Automatic multi-material handling and drying
Bambu Lab AMS 2 Pro 3D printing service
The Bambu Lab AMS 2 Pro is a four-spool automatic material system. It handles colour or compatible-material changes, keeps loaded filament sealed and adds active drying up to 65°C. For a print service, its most useful roles are automatic refill on long jobs, controlled storage and deliberate two-material work such as support interfaces or permanent markings.

What we use it for
- Automatic refill from a matching spool during long prints
- Permanent two-colour legends, markers and identifiers
- Support-interface material on compatible geometries
- Keeping common materials sealed and ready between jobs

Use the service instead of buying?
Ownership makes sense for frequent hands-on iteration. For occasional work, a service avoids setup, maintenance, material inventory and the cost of failed learning prints.
- The colour and material change strategy is planned before the print, including purge waste.
- Filament handling and drying are part of production rather than equipment you need to manage.
- Automatic refill reduces the risk of a long print stopping at the end of a spool.
- A single multi-colour part can be ordered without owning several full spools yourself.
Limits behind the specification
- Every colour or material change adds time and purge waste, sometimes substantially.
- Not every flexible or fibre-filled filament is suitable for feeding through an AMS.
- A 65°C dryer cannot fully dry every engineering polymer; some grades need higher-temperature drying.
- Multi-material printing only works when the materials adhere and behave compatibly in the same part.

Frequently asked questions
Can the AMS 2 Pro print four colours?+
It can feed four loaded spools to a compatible printer, but each change adds time and purge waste. A coloured surface detail may be sensible; hundreds of changes through every layer may not be.
Does the AMS 2 Pro dry nylon?+
It reaches 65°C and supports drying for several materials, but Bambu Lab notes that some engineering filaments need more heat than the unit can provide for complete drying.
Can TPU be used in the AMS 2 Pro?+
Only AMS-compatible grades should be assumed suitable. Generic soft TPU and several fibre-filled materials are specifically excluded by the manufacturer, so the exact filament must be checked.
