SUPER FILAMENT DRYER BOX WITH 4 SPOOLS The Sunlu S4 filament dryer box revolutionizes filament drying with its capacity to accommodate four 1kg spools at a time. With eight filament holes and PTFE tubing, this innovative dryer meets the need for drying multiple filaments and allows printing on four printers at the same time.
EFFICIENT HEATING & DRYING SUNLU S4 features PTC heating element and three-fan design that ensures even heat distribution in the dryer. The advanced system allows for fast heating up to 70°C, supported by a powerful 350W PTC heater that is 6.9 times more powerful than its predecessor, the SUNLU S2. This leads to accelerated and thorough filament drying.
Automatic Humidity Regulation: Equipped with a high-precision humidity sensor, the SUNLU FilaDryer S4 monitors indoor humidity in real time. When the humidity exceeds 50%, the dryer is automatically activated to prevent moisture, and at the same time serves as a storage box for 3D printer filaments.
User-friendly design: With an adjustable temperature range of 35°C to 70°C and a customizable drying time of up to 99 hours, the S4 delivers a seamless user experience through its intuitive touchscreen interface. Preset configurations for common filaments such as PLA, ABS, PETG, PA and PC simplify use and increase user comfort.
Versatile Compatibility SUNLU S4 filament dryer supports a range of high quality 3D filaments, including PLA, PLA+, PETG, TPU, ABS, PA, PC, Nylon and others. This dryer is compatible with standard filament diameters of 1.75mm, 2.85mm and 3.00mm and ensures wide usability for different filament types.
