Bambu Lab Support published its X2D introduction to the Filament Track Switch on April 17, 2026. The dated video provides an official reference for how this accessory fits into a dual-nozzle workflow.[1]

The official store describes dynamic mapping of AMS filaments to nozzles. This changes the routing available to a print and reduces the need to regroup spools manually when different material combinations are required.[2]

The practical issue is material assignment: a multi-material job depends on where each filament is sent as well as how many materials are loaded. April 17 is the guide’s publication date. The available evidence does not establish it as the accessory’s first day on sale.[1][2]
