Make Multi-Color 3D Printing Real! Color, the ultimate expression of emotions, is brought to you by Bambu Lab's Automatic Material System (AMS). You can now enjoy printing freely in multiple colors and materials. Product Features: Active Air Vent 65°C Filament Drying Air-tight Filament Storage Up to 24-color/Multi-material Printing Brushless Servo Feeding Motor RFID Filament Sync 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. 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. Compatible with Bambu X1E, X1C, P1S, P1C, H2D 24 Colors/Multi-Material: Serially connect up to 4 AMS 2 Pro & 8 AMS HT units, total of 24 filaments Electro-Magnetic Air Vent : Fast filament drying & air-tight filament storage. Automated venting facilitates dehumidification during drying and ensures airtight sealing for weeks of high-quality printing. 65° Celsius Drying: Up to 65°C drying temperature Brushless Motor: 60% faster feeding speed Auto Rotate Drying: During the drying process, the filament spools rotate automatically to ensure more even drying. Automatic Filament Identification: Bambu Lab filaments use RFID which is read by the AMS to automatically identify and apply the best settings for your material. RFID Sync: AMS 2 Pro uses RFID to auto-match drying settings for Bambu official filaments, no manual input needed. Tool Free Filament 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.
