The Sunlu SP2 combines filament drying and storage into one sleek unit – but is it any good? In this video, I go through the specs, assembly, operation, and even run a sponge drying test to see how effective it really is. I also measure power consumption and take a look at its thermal performance with a thermal camera. If you're 3D printing with moisture-sensitive materials, you might want to see how the SP2 holds up.
