Why is Desiccant Still Needed in the AMS HT? 

Desiccant is used in an active filament dryer to absorb moisture from the air surrounding the filament. Here's why this is necessary:

1. Filament is hygroscopic: Most 3D printing filaments (like PLA, ABS, PETG, and especially nylon) absorb moisture from the air. Even small amounts of water can lead to:
   • Poor print quality (stringing, bubbling, inconsistent extrusion)
   • Weakened mechanical properties
   • Clogged nozzles
2. Active drying still requires moisture removal: An active filament dryer typically heats the filament to release absorbed moisture, and the desiccant:
   • Traps that moisture, preventing it from re-entering the air inside the dryer
   • Speeds up drying by maintaining a low-humidity environment
3. Maintains dry storage conditions: Even after drying, the desiccant helps keep the air inside the dryer dry, preserving filament quality until it's used.

Important Features:

• Top loading of desiccant is key!
  • Front loading holders seems risky, if they open and leaks beads in the AMS HT,  it could cause some real damage to fans and heater.

Printing Notes:

• If you plan on using the drying feature of the new AMS HT, Print this box in PETG or ABS.
• Be sure to clean your build plate.
• FYI:  If your printer keeps pausing due to AI detection issue, It's not learning…  TURN OFF AI Detection.

Installation Notes:

• Fill the desiccant box with your choice of desiccant beads or just fill with desiccant packets.
  • Use the orange rechargeable desiccant (The blue is known to be toxic)
  • I found this desiccant works great and can be recharged in 6 minutes in your microwave.
• Slide the lid onto the box (It's a nice tight lid).
• Remove the rear roller from the AMS HT (Just pop it up)
• Place box into the rear of your AMS HT with the Bambu logo facing forward (either way will work)
