Bambu Lab AMS — Automatic Multi-Color & Multi-Material System The Bambu Lab AMS (Automatic Material System) enables automated multi-color and multi-material printing by managing up to four filament spools per unit. It handles filament switching, buffering, and monitoring automatically, allowing cleaner color transitions and more reliable long-duration prints. A sealed filament path, buffered feeding system, and built-in sensors help reduce tangles, manage humidity, and protect prints during material changes. The AMS is designed to integrate tightly with the Bambu Lab ecosystem for consistent, low-hassle operation. Key features • Supports up to 4 filament spools per AMS unit• Automatic filament switching during prints• Buffered feeding system for smooth, low-drag filament movement• Sealed filament path with desiccant storage to help manage moisture• Filament runout and tangle detection• RFID filament recognition on compatible spools• Expandable to support up to 16 materials or colors with additional AMS units Printer compatibility • P1 / P2 / X1 Series– Single AMS: requires a filament buffer– Multiple AMS units: requires a multi-port AMS hub • A1 / A1 Mini Series– Requires the A1 Series filament hub– AMS Lite cannot be mixed with standard AMS units on the same hub • Uses standard 1.75 mm filament• Moisture-sensitive filaments should be dried separately before loading Supported use cases • Multi-color aesthetic prints• Multi-material functional parts• Support material printing• Long-duration and unattended prints• Print farms and production environments What’s in the Box • Bambu Lab AMS unit (4-slot)• PTFE tubes (multiple lengths)• PTFE tube connectors• Bus cable – 6-pin• Bus cable – 4-pin• Filament buffer• Spare filament cutters ×2• Reusable filament spools ×3• High-temperature reusable filament spool• Desiccant packs (Additional hubs or adapters may be required depending on printer model and number of AMS units.) Important notes • AMS Lite is a separate system and is not interchangeable with standard AMS• Sealed design helps manage humidity but does not replace filament drying• Compatibility depends on printer model and configuration Policy snapshot AMS units, 3D printers, and filament are final sale. Approved returns on other items must be brand new and unopened; restocking fees and non-refundable shipping may apply.
