Question 1

Is the SUNLU AMS Heater compatible with the Bambu Lab AMS Gen 2, or only Gen 1?**

Accepted Answer

This heater is specifically designed for the **Bambu Lab AMS Gen 1**. While some users have attempted modifications, it is not officially compatible with the AMS Gen 2 due to differences in the base design and electronics. For Gen 2 users, we recommend checking SUNLU or Bambu Lab for a dedicated solution.

Question 2

How difficult is the installation, and do I need to modify my AMS?**

Accepted Answer

Installation is straightforward and requires **no permanent modification** to your AMS or printer. You simply place the heater unit underneath your AMS, connect the two flexible ducts to the ports on the AMS base, and plug it in. The most common tip from users is to ensure the ducts are seated firmly to prevent air leaks.

Question 3

Can this dryer fully dry a completely wet spool of filament, and is the "20-minute" claim accurate?**

Accepted Answer

Think of the AMS Heater as a brilliant **maintenance dryer** rather than a heavy-duty recovery dryer. It heats up to 70°C very quickly (in about 20 minutes) and is extremely effective at *keeping dry filament dry* and *removing residual moisture* during printing. For a severely waterlogged spool, most users (and social media reviews) recommend first using a dedicated sealed dryer for several hours, then using the AMS Heater to maintain that dryness during the print.

Question 4

Is it safe to run this heater continuously during long, multi-day prints?**

Accepted Answer

Yes. The product is designed for continuous operation and features triple protection (overheating, over-current, and fan failure protection) for safety. Many enthusiastic users on forums like Reddit report running it for 24+ hour prints without issue, noting it provides consistent performance and peace of mind with problematic filaments like PETG or Nylon.

Question 5

Who would benefit most from this product, and who might want to consider an alternative?**

Accepted Answer

You'll benefit most if you own an AMS Gen 1, print with moisture-sensitive materials, and value a streamlined, "set-and-forget" workflow. It's a game-changer for preventing mid-print issues. If you primarily print with simple PLA in a dry climate, or if you already own and prefer using a high-end standalone dryer for all your filament, this product may be less essential for your setup.
