PrintDry Filament Dryer
Availability: In stock
Most filaments absorb moisture from the air readily. When moisture content goes up in the filament, the printability goes down and may lead to the filament becoming un-printable. The PrintDry filament dryer is an in-line filament dryer, which is designed to dry and to feed the filament into a 3D printer at the same time.
How it works
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.
Recommended drying time
|No.||Materials||Dryer Temp||Drying Time|
|1||PLA||45°C (113°F)||> 4h|
|2||ABS||60°C (140°F)||> 2h|
|3||PETG||65°C (149°F)||> 2h|
|4||Nylon||70°C (158°F)||> 12h|
|5||Dessicant||65°C (149°F)||> 3h|
These recommendations are made for the following conditions.
* Ambient RH: 50% * Ambient Temp: 20°C (68°F) * 500g (1 lbs) filament spool
Actual drying time for a filament may vary under different environmental conditions as well as the initial water content levels in the filament. In addition to drying prior to 3D printing, drying the filament while printing is always recommended.
How to store filaments after drying?
To prevent the filament from absorbing moisture in the future, always store filaments in air-tight containers or re-sealable bags with some desiccants inside to keep your filaments dry. Please note that desiccants need to be regenerated or activated once a while — basically to dry the desiccant packs from time to time.

* Please note the actual temperature inside a dryer varies due to (1) ambient temperature; (2)location; (3)how many filament spools and desiccant pouches. Higher ambient temperature means higher temperature inside a dryer. More close to the heat source the temperature is higher. Lower chamber of a dryer is about 8C higher than the upper chamber. More filament spools and desiccant pouches inside a dryer can increase the dryer internal temperature.
