SUNLU FilaDryer S2 - 3D Printer Filament Dryer

The SUNLU FilaDryer S2 Filament Dryer is a conditioning unit for FDM 3D printing. It removes moisture from filament spools before and during printing, reducing problems such as nozzle clogging, poor layer adhesion, and uneven extrusion. The device supports standard filament diameters of 1.75 mm, 2.85 mm, and 3.00 mm. Its internal chamber fits spools up to 210 × 85 mm. A 360° thermal circulation system uses dual heating elements and a bottom fan to spread heat evenly around the material.

Users can set the internal temperature between 35 and 70 °C and the drying time between 1 and 99 hours. A touchscreen manages these settings and includes a memory function for retaining preferred configurations. The unit measures 274 × 265 × 118 mm and weighs 1190 g. Filament can feed straight to a printer during the active drying cycle, allowing continuous operation. It is suited to hobbyists, makers, and educators who need consistent filament conditioning.
