Bambu Lab AMS 2 Pro - Automatic Material System

Elevate your 3D printing capabilities with the AMS 2 Pro—the next evolution of Bambu Lab’s material handling. This smart accessory enables seamless multi-material and multi-color prints while keeping your filament dry and pristine.

Key Features

• Active Air Vent & Filament Drying (up to 65 °C) – Utilizes an electromagnetic vent and automatic spool rotation to dehumidify materials quickly and store them air-tight for lasting print quality. 
• Up to 24 Filament Capacity – Stack up to 4 AMS 2 Pro units or mix with AMS HT units to handle as many as 24 different filaments for expanded creative flexibility. 
• Brushless Servo Feeding Motor – Speeds filament switching by up to 60% faster, saving roughly 10 minutes per 100 changes. 
• RFID Filament Sync – Automatically recognizes and applies optimal drying settings for Bambu official filaments—no settings to fiddle with. 
• Tool-Free Access & Durability – Top-access filament tube slots mean faster and easier maintenance. Ceramic-reinforced inlets enhance wear resistance. 

Compatibility & Connectivity

• Supports current X1 and P1 series printers for both multi-material printing and drying. 
• A1 / A1 mini printers will gain compatibility through an OTA software update by Q3 2025. 
• Drying function: May require an optional external power adapter depending on printer model and number of connected AMS 2 Pro units—especially for X1/P1 series. H2D printers can often power one unit directly. 

What’s in the Box

• AMS 2 Pro unit
• Desiccant pack
• PTFE tubes (185 mm × 2, 225 mm × 2, and 900 mm × 1)
• 6-pin Bambu bus cable
• (Optional add-ons such as buffers, hubs, tubing, and adapters available per printer configuration.) 

Why You’ll Love It

• Dramatically improves filament quality, delivering consistently reliable prints—especially in humid environments.
• Expands creative freedom with up to 24 materials/colors on tap.
• Simplifies workflow with auto-drying, RFID, and rapid feeding—all designed to work out of the box or with minimal setup.

Pro Tips

• If you’re a P1 or X1 user intending to use the drying feature, make sure to get the upgrade kit with the filament buffer or AMS hub—and the external switching adapter as needed.
