Dual-extrusion 3D printers significantly accelerate multi-color printing by reducing the flushing time required by single-extrusion machines. Traditionally, ensuring filaments reached the correct nozzle required manually swapping spools between AMS units. With the Filament Track Switch, those days are over. It intelligently routes any filament from your AMS units to whichever nozzle the slicer assigns, giving you total hardware flexibility and faster prints.

The filament track switch unbinds the AMS from specific nozzles, allowing any filament to feed into any nozzle regardless of configuration. This enables dynamic filament mapping, permitting mid-print color reassignments that significantly boost multi-color efficiency.

Please refer to the installation guide for the Filament Track Switch available on Bambu Lab Wiki. For a visual walkthrough, we also recommend watching the step-by-step installation video.
