SUNLU AMS Heater is an intelligent filament dryer for the Bambu Lab AMS (1st generation) that enables filament drying during printing for more stable results and higher print quality. It offers fast heating up to 70 °C, even air circulation, and automatic humidity monitoring, so the filament stays in optimal condition without unnecessary downtime.
Moist filament often causes stringing, bubbles, brittle layers, or inconsistent material flow. SUNLU AMS Heater is designed as an add-on for the top cover of the Bambu Lab AMS (1st generation) and solves the problem at the source — it continuously dries the filament during printing, so you don’t have to wait for pre-drying.
Thanks to PTC heating, the device reaches up to 70 °C in about 20 minutes. Thoughtful air channels guide heat around the spools and ensure even drying without the risk of overheating sensitive AMS parts (e.g., the feeder motor).
Main advantages:
- Drying during printing — stable conditions throughout the entire print process
- Fast heating 35–70 °C — higher work efficiency
- Intelligent rH mode — automatic real-time humidity monitoring and regulation
- Adjustable humidity threshold in the range of 25–50% for different materials
- Easy installation without special tools (about 2 minutes)
- Compact solution suitable even for multi-color setups up to 16 colors without increasing space requirements
