Bambu Lab Auxiliary Extruder Gear Assembly – X2D - FAE051

Product Description

Bambu Lab Auxiliary Extruder Gear Assembly – X2D (FAE051) is an original replacement part designed for the auxiliary extruder of the Bambu Lab X2D 3D printer. This is a complete extruder gear assembly that ensures precise and reliable filament feeding into the right, bowden hotend.

During long-term use, gear wear, filament slipping, or grinding can occur, leading to under-extrusion or nozzle clogging. Replacing the entire gear assembly is a quick and effective solution that restores consistent material flow and print reliability from the auxiliary nozzle.

Main Features

• Original Bambu Lab part – full compatibility with the Bambu Lab X2D 3D printer.
• Complete extruder gear – includes gears for filament feeding in the auxiliary extruder.
• Designed for the auxiliary (right) extruder – part of the system that supplies the right nozzle of the X2D in dual-nozzle mode.
• Restoration of reliable filament feeding – eliminates slipping, grinding, or uneven filament extrusion.
• Easy replacement – designed for user maintenance according to the official Bambu Lab guide.
• Suitable for technical and support materials – ensures stable material flow for supports, interface layers, and multi-color printing.

Use and Benefits
