About Direct Extruder Kit: 1. lower torque requirements on stepper motor, reducing filament retractiion. 2. Feed-in more evenly than remote bowden extruder, lowering probability of cloge. 3. fit for printing with flexible filament, optimizing printing effect.
Upgraded Kit: Direct extruder kit offered by official for Ender 3, Ender 3S, Ender 3 Pro, support 1.75mm diameter filament, especially for flexible filament like TPU
Smooth Feed-in: The direct extrusion structure needs lower torque requirements on stepper motor, reducing the possibility of nozzle blockage when retracting filament
Greater Compatibility: Compared with bowden extruder system, more fit for printing with PLA, ABS and other flexible filaments
Strong & Sturdy: This direct extruder kit is all metal structure, durable and wear resistant
Easy Assemble: Longer connecting cable, tools, accessories and diagram instruction, easy to assemble
