The Sunlu FilaDryer S4 revolutionises filament preparation for 3D printing. With its enormous capacity for up to four spools simultaneously and powerful PTC heating technology, it ensures that your filament is always in perfect condition. Eliminating moisture-related problems such as stringing, bubbling and poor layer adhesion has never been easier - ideal for users of multi-material systems and large format printers.

Key features:

Large capacity: the interior can hold up to 4 standard spools (1kg) at a time. The design is perfectly optimised to feed multiple printers or multi-material setups in parallel.

Powerful PTC heating: A 330 W PTC heating element ensures a significantly faster heat-up time and more efficient drying compared to conventional models (approx. 50 % time saving).

Intelligent humidity control: The integrated humidity sensor monitors the climate inside. In Smart mode, the appliance switches on again automatically when the humidity exceeds a defined value, keeping the filament permanently dry.

Printing while drying: The device has 8 filament outputs (2 per spool position) so that you can print directly from the drying box.

Versatile compatibility: With an adjustable temperature of up to 70 °C, the S4 is suitable for a wide range of materials, including PLA, PETG, ABS, PC, TPU, PA (nylon) and carbon fibre reinforced filaments.
