The Bambu Lab AMS Active Extrusion Wheel Assembly is the motorised drive wheel module responsible for pushing filament through the AMS (Automatic Material System) feed path and into the printer's PTFE tube. This is the active, driven component in the AMS extrusion mechanism, working against the passive side to grip and advance the filament with precise, controlled force. It is the OEM replacement part for worn or damaged extrusion wheels that cause slipping, under-extrusion or filament feeding failures.

The extrusion wheel is a high-wear component in any intensively used AMS setup, particularly when printing with abrasive or textured filaments. Replacing it with a genuine Bambu Lab OEM assembly restores the original drive force, grip quality and dimensional accuracy needed for consistent, reliable multi-colour printing over long runs.

Key features

• OEM Bambu Lab motorised (active) drive wheel module for the AMS extrusion mechanism.
• Restores correct filament grip and feed force to prevent slipping and under-extrusion in worn AMS units.
• Designed for high-cycle use with all Bambu Lab filament types, including abrasive materials.
• Direct OEM replacement - exact fit and compatibility with Bambu Lab AMS on X1, P1 and A1 series.
• Resolves feeding failures and inconsistent extrusion caused by worn wheel surfaces or drive components.

Compatible with: Bambu Lab AMS (X1 series, P1 series, A1 series)
