Increased Durability for Demanding Print Materials
The hardened steel extruder gear set from Bambu Lab is designed as an internal component of the hardened steel extruder unit. It consists of a driven and an active gear, which together ensure precise and reliable filament feeding into the hotend. Thanks to the use of highly durable materials, this assembly has a significantly better ability to process demanding technical filaments, such as PAHT-CF, PET-CF, PA6-CF, PLA-CF and PETG-CF, thus extending the lifespan of the extruder. It is also compatible with common filaments like PLA, PETG, ABS, ASA, PC and TPU.
This component is ideal for users who frequently print with abrasive materials containing carbon or glass fibres. In the event of wear (abrasion) or clogging due to long-term use, users can easily replace only this gear assembly, instead of the entire extruder unit. For P1 series printer owners, whose extruders are standardly equipped with stainless steel gears, this assembly offers an upgrade option to hardened steel for better wear resistance when printing technical filaments.
Key Features
- High Wear Resistance: Hardened steel ensures a longer lifespan when printing abrasive filaments.
- Reliable Filament Feeding: Precise gear interplay for consistent extrusion.
- Optimised for Technical Filaments: Ideal for materials with carbon or glass fibres (e.g., PAHT-CF, PET-CF).
- Easy Replacement: In case of wear, only the gear assembly can be replaced, not the entire extruder.
- Upgrade Option: Allows upgrading P1 series extruders from stainless steel to hardened steel.
Compatibility
- Bambu Lab X1 series
- Bambu Lab P1 series (including P1P)
