Absolutely! PLA is hygroscopic, meaning it absorbs moisture from the air. Wet filament can cause various issues during printing, such as oozing, poor adhesion, and inconsistent extrusion. It is essential to dry wet PLA filament before using it. After you dry PLA, store it in a dry box or a sealed container with moisture-absorbing agents like silica gel to maintain its dryness and avoid UV degradation. Proper storage extends your filament's lifespan and ensures optimal results for your 3D printing projects.
