Product Description
Bambu Lab Filament Track Switch is an original Bambu Lab module designed as a smart filament flow switch between the
AMS system and the hotends of dual printers, primarily the
Bambu Lab X2D. It allows for the release of fixed assignment of AMS units to specific nozzles and ensures that
any filament from the AMS can be redirected to the left or right nozzle as needed by the slicer.
This gives you
dynamic filament mapping – Bambu Studio can change which AMS slot supplies which nozzle during printing, thereby:
- significantly reducing the purge tower and waste
- speeding up color and material changes
- making better use of the capacity of multiple AMS units
Currently, the Filament Track Switch is supported for
Bambu Lab X2D; support for H2C and H2D is planned in future firmware and Bambu Studio updates.
Main Advantages
- Dynamic Filament Routing
Releases the AMS from fixed assignment to one nozzle. Any AMS slot can supply both the left and right nozzle according to the settings in the slicer.
- Higher Efficiency of Multi-Color Printing
Less need for purge, less waste, and shorter color change times thanks to smarter filament paths.
- Better Utilization of Multiple AMS Units
On dual printers with multiple AMS units, it is possible to optimize which AMS and which slot supplies a specific nozzle at any time – ideal for extensive CMYK, gradient, or multi-material projects.
- Full Integration with Bambu Studio
The Filament Track Switch function is supported in newer versions of Bambu Studio (e.g., 2.5.x), where the module's behavior can be fully configured.
- Original Bambu Lab Accessory
Guaranteed compatibility, high-quality processing, and seamless integration with the Bambu ecosystem (AMS 2 Pro, AMS HT, etc.).
Compatibility
- Currently Supported:
- Bambu Lab X2D (dual FDM printer)
- Planned / Expected Support (after updates):
- Bambu Lab H2C
- Bambu Lab H2D
The maximum number of AMS units that can be connected is limited by the capabilities of the specific printer (e.g., X2D supports multiple AMS in various configurations). The Filament Track Switch acts as an
intelligent hub, so it does not limit the number of AMS units, but rather the way their outputs are routed to the hotends.
Note: Filament is always guided alternately, not simultaneously into both nozzles – when switching, the AMS first retracts the filament and then feeds it into the second path.

Installation and Use
- Perform installation according to the official Bambu Lab instructions (Wiki / video tutorial).
- The module is usually mounted on the back of the printer near the filament inlets.
- Connection:
- connect the PTFE tubes between the AMS, Filament Track Switch, and filament inlets on the printer,
- connect the 6-pin cable to the dedicated port on the printer,
- in Bambu Studio, activate Filament Track Switch support and configure which inlets/AMS supply individual nozzles.
After correct installation, specific AMS slots can be assigned to the left or right nozzle in Bambu Studio according to the model, colors, or material. The slicer then automatically optimizes switching to minimize purge and delay times.
Who is the Filament Track Switch suitable for
- Users of Bambu Lab X2D who want to maximize the potential of dual nozzles and multiple AMS units.
- Creators of multi-color models, product prototypes, and commissions where speed and efficiency matter.
- Advanced users working with a large number of colors or materials who want to reduce unnecessary waste and time required for filament changes.
Summary
Bambu Lab
Filament Track Switch is a key upgrade for dual Bambu printers (especially X2D), which
unlocks the full potential of multi-color and multi-material printing. It allows for smart redirection of filament from the AMS into any nozzle,
reduces purge waste, speeds up printing, and brings a professional workflow to everyday 3D printing.
Key Features:
- Dynamic filament mapping from AMS to both left and right nozzles on Bambu Lab X2D
- Significant reduction in purge waste and faster multi-color printing
- Smart filament flow hub controlled by Bambu Studio
- Compatible with multiple AMS units within printer limits
- Full integration into the Bambu Lab ecosystem (X2D, future H2C/H2D support)
- Simple assembly with provided 6-pin cable, PTFE tubes, and screws
