Product description: Sunlu AMS Heater - heating module for Bambu Lab AMS Gen 1
The Sunlu AMS Heater is a heating module for the Bambu Lab AMS Gen 1 that allows for simultaneous filament drying and 3D printing . It replaces the standard AMS cover, offering temperature and humidity control without the need for a separate dryer. By heating up to 70°C in approximately 20 minutes , it effectively reduces humidity , improving print quality and extrusion stability. The model is equipped with intelligent humidity monitoring and dual airflow for even heat distribution. It supports multi-color printing with up to 16 colors, and assembly takes approximately 2 minutes and requires no printer modifications.

Sunlu AMS Heater is a heating module for Bambu Lab AMS Gen 1 that allows you to dry filaments and 3D print simultaneously.
Special features
- Drying and printing simultaneously: the filament is dried while the printer is running, without the need for prior material preparation
- Fast heating: reaches 70°C in about 20 minutes
- Intelligent humidity control: automatic start of heating when the set humidity level is exceeded
- Humidity regulation RH: possibility to set the activation threshold from 25% to 50% RH
- Dual airflow: even heat distribution without local overheating of filaments
- AMS Gen 1 Compatibility: Full integration with the first generation Bambu Lab AMS system
- Multi-color printing support: ability to work in configurations of up to 16 colors
- Safe design: PTC heater, double thermal protection and intelligent temperature control
- Real-time temperature monitoring: automatic control of fan and heating system operation
- Easy installation: loosen-remove-tighten installation in about 2 minutes
- Touch control panel: quick configuration of temperature, time and operating modes
- Space-saving: heating function integrated directly into the AMS cover
Practical applications
The AMS Heater is ideal for printing with materials requiring low humidity, especially in environments with high humidity. It enables stable multi-color printing without compromising the quality of filaments stored in the AMS. The device is an ideal solution for Bambu Lab printer users using technical filaments such as PET-CF, PA-CF, TPU, or ABS. It helps reduce moisture-related issues and improves surface quality, mechanical strength, and print stability.
