Creality Ender 3 S1 Pro Metal Extrusion Mechanism Kit, 3D Printer Parts Metal Direct Extruder Kit for Ender 3 S1, S1 Plu

Metal Extruder: upgraded metal double-gear extruder, with greater extrusion force, more smooth and accurate wire feeding, strong and durable.

Direct Drive: Compared with Bowden extruder, the direct drive extruder is compatible with more filament materials and is more suitable for printing flexible materials.

Large Torque, Extrusion Force Up to 80N: The use of gear with 3.5:1 gear ratio which perfectly matches with motor makes extrusion foce up to 80N(depending on filaments). More precise control of feeding withdrawal.

Dual Gear Feeding, More Stable Printing: The double-toothed structure does not damage filaments, feeding it more reliable and stable.

Adjustable tension: The tension allows you to fine-tune the pressure exerted by the drive gears onto the filament according to your perferences which helps to print more exquisite models.
