Sunlu S4 Filament Dryer

Sunlu S4 Filament Dryer

The SUNLU FilaDryer S4 is an advanced filament dryer designed for demanding 3D printing users. It offers a large capacity to dry up to 4 spools (1 kg each) simultaneously and supports operation with multiple printers at once. With a power output of 320-330 W, rapid heating (up to 50°C in just 30 minutes), and a maximum temperature of 70°C, the device ensures effective and uniform drying of even the most demanding materials such as PA or PC. The built-in humidity control system, touchscreen interface, 8 filament outputs, and predefined material profiles make the device both effective and highly convenient to use.

Dry up to 4 filaments simultaneously - maximum productivity

Thanks to the large chamber (450 x 210 x 211 mm), you can dry up to four filament spools at the same time. This is ideal for multicolor printing or working with multiple printers simultaneously. It eliminates downtime for material changes, streamlining and speeding up the entire workflow.

Instant heating and high power - efficiency that makes a difference

The device features a PTC heater with up to 330 W power, enabling it to reach 50°C in about 30 minutes and a maximum of 70°C. This reduces filament preparation time and improves drying efficiency, allowing even hygroscopic materials to regain their properties quickly.

Ideal temperature balance - perfect drying for every spool

A three-fan system (located on the sides and bottom) ensures even air circulation and maintains temperature stability within 3°C. This guarantees uniform drying of all filament sections, resulting in better print quality, greater consistency, and reliable operation.

Smart humidity control - filament always in perfect condition

An advanced humidity control system automatically initiates drying when humidity exceeds the set range (30-50%) and stops the process once optimal conditions are reached (approximately 25%). This full automation ensures the filament is always ready for use without manual monitoring.

Safety and ease of use - technology you can rely on

The SUNLU S4 includes a triple safety system: a PTC heater, a temperature sensor, and software protection. It monitors temperature in real time and alerts users to any abnormalities, ensuring safe operation. The touchscreen and preset profiles for PLA, ABS, PETG, TPU, PA, and PC simplify operation and eliminate guesswork in settings.

Full compatibility and flexibility - tailor the equipment to your needs

Supporting filament diameters of 1.75 mm, 2.85 mm, and 3.00 mm, and compatible with most 3D printers, the SUNLU S4 adapts well to any environment. Eight filament outputs and the ability to connect multiple printers simultaneously allow flexible workstation configurations, expanding your creative capabilities without limits.
