The Sunlu SP2 filament dryer combines heating with storage for 3D printing materials in an airtight container. The heating base and container can be used together or separately, and the containers can be stacked to save space. It features a display and a built-in hygrometer for monitoring the humidity inside.

The temperature can be set from 35 °C to 70 °C. The 200 W PTC heater is supported by a fan, an overheat protection switch, and software-based temperature control. In storage mode, the internal humidity can be maintained at around 25% when the ambient humidity is approximately 50%. The carry handle, recessed base, and three cable ports on each side make it easy to move and connect to different printing setups.
