1、APPLICABLE MODEL: This extruder kit is suitable for CR 10, for CR 10S, for Ender 2, for Ender 3, for Ender 5 series, check the model for better fit! 2、APPLICABLE MATERIAL: This extruder kit can be used to print consumables such as PLA, ABS, PETG, PU, PP, PC, Nylon and other standard 1.75mm diameter consumables. 3、LARGE TORSION EXTRUDER: The extruder is light in weight and small in size, but can achieve greater transmission ratio and torsion, provides better printing effects. 4、EXCELLENT PERFORMANCE: With this all metal extruder, you can have more consumable options when using a 3D printer. At the same time, a larger nozzle wheel increases the grip of consumables, reduces skidding, and a larger transmission ratio increases torsion, thereby increasing the thrust of the nozzle and improving printing quality. 5、ALUMINUM ALLOY, HARDENED STEEL MATERIAL: The shell is fully aluminum alloy oxidized, the reduction gear is POM CNC processed, and consumables are extruded. The wheels are made of hardened steel, and the aftertreatment is quenched and plated.
