SUNLU S2 FilaDryer

Many 3D printing filaments are hygroscopic, which means they readily absorb moisture from the environment when they are removed from the original package. Moisture can turn into steam in the hot end, leading to issues like poor layer adhesion, bubbling, or even clogging of the nozzle. Using a filament dryer box such as the SUNLU S2 is essential to ensure the quality, consistency, and reliability of your 3D prints.

Different 3D filaments absorb water at different rates, depending on their chemical composition. The S2 FilaDryer monitors in real-time the inside humidity and allows temperature level setting between 35℃ and 70℃. The dryer uses two heating elements that turn moisture into vapor, which is discharged through the filament outlet.

The SUNLU S2 Filament Dryer is compatible with 99% of FDM 3D printer materials regardless of brand, diameter ( 1.75mm/2.85mm/3.00mm), or type (PLA/PLA+, PETG, ABS, TPU, Nylon, and PA/PC).
