What can result from improper filament storage?

Improper filament storage can lead to moisture absorption, which significantly affects the quality of 3D printing. Filaments, especially those made from materials like PLA, ABS, or Nylon, are hygroscopic, meaning they can absorb moisture from the air. When the filament absorbs moisture, it can lead to various printing defects such as bubbling, stringing, and poor layer adhesion during the print process. This phenomenon occurs because moisture within the filament vaporizes during the heating phase, causing the filament to expand and lead to inconsistent extrusion.

In contrast, improved layer adhesion, enhanced flexibility, and a longer shelf life are typically associated with proper storage conditions. Storing filament in a cool, dry environment or using vacuum-sealed bags can help maintain the filament’s quality and performance for a longer time. Thus, understanding the importance of proper storage is crucial for optimal printing results.
