Bambu Lab AMS - Automatic Material System

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
