This SUNLU AMS Heater is compatible with the Bambu Lab AMS - Automatic Material System.

Please note that this product is optimized and upgraded exclusively for Bambu Lab's AMS (1st gen),
and is not compatible with Automatic Material Systems from other Brands.
Regarding the visibility of the lid, the entire lid is not fully transparent. There is a transparent area on the front of the lid that allows you to see the internal operation.

Drying and printing are performed simultaneously. This is a heater that can upgrade the upper cover of the AMS. Compared to the traditional printing process using the AMS, which requires drying before printing, the upgraded version allows for simultaneous printing and drying.

Unique Air Duct Design. The innovative airflow system directs heat to circulate precisely around the filament area, ensuring efficient drying while protecting the AMS feeding motor from high temperatures. This design may also cause slight temperature and humidity differences between electronic components.

High-efficiency heating with uniform temperature distribution, reaching 70°C within 20 minutes. The dual airflow design ensures even heat circulation, preventing localized overheating of materials and effectively reducing the risk of thermal deformation.

High compatibility: After upgrading to the AMS Heater, it supports stacked 16-color printing and saves space. Upgrades the heater for the AMS Generation 1 upper cover, seamlessly integrating with the Generation 1 seal strip and fully compatible with the Generation 1 seal preservation function.

Simple upgrade process: Loosen—disassemble—tighten, completed in just 2 minutes.

Intelligent humidity monitoring:
① Humidity mode default heating temperature: 55°C—users can adjust and save the temperature.
② Default operating time: 6 hours.
③ After the countdown ends, the device does not shut down; it automatically starts heating when humidity rises to 50% and stops heating when humidity drops to 20%.
④ In rH mode, users can adjust humidity (range: 25%–50%).
After adjustment, the humidity automatically starts using this set value.

Safe and Reliable:
PTC heating. Dual-level protection with a temperature control switch. Software-based intelligent temperature control, real-time temperature monitoring, and automatic control of the heating system. Maximum drying temperature of 70°C. Alarms are triggered when the temperature exceeds the set value by 10°C, when the temperature fails to rise, or when the fan malfunctions. The device operates according to the set time and automatically shuts down when the time reaches zero.
