Filament Dry Box A filament dry box is a container designed to store 3D printer filament in a controlled, low-humidity environment. It prevents the filament from absorbing moisture, which can degrade print quality by causing bubbles, inconsistencies, or weak layers. Dry boxes often include desiccants, humidity sensors, and sometimes heating elements to actively dry filament during storage. They are particularly useful for moisture-sensitive materials like nylon, PVA, and PETG. Proper filament storage in a dry box extends the lifespan of the filament and ensures consistent printing results, especially in humid environments. |
