Bambu Lab X1/P1 - Hardened Steel Extruder Gear Assembly

Bambu Lab hardened steel extruder gear assembly FAE015-R for X1 Series and P1 Series printers. The drive and driven gears feed 1.75 mm filament into the hotend.

Compatibility and selection

Use this assembly to replace the internal extruder gears on a compatible X1 or P1 Series printer. It can also upgrade the P1 Series extruder from its standard stainless steel gears to hardened steel for improved wear resistance.

This is the gear assembly, not a complete extruder unit. Check your printer model before ordering; A1 Series printers use a different gear assembly.

Maintenance and installation

Inspect the gears for wear or trapped filament before replacement. Bambu Lab provides the removal and reassembly procedure in its X1/X1 Carbon extruder maintenance guide. Use the maintenance instructions for your specific printer model. Switch off and unplug the printer before working on the extruder.

Hardened gears improve resistance to abrasive filament, but the nozzle and printer must also meet the chosen material’s requirements. Browse Bambu Lab spare parts for compatible replacement components.
