Moist filament is a common cause of poor-quality prints—it can show up as stringing, worse adhesion, nozzle clogging, or an imperfect surface. The Sunlu Fila Dryer S1 Plus reliably dries filament and helps restore its optimal properties, making printing more stable and the resulting models stronger and more visually appealing.
The dryer offers precise temperature settings in the 35–55 °C range and drying time settings from 0–24 h (default 6 h). Typically, 3–6 hours is enough to significantly improve print quality, depending on the material type and ambient conditions. Thanks to the design with internal rollers, you can print and dry at the same time, which saves time and keeps the filament in ideal condition throughout the entire print.
The device supports up to 99% of commonly available spools (max. Ø210 × 85 mm) and standard filament diameters 1.75 / 2.85 / 3.00 mm. Operation is intuitive with two buttons and a clear LCD display, while the quiet operation won’t disturb you even in a home workshop or office.
