Specification Brand : Aladrs BulletPoint1 : 【Wide Compatible】Extrusion Kit can be compatible with most 3D printers, such as Ender-5 S1,Ender-3 V3 SE,Ender-3 V3 KE,Sermoon V2,CR-200B Pro,Ender-3 S1,Sermoon V1,Sermoon V1 Pro,Sermoon D3. BulletPoint2 : 【Direct Drive Extruder 】Compared with Bowden extruder, the direct drive extruder is compatible with more filament materials and is more suitable for printing flexible materials. BulletPoint3 : 【Large Torque 】 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. BulletPoint4 : 【Smooth Printing and High Torque】3.5: 1 gear deceleration ratio, improved the squeezing performance is smoother at the same time, supporting smoother printing. The adjustable tension allows you to fine-tune the pressure applied to the driver's gear to the filament according to your preference, which helps to print a more beautiful model. BulletPoint5 : 【Durable and Stable】The use of a double-gear drive will not damage the wire, so it supports stable, smooth and accurate filament. Advanced all-metal design, exquisite, powerful and complete, effective heat dissipation. It weighs only 210 grams, a small elves.
