The Sunlu SP2 filament dryer is designed for anyone who wants full control over their filaments—from drying to long-term storage. The heated base efficiently removes moisture, while the airtight container with a silicone seal helps maintain a stable environment even after drying ends. In storage mode, it can keep internal humidity at approximately 25% (with ambient humidity around 50%).
The large chamber holds 2× 1 kg spools, or 1× 2 kg or 1× 3 kg spool (max spool size 250 × 153 mm). The SP2 is compatible with 1.75 mm and 2.85 mm filament diameters and supports common materials such as PLA, PETG, ABS, TPU, and more. Dehumidified filament helps reduce typical issues such as stringing, nozzle clogging, or weak layer adhesion.
