The SUNLU FilaDryer S4 is a large-capacity filament dryer designed for users working with multiple materials, colours or 3D printers simultaneously. It can accommodate up to four 1 kg filament spools at once and allows filament to be fed directly to up to four 3D printers while drying. The powerful PTC heating system, three-fan air circulation and temperatures of up to 70 °C provide uniform drying, while automatic humidity control helps keep filament in optimal condition during both printing and long-term storage.
