AMS 2 Pro Upgrade Kits
A versatile system for your Bambu Lab multi-material 3D printers, designed to boost functionality
Two kits are available to ensure smooth operation and enhanced features:
- Kit 1 with Filament Buffer: Ideal for one AMS 2 Pro on X1 or P1 printers, including a Filament Buffer, 4-pin cable, Switching Adapter for drying, and PTFE tubes with couplers.

- Kit 2 with AMS Hub: Perfect for multiple AMS 2 Pro units, featuring an AMS Hub instead of a Buffer, with the same cables and accessories.

Upgrade Kit | Contents | Purpose |
AMS 2 Pro Upgrade Kit 1 with Filament Buffer | Filament Buffer, 4Pin Cable, Switching Adapter 1, PTFE Couplers, PTFE Tubes (370mm, 550mm) | Single AMS 2 Pro connection for X1/P1 |
AMS 2 Pro Upgrade Kit 2 with AMS Hub | AMS Hub, 4Pin Cable , Switching Adapter PTFE Couplers, PTFE Tubes (370mm, 550mm) | Multiple AMS 2 Pro connections for X1/P1 |
These upgrade kits are game-changers for 3D printing enthusiasts.
They enable:
Seamless Multi-Material Printing: Switch filaments effortlessly for intricate, multi-color designs. | | Filament Drying: Keep materials dry for consistent print quality, especially for hygroscopic filaments. |
 | |  |
Scalability: Expand your setup with multiple AMS units for increased filament capacity.
For H2D printer users, connecting multiple AMS 2 Pro units is simpler, with direct 6-pin cable compatibility and no need for additional adapters for drying.
Compatibility and Updates
- These kits work with X1 and P1 series now, with drying enabled by an OTA update by April 2025's end.
