In the world of 3D printing, using dry filament is crucial to achieving high-quality prints—especially in humid environments. The Sunlu AMS Heater offers an innovative solution for Bambu Lab AMS1 users by transforming the standard AMS unit into a dedicated filament dehydrator. This upgrade enables the simultaneous storage, drying, and printing of up to four spools, making it a real game-changer for anyone working with moisture-sensitive materials such as PLA, ABS, TPU, PA, and PC.
Key Features and Performance
The Sunlu AMS Heater Kit replaces the original AMS1 cover with a heating module that can warm the system to up to 70 °C in just 20 minutes—ideal for most 3D printing polymers. It features intelligent temperature control based on humidity levels, as well as triple overheating protection for added safety. Users can dry filaments independently of the printing process or even continuously while printing, a feature not available in the standard AMS. Preset modes for various materials simplify the process, and the noise level remains pleasantly low at 41–44 dB from a distance of one meter.
Pros and Cons
-
Pros: Rapid heating, intelligent humidity-based control, material-specific presets, and the ability to dry while printing.
-
Cons: No independent compartments for individual spools (only uniform heating), poorly visible display, less airtight cover without a locking mechanism, and a relatively high price (promotions can make it more affordable).
Overall, this accessory is particularly useful for AMS1 owners who use engineering polymers in humid conditions. However, a dedicated dehydrator remains non-essential for those who already own one.
