The Sunlu SP2 is a modular 2-in-1 filament dryer that combines active heating with airtight storage for 3D printing materials. The unit consists of a heating base and a dedicated storage container that can be stacked to optimize workspace organization.

Drying and Airtight Storage

The heating base removes moisture, while the airtight container with silicone seals helps maintain filament condition after drying. In storage mode, the chamber maintains an internal humidity level of around 25% under average 50% ambient humidity conditions.

Capacity and Compatibility

The chamber accommodates spools weighing from 0.25 kg to 3 kg and supports 1.75 mm and 2.85 mm filament diameters. It can hold two 1 kg spools, one 2 kg spool, or one 3 kg spool up to 250 mm in diameter and 153 mm in width. Operating temperatures range from 35°C to 70°C, making it compatible with PLA, PLA+, PETG, ABS, TPU, PVA, PVB, ASA, and PA/PC.

Practical and Safe Operation

The device features an integrated hygrometer for real-time humidity tracking, a carrying handle, and three filament ports on each side. Reliable heating is delivered via a 200 W PTC heater with fan assist, overheat protection, and intelligent software temperature control.
