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
This replacement part is recommended in the following situations:
- repeated filament feeding errors from the auxiliary extruder,
- visible damage, wear, or contamination of the gears,
- frequent problems with under-extrusion, layer skipping, or irregular flow of material from the right nozzle,
- service maintenance of the X2D printer after long-term intensive operation.
Regular extruder care and timely replacement of worn parts helps maintain the top print quality that the Bambu Lab X2D is known for, especially in dual-material or dual-color printing.
Compatibility
- Compatible model: Bambu Lab X2D
- Location: feeding mechanism gear of the auxiliary extruder on the back of the printer
Not intended for other Bambu Lab models (e.g., P1, A1, X1, H2D, etc.).
