The Filament Track Switch is an accessory for Bambu Lab dual-nozzle printing that routes filament from AMS units to the nozzle assigned by the slicer. It is designed to eliminate manual filament re-grouping and support dynamic filament mapping for multi-colour printing.

Key features and benefits

• Eliminates manual filament re-grouping: The switch intelligently routes filament from AMS units to the nozzle selected by the slicer.
• Dynamic mapping for efficiency: Any filament can feed into any nozzle, which supports mid-print colour reassignments and more flexible print setup.
• Supports dual-nozzle use: On compatible dual-nozzle printers, a single AMS can support filament switching between the left and right hotends when used with the switch.
• Installation resources available: The product page references a Bambu Lab Wiki installation guide and a step-by-step installation video.

Use cases

• Multi-colour 3D printing on supported Bambu Lab printers.
• Reducing manual spool swapping between AMS units during dual-nozzle printing workflows.
• Managing filament routing for prints that need flexible nozzle assignment.
• Using AMS-based filament switching on X2D, H2D, and H2C printers.
