Automatic material handling with drying and multi-material support

The Bambu Lab AMS 2 Pro is an automatic material system that expands compatible Bambu Lab 3D printers for multi-material printing, filament drying, and sealed filament storage. It is built to support larger colour or material setups while improving feeding speed and day-to-day filament management.

The system supports serial connection of up to 4 AMS 2 Pro units and 8 AMS HT units, for a total of 24 filaments. That configuration is suited to complex multi-colour jobs, material switching workflows, and print environments where keeping multiple spools ready matters.

Filament drying with automated moisture control

The AMS 2 Pro is designed to dry filament quickly and manage humidity with less manual intervention. The drying system combines vent control, spool rotation, and automatic settings for supported filaments to simplify preparation before printing.

Electro-magnetic air vent for drying and sealed storage

Automated venting helps dehumidify the chamber during drying, then closes to maintain an airtight seal for weeks of high-quality printing. This design supports both active drying and longer-term filament protection between print sessions.

Auto-rotate drying for more even results

During the drying process, the filament spools rotate automatically. That movement helps promote more even drying across the spool instead of concentrating heat and airflow in one position.

RFID sync for Bambu official filaments

The AMS 2 Pro uses RFID to auto-match drying settings for Bambu official filaments. Manual input is not required when a supported Bambu filament is recognised.

Faster filament changes for multi-colour printing

The Bambu Lab AMS 2 Pro is built to reduce the time overhead that comes with multi-material printing. A permanent magnet synchronous servo motor increases filament feeding speed by 60%, which helps shorten pauses during swaps and improves overall workflow efficiency.

Bambu Lab states the AMS 2 Pro saves an average of 10 minutes per 100 filament changes. For users running frequent colour transitions, that reduction can add up across longer or more complex prints.

Design improvements for maintenance and durability

The AMS 2 Pro includes updated design details that make routine use easier and improve wear resistance in high-use printing setups. These changes focus on filament access and longer-lasting contact points.

Tool-free filament tube access

Accessing snapped filament is faster on the AMS 2 Pro than on the first-generation AMS. Removing broken filament from the original AMS requires taking out all spools and disassembling the shell with two screws, a process that takes about 3 to 5 minutes, while the AMS 2 Pro provides direct tool-free access to the filament tubes from the top.

Ceramic filament inlet for higher wear resistance

The ceramic filament inlets are designed for improved durability. With a Vickers hardness of 1200, the inlet material significantly enhances wear resistance in an area that sees repeated filament movement.

Where the AMS 2 Pro fits best

• Multi-colour 3D printing: Supports larger filament banks for projects that require frequent colour changes.
• Moisture-sensitive filament handling: Drying up to 65°C and airtight storage help prepare and preserve filament between prints.
• Higher-throughput print workflows: Faster feeding and reduced changeover time help when running many swaps in a single job.
• Frequent maintenance environments: Tool-free access to filament tubes makes clearing snapped filament quicker.
• Long-term durability needs: Ceramic inlets with high hardness are suited to repeated filament loading and unloading.
