The assembly mechanism of Anycubic Kobra 3 Series / Kobra 3 Max extruder components is a direct drive system with a dual gear, responsible for feeding, retraction, and precise measurement of the filament towards the hotend during high-speed printing (up to 600 mm/s). This model includes a hardened steel gear system, integrated stepper motor interface, a spring-loaded tension rod mechanism, and a built-in filament cutting mechanism used during multi-color filament cleaning with the ACE Pro system.

• Dual Direct Drive Gear: Uses hardened steel gears with high reduction gearing to provide high torque, preventing slipping and grinding of the filament during rapid acceleration.
• Integrated Filament Cutting Mechanism: The built-in cutting mechanism cleanly cuts the filament above the heat break during automatic color changes and retraction sequences.
• High Volume Flow Performance: The optimized gear geometry ensures smooth pushing of flexible (TPU) and rigid high-temperature filaments (ABS/PET-CF) without bending inside the feed channel.
• Adjustable Tension Mechanism: Features an adjustable tension screw for precise adjustment of the gear grip strength depending on the hardness and flexibility of the extruded material.
