PrintDry

After absorbing moisture from the air, the water molecules are bound to the polymer chains of filaments. The PrintDry filament dryer uses heat to cause the molecules in the filament to move more vigorously and this weakens and breaks the bond of water molecules from the polymer chains and permits water molecules to move freely. Airflow carries heat to the filament and also carries the freed water molecules away. However, filaments do not dry instantly. They must first be heated to allow the water molecules free movement. Then, there must be sufficient time for the water molecules to defuse to the surface of the filament in order to evaporate. The PrintDry filament dryer is designed based on these drying factors: (1) heat; (2) dew point; (3) drying time; (4) airflow. (click here for the science behind it)
