Bambu Lab AMS lite Filament Hub is a key component for multi-color or multi-material 3D printing, serving as the connector between up to four PTFE tubes from the AMS lite and the extruder of the printer. It enables reliable, automatic filament switching by guiding filaments from different spools to the extruder and incorporates a tangle detection module for secure and uninterrupted material feed. The hub is made of plastic and metal, features a compact design (60 × 60 × 30 mm, 30 g), and includes buckles for secure mounting.
