Over the course of your 3D printing journey, your filament can degrade and become wet, due to the natural properties of filament that make it absorb water like a sponge. This can damage prints, resulting in poor quality outputs from any 3d printers. Certain plastics are more resistant than others to this fate, but a filament dryer is imperative to maintain good quality prints on some materials.

For filament drying, there are lots of solutions ranging from ready made options to DIY solutions.
