially the dual-head printer, which has a large inertia in motion and is relatively difficult to accelerate deceleration, so it have to use a lower printing speed to ensure accuracy. But our H2 extruder with a light weight,which can solve this problem easily. 【ultra-strong torque by Multi-gear Feeding】Through multi-gear transmission, reached a 7:1 torque transmission ratio, ultra-strong torque 770mN .m. 【Low Roughness】The smoothness of the inner wall of the heat break and nozzle is Ra0.4 level, which is effective against clogging. 【High performance of heat dissipation】Stream-type thermal structure for ultra-efficient cooling.
