Moisture controlled 3D Printing Filament Storage Cabinet

Moisture absorption in filaments could be a significant cause of failure in 3D printing

Eureka ADL-3D77 3D Printing DryCabinet is the perfect humidity-controlled solution for filament storage. Our automatic humidity-controlled filament dry box will provide a quick and simple way to store filament without hassle. Simply set the desired humidity level, store your filaments and our dehumidifier will take care of the rest. Your filament will stay completely dry, easily accessible, perfectly identifiable (i.e. no need to open every box to find the right kind of filament you are looking for) and filament stays dry and ready to be used anytime you need them for a print.

3D Printing Filament Storage Dry Cabinet features:

Low humidity environment

Four filament feed ports allowing direct printing from the cabinet while in dry storage.

Adjustable hanging rod hanging up to 33 cm diameter spools.

Airtight cabinet prevents moisture and dust.

Low energy consumption (13 W Avg., 100 W Max).

No consumable parts, desiccants to replace, no water tanks to empty.

 

Effects of Moisture Absorption by 3D Printing filament material may result in the following problems:

Brittleness and breakage of filament,

Diameter inconsistency

Hissing steam or bubbling when filament reaches the hot-end,

Filament degrading or lose tensile strength,

Higher extruding temperature

Moisture Sensitivity of Filament Material

Filament polymers are known to absorb moisture which will affect the quality of your print. Whether you use Nylon, PVA, PETT, PLA, PC or ABS or other exotic material filaments, keeping these filaments dry in a humidity-controlled environment is critical to a successful print.

Our Dry Cabinet ADL-3D77 features <20%RH storage environment, suitable for maintaining most filaments in optimal moisture content levels to produce a great print.

The water molecule’s boiling point is approximately 100 °C. Depending on the type of filament material, the extrusion temperature ranges from 160 °C to 250 °C. So any presence of moisture in the filaments will produce steam and bubbles, causing interference with the flow of plastic out of the hot end and creating unwanted pockets within the finished object.

Storing your 3D printing filaments in a humidity-controlled dry box will prevent moisture absorption and eliminate flow interference at the hot end. 

Some filament materials (like nylon, and PVA) are more hygroscopic than others, which means it has an inherent quality to attract ambient moisture. If filament spools are exposed to ambient humidity for long periods of time without any storage solution in place, moisture-related problems will soon appear during printing. A complicated project could take hours or even days to complete. When a project has been set to run on its own, the discovery of problems is often too late. Moisture absorbed in the filament could cause obstructions to the printer’s hot end and may require it to be replaced. Furthermore, moisture absorption can also affect the tensile strength of the filaments and the output objects.

By consistently storing your 3D printing filaments in our dry cabinet, you will eliminate any moisture absorption in those hygroscopic filaments during the printing and long term storage process.
