The Bambu Lab AMS Internal Hub Unit is the OEM replacement component for the central hub assembly inside the Automatic Material System. The internal hub coordinates filament routing between the four AMS slots and the output channel, playing a central role in smooth, error-free multi-material switching during automated print runs.

When the AMS internal hub shows signs of wear, mechanical damage, or causes recurring filament routing errors, replacing this unit restores full AMS functionality. This is an official Bambu Lab spare part designed for direct compatibility with the AMS unit used on X1C, X1E, and P1S printers.
