The Bambu Lab AMS is a useful accessory for multi-colour 3D printing. The automatic material system with a drying function includes 4 filament slots for different colours and can be installed in parallel with three other AMS systems to enjoy 16 different colours for printing.

To be able to use Bambu Lab AMS, a few things must be observed or certain requirements must be met:

► AMS only supports filaments with a diameter of 1.75 mm.

► AMS supports a wide range of filaments: PLA, PETG, ABS, ASA, PET, PA, PC, PP, POM, HIPS as well as Bambu Lab PLA-CF, PAHT-CF, PETG-CF.

► The following materials are NOT compatible with AMS: TPE, TPU, PVA, Bambu Lab PET-CF/TPU 95A and filaments from other brands that contain carbon or glass fibres.

After we have established which materials are compatible with AMS and which are not, we move on to the question of what requirements a filament spool must fulfil to be compatible with Bambu Lab AMS. There are two sizes:

► Spool width 50-68 mm

► Spool diameter 197-202 mm

In the table below you will find different brands and their filaments that are compatible with Bambu Lab AMS due to the spool dimensions.

*⇒ Attention: Plastic spools are recommended for use with AMS. Please note that cardboard spools can only be used to a limited extent or are not recommended for AMS. If necessary, you can print a suitable AMS spool adapter to be able to use cardboard spools. The spools marked with * require a special adapter ring. Here you can find a free STL file from Polymaker for printing a spool adapter.
