12-pack extruder gear kit

This 12-pack contains hardened steel extruder gear kits for Bambu Lab X1 and P1 series printers. Each kit includes dual gears with DLC nano coating, an aluminum handle and a POM gear. The integrated shaft design reduces eccentric rotation during filament feeding.

Suits carbon-fibre printing; not for other printers

Owners of X1, X1C, X1E, P1P or P1S machines who print abrasive filaments such as PAHT-CF or PET-CF gain longer gear life and smoother extrusion. Printers outside this model range cannot use the kit, and users printing only standard PLA may not need the upgraded hardness.

DLC-coated hardened steel gears

The defining specification is the DLC nano coating on hardened steel gears, which directly determines wear resistance when processing carbon-fibre reinforced materials. Without this coating the gears would wear quickly under abrasive loads.

Questions about this item

Which Bambu Lab printer models does the KYF-3D-324 gear kit fit?

The kit is compatible with Bambu Lab X1, X1C, X1E, P1P and P1S 3D printers.

Will the hardened steel gears still feed standard PLA and PETG without grinding?

Yes, the double-bearing helical gears handle basic filaments such as PLA, PETG, ABS, ASA, PC and TPU as well as carbon-fibre composites.

How can I confirm the extruder is running correctly after installing the kit?

Watch for smooth, consistent filament flow with no skipping or grinding during the first test print.
