@sunlu_official: Your filament stays protected even after the drying cycle ends.🔒 With rH Mode, the SUNLU AMS Lite Heater continuously monitors chamber humidity after drying and automatically manages heating when needed. 💧 Smart Humidity Control – when chamber humidity reaches your preset threshold (adjustable from 25%–50%), heating automatically restarts. When humidity drops to 20% RH, heating stops and returns to monitoring mode. 🛡 Multiple Safety Protection – built with Temperature Monitoring, PTC Thermal Cut-Off Protection, and Smart Software Safety Control to ensure reliable operation. Keep your filament protected, monitored, and ready for your next print. 🔗 Learn more about AMS Lite Heater: https://bit.ly/4vStmD4 #sunlu #3dprinting #3dprinter #official #bambulab #newproduct
