Product Features

- Air-tight Filament Storage
- Up to 24-color/Multi-material Printing
- Brushless Servo Feeding Motor

- AMS 2 Pro compatibility with A1/A1 mini printers will be added through an OTA update in Q3 2025.
- The AMS 2 Pro is compatible with X1/P1 series printers for multi-material printing.
- For X1/P1 owners, a switching adapter is needed to power the drying function. Since filament drying lasts long, you rarely need multiple adapters running simultaneously. The optional adapter helps lower the price.
- For H2D owners, your H2D can power anyone of the AMS 2 Pro(s) connected for drying, so if you're not planning to run multiple AMS 2 Pro for drying simultaneously, you won't be needing an adapter.
Dry Filament Quickly and Intelligently
Electro-Magnetic Air Vent
Automated venting facilitates dehumidification during drying and ensures airtight sealing for weeks of high-quality printing.
Auto-rotate Drying
During the drying process, the filament spools rotate automatically to ensure more even drying.

AMS 2 Pro uses RFID to auto-match drying settings for Bambu official filaments, no manual input needed.
Speed Up! Faster Multi-material Printing!
The powerful Bambu permanent magnet synchronous servo motor accelerates filament feeding by 60% for enhanced efficiency.
Saves an average of 10 minutes per 100 filament changes.

Tool-Free Filament Tubes Access
Removing snapped filament from the first-gen AMS requires extracting all spools and disassembling the shell with two screws, taking 3-5 minutes. In contrast, the AMS 2 Pro offers direct, tool-free access to filament tubes from the top.

Ceramic Inlet
Ceramic filament inlets with Vickers hardness of 1200 significantly enhances durability.
Compatible With All Bambu Lab Printers
The AMS 2 Pro will be compatible with all Bambu Lab products.
