Bambu Lab AMS 2 Pro Automatic Material System

The Bambu Lab AMS 2 Pro Automatic Material System is designed to make multi-color, multi-material, and filament management workflows easier for compatible Bambu Lab 3D printers. It allows users to load multiple filament spools and automatically switch between them during printing, reducing manual filament changes and improving workflow efficiency.

Compared with a basic spool holder, the AMS 2 Pro adds smart filament handling, RFID filament sync, airtight storage, active moisture discharge, and filament drying up to 65°C. This makes it useful not only for colorful prints, but also for keeping filament in better condition before use.

The AMS 2 Pro is suitable for makers, schools, studios, print farms, and professional users who regularly print with multiple colors or materials and want a cleaner, more automated printing setup.

Key Features

• Automatic material system for compatible Bambu Lab printers

• Supports multi-color and multi-material printing

• Up to 65°C active filament drying

• Airtight filament storage with active moisture discharge

• RFID filament sync for Bambu official filaments

• Brushless servo feeding motor for faster filament feeding

• Supports 1.75mm filament

• Expandable up to 24 filaments with compatible AMS 2 Pro and AMS HT setup

Multi-Color and Multi-Material Printing

The AMS 2 Pro allows compatible Bambu Lab printers to automatically switch between different filament spools. This is useful for colorful models, logos, text, signs, display parts, educational prints, and functional parts that need different material types.

It helps reduce manual filament changes and makes multi-color printing more practical for everyday use.

Active Filament Drying up to 65°C

The AMS 2 Pro includes active filament drying with a maximum drying temperature of 65°C. This helps reduce moisture in compatible filaments before printing, which can improve print quality, surface finish, extrusion consistency, and layer bonding.

Moist filament can cause stringing, bubbles, weak layers, rough surfaces, and inconsistent extrusion, so integrated drying is especially useful for users printing regularly in humid environments.

Airtight Filament Storage

The AMS 2 Pro is designed with airtight filament storage and active moisture discharge. Its electro-magnetic air vent supports drying and then helps maintain a sealed storage environment after drying.

This makes it useful for keeping filament loaded and ready for printing while reducing exposure to ambient humidity.

RFID Filament Sync

When used with Bambu official RFID-enabled filaments, the AMS 2 Pro can automatically identify filament information and match drying settings. This helps reduce manual setup and makes filament management easier for users who print with multiple colors and material types.

RFID support can also improve workflow convenience inside Bambu Studio and Bambu Handy.

Faster Feeding with Brushless Servo Motor

The brushless servo feeding motor improves filament feeding speed and efficiency. This helps reduce time during repeated filament changes, especially in multi-color prints where many material switches may happen in one job.

For large multi-color models, faster feeding can help reduce total printing time and improve workflow efficiency.

Improved Maintenance Design

The AMS 2 Pro includes tool-free access to filament tubes from the top, making it easier to clear snapped filament or check the filament path compared with more enclosed systems.

It also uses ceramic filament inlets for better durability during repeated filament feeding.

Expandable Filament System

One AMS 2 Pro can manage multiple loaded spools, and compatible Bambu Lab setups can be expanded with additional AMS 2 Pro and AMS HT units for up to 24 filaments. This is useful for advanced multi-color printing, material libraries, print farms, and users who want more ready-to-print filament options.

Actual expansion support depends on the printer model, firmware, accessories, and connection setup.
