Recommended drybox

Some printing strings, technically called filaments, have the ability to absorb moisture in the air. This property is called hygroscopy. When such a wetted filament passes through the hot nozzle of a printer, the water it contains turns to steam. This causes small bubbles to form in the printed material and disrupts the smoothness of the print. The consequence is poor print quality, which is manifested, for example, by a rough surface, inaccuracies or so-called 'waviness', where the printer leaves thin strands of plastic where it shouldn't. At the same time, the mechanical strength of the model is reduced because the layers are less easily adhered to each other. It is also possible to hear cracking or hissing from the nozzle during printing and, in extreme cases, moisture can lead to nozzle clogging. A drybox is a device designed to store filament in a low humidity environment. It is essentially a sealable box that prevents access to ambient moist air. Inside there is usually a moisture absorber, usually silica gel, which keeps the internal environment dry. The drybox is thus used not only for precautionary storage of new filament spools, but also for drying material that has already absorbed moisture. Some materials such as PETG, nylon or TPU are more sensitive to moisture than others, but even with commonly used PLA, dry storage will ensure more stable and predictable print results.
