SUNLU FilaDryer S4 - Filament Dryer

The SUNLU FilaDryer S4 4-Spool Filament Dryer is a storage and conditioning unit for FDM 3D printing setups. It holds multiple spools at once to reduce moisture-related problems such as clogging and poor layer adhesion. The dryer works with hygroscopic materials like PLA, ABS, PETG, TPU, PA, and PC. Filament routing feeds material directly to compatible FDM 3D printers during drying. The unit has a black-and-white exterior and weighs 4,800 g.

At 516 × 278 × 350 mm, it provides the internal volume needed to house the spools. A triple-fan airflow system ensures even heat distribution. It supports filament diameters of 1.75 mm, 2.85 mm, and 3.00 mm. Users can adjust drying parameters and monitor internal conditions while it runs. Multiple ports on the exterior allow connection to several printers at once, making the setup suitable for workshops that need continuous printing across different materials.
