The AMS Hub is required when using multiple AMS units with a single printer. Single AMS setups connect directly without a hub. |
Bambu Lab AMS Hub – Multi-AMS Connection Hub
The Bambu Lab AMS Hub is the official multi-AMS routing component that connects up to 4 AMS units to a single printer. This hub manages filament routing, allowing the printer to select from up to 16 different filaments (4 per AMS) during multi-color prints.
Essential for multi-AMS setups or as a replacement when the original hub fails.
When to Replace
- AMS Communication Errors – One or more AMS units not detected or failing to respond to the printer
- Filament Routing Failures – Hub unable to select or route filament from the correct AMS slot
- Intermittent Connectivity – AMS units connecting and disconnecting randomly during prints
- Buffer Mechanism Stuck – Filament buffer inside the hub jammed, causing feeding resistance or tangling
- Physical Damage – Cracked housing, broken connectors, or damaged PTFE tube ports on the hub
Key Features
- 4 AMS Support – Connect up to 4 AMS units
- Filament Routing – Manages multi-source feeding
- Original Part – Genuine Bambu Lab quality
- Data + Filament – Handles both signal and filament
- Buffer System – Integrated filament buffer
- Plug-and-Play – Easy connection setup
How the AMS Hub Works
Hub Functions:
Each AMS connects to the hub with its own data cable and PTFE tube. The hub then connects to the printer with a single output. |
When You Need an AMS Hub
- Multiple AMS Units – Using 2, 3, or 4 AMS with one printer
- Hub Replacement – Original hub damaged or faulty
- Routing Issues – Problems with multi-AMS filament selection
- Communication Errors – AMS units not responding
- Expanding Setup – Adding more AMS units
