The best solution for drying filaments
As 3D printing technology advances, the need for efficient filament drying is growing. In response to this demand, we proudly present the all-new SUNLU FilaDryer S4 – designed to deliver optimal drying and improved print quality.

More than just bigger
The SUNLU FilaDryer S4 has a spacious design of 458 × 218 × 312 mm , and can hold up to four rolls of 1 kg filament at a time. It is equipped with eight filament outlets and included PTFE hoses , so you can dry multiple filament types and simultaneously print with multiple 3D printers – all at once.

More than efficiency
The FilaDryer S4 uses a powerful PTC heating element in combination with three fans , which ensures fast and even heating. It reaches 70 °C in a short time. With a heating power of 330 W , it delivers 6.9 times higher performance than the previous model, the SUNLU FilaDryer S2.

More than just temperature
FilaDryer S4 not only regulates the temperature, but also controls the humidity . The built-in ventilation circulates the heat efficiently via the three fans and maintains a temperature balance within ±3 °C . The eight outlets ensure that humid air is efficiently discharged, preventing condensation and moisture accumulation – so that the selected temperature matches the actual temperature inside the drying chamber.



Preset temperatures for popular filament types
SUNLU FilaDryer S4 comes with pre-configured temperature settings for the most commonly used filaments such as PLA, ABS, PETG, TPU, PA and PC . These settings are based on extensive test data and ensure optimal drying time and temperature for each material.
By expanding capabilities while reducing the need for manual setup, FilaDryer S4 makes it easier than ever to achieve better and more stable printing results – no matter what filament you use.
