Bambu Lab AMS 2 Pro Switching Adapter

Unlock the full drying capability of your AMS 2 Pro with the official Bambu Lab AMS 2 Pro Switching Adapter. This adapter delivers the consistent power required to properly dry filament—especially when running multiple AMS 2 Pro units.

If you plan to dry filament in more than one AMS 2 Pro at the same time, each unit must be powered by its own Switching Adapter to ensure optimal performance and consistent results.

Why Drying Matters

Moisture is one of the most common causes of poor 3D printing results. Many filaments are hygroscopic, meaning they absorb moisture from the air—even straight out of the package.

WHAT HAPPENS IF YOU DON’T DRY?

⚠️ Print Quality Issues

• Stringing & oozing
• Poor layer adhesion
• Rough or inconsistent surface finish
• Blobs, zits, and gaps

🔊 Audible & Visible Problems

• Popping or crackling during printing
• Steam bubbles forming in the nozzle

📉 Performance Loss

• Weak, brittle prints
• Reduced strength and durability
• Even “new” filament can arrive with moisture

WHY DRYING MATTERS

✅ Better Prints

• Smoother surfaces
• Cleaner details
• Stronger layer bonding

✅ Consistency

• Reliable extrusion
• Fewer failed prints

✅ Material Protection

• Extends filament lifespan
• Prevents waste and reprints

Which Filaments Need Drying?

🔴 Highly Hygroscopic (Always Dry)

• Nylon (PA)
• Polycarbonate (PC)
• TPU / Flexible filaments
• PVA (support material)

🟠 Moderately Hygroscopic (Dry Recommended)

• PETG
• ABS
• ASA

🟢 Low Moisture Sensitivity (Dry If Needed)

• PLA
• PLA+

Key Features

• Enables Filament Drying: Supplies required power for AMS 2 Pro drying function
• Multi-Unit Ready: Required when drying with multiple AMS 2 Pro units
• Prevents Power Drop: Maintains stable drying temperatures and performance
• Official Bambu Lab Accessory: Designed for safe, seamless compatibility

Printer Compatibility & Usage

H2 Series, X2D, & P2S Printers

• Single AMS 2 Pro:
  • Powered directly by the printer
  • No Switching Adapter required
• Multiple AMS 2 Pro Units:
  • Each unit requires its own Switching Adapter when drying
  • Recommended even if only one unit is drying to avoid power reduction

X1 & P1 Series Printers

• Drying Function:
  • Switching Adapter is required for proper drying
• Multiple AMS 2 Pro Units:
  • Each unit requires its own Switching Adapter when drying
• Without Drying Function:
  • Adapter not required for standard multi-material use

Important Notes

• AMS 2 Pro supports multi-material printing on X1/P1 series without the adapter when not drying
• For best drying results, always use a Switching Adapter
• AMS HT does NOT require a Switching Adapter — it includes its own dedicated power cord

What’s Included

• 1 × AMS 2 Pro Switching Adapter

Compatibility

• Bambu Lab AMS 2 Pro

Ensure your filament stays dry, your prints stay strong, and your workflow stays consistent with the power solution designed specifically for AMS 2 Pro drying.
