Bambu Lab AMS 2 Pro

The Bambu Lab AMS 2 Pro is the second-generation Automatic Material System: a sealed box that holds four 1.75 mm spools, feeds them to the printer automatically and dries them while they wait. One AMS 2 Pro gives four colours or materials in a print; Bambu Lab printers can chain several units for more. Filament is not included — the spools in the photos are for illustration only.

Active drying up to 65 °C

Two drying modules (heater, fan and temperature sensor) heat the box up to 65 °C (reached when the room is above 25 °C) while the spools rotate. Electro-magnetic air vents open to push moist air out and close to keep the box airtight, with a gasket and colour-changing desiccant for storage. Humidity and temperature show on the printer screen, Bambu Studio and Bambu Handy. Drying needs the AMS connected to a powered-on printer. Bambu Lab notes that ABS, ASA, PA, PC, PET, PVA, BVOH and CF grades cannot be fully dried at 65 °C and recommends the AMS HT for those.

Faster, smarter feeding

A brushless servo assist motor feeds about 60 % faster than before, ceramic inlets resist wear, and dual-coil RFID reads Bambu Lab filament to set the material, estimate what is left, refill automatically from a matching spool and choose drying settings. Filament tubes are reachable from the top without tools.

Compatibility and what you may also need

Bambu Lab lists the AMS 2 Pro as compatible with its printers, but the extra parts depend on the printer:

• H2D / H2C / H2S, X2D, P2S: buffer built in or included with the printer (the standalone P2S needs the P2S Filament Buffer). Larger setups need a 4-in-1 PTFE adapter (H2-series version for the H2C). The printer can power drying for one unit; each extra unit drying at the same time needs an AMS 2 Pro Switching Adapter.

• X1 / P1 series: one unit needs a Filament Buffer, PTFE tube coupler and 4-pin cable; two or more need an AMS Hub (combo printers already have the buffer). Every unit that dries needs its own Switching Adapter.

• A1 series: needs the AMS Hub – A1 Series and printer firmware 01.07.00.00 or later; each drying unit needs a Switching Adapter.

• A2L and H3C: see Bambu Lab's compatibility guide; the H3C needs the H3C Buffer.

What is in the box

According to Bambu Lab: AMS 2 Pro, desiccant, PTFE tubes (2 × 185 mm, 2 × 225 mm, 1 × 900 mm) and a 6-pin Bambu Bus cable. No filament, power adapter, buffer or hub is included.

Global Version or Chinese Version?

Bambu Lab publishes a single AMS 2 Pro specification and we found no official hardware difference or region lock for the AMS itself. The two options show the supply channel: Global Version from Bambu Lab's international channel, Chinese Version from the mainland-China channel. Bambu Lab states that it does not support cross-regional service, so warranty service follows the region of purchase. Ask us which version is available before ordering.
