Bambu Lab 4-in-1 PTFE Adapter

Bambu Lab 4-in-1 PTFE Adapter

The Bambu 4-in-1 PTFE Adapter connects up to four filament input modules to a compatible printer at the same time. It supports configurations with one AMS plus up to three additional filaments—up to seven different filaments in total.

Compatibility

Use with AMS and specialty filaments

The adapter allows a printer to connect to an AMS alongside filaments not compatible with AMS, including TPU 95A, Bambu PET-CF, and other carbon-fibre or glass-fibre-containing filaments.

Installation and Direction

1. Connect the PTFE tube from the toolhead to the OUT end of the adapter.
2. When using AMS, connect the buffer output PTFE tube to an IN end; other compatible filaments use the remaining IN ends.
3. Without AMS, connect up to four filament wires to the IN ends.
4. Do not reverse IN and OUT: reversed connections may cause filament blockage.
