Filament Dryer



Note: SUNLU FilaDryer S1 Plus is the new version of the original SUNLU FilaDryer S1 with enhanced features:

  • Built-in fan further ensures even heating temperature
  • Real-time display of humidity

Given Singapore's high humidity weather, 3D printing filaments generally do not last very long and get too moist and brittle over time. PLA and ABS are especially vulnerable to this issue as they are hygroscopic, meaning they readily try to absorb moisture from the air. This product from Sunlu combats this problem very well by keeping your filament in a dry box while you print! The upgraded FilaDryer S1 Plus works with various filament diameters and dries your filament quickly and evenly. See below for more details!
