BambuLab AMS 2 Pro Automatic Material System for Bambu Lab 3D Printers, 4-Spool Multi-Color Printing, RFID Filament Detection, Humidity Control, Black

Running out of filament mid-print or manually swapping spools for multi-color projects interrupts your workflow and wastes time. The BambuLab AMS 2 Pro solves this by automatically managing up to four filament spools, enabling seamless multi-color printing and uninterrupted long prints. It keeps filament dry, detects tangles, and loads/unloads material without your intervention, so your printer keeps producing while you focus on design.

Who is it for

This system is ideal for Bambu Lab X1 Series, P1P, P1S, and A1 Series printer owners who want reliable multi-color printing, automated filament handling, and protection against moisture-related print failures. Whether you run a print farm, a design studio, or a home workshop, the AMS 2 Pro reduces downtime and expands creative possibilities.

Tips

To maximize performance, place the AMS 2 Pro on a stable surface near your printer and ensure the desiccant is replaced regularly to maintain low humidity. For multi-color prints beyond four colors, connect multiple AMS units via the AMS Hub (sold separately). Always use Bambu Lab RFID spools for automatic material recognition, or manually configure settings for third-party filaments.
