MOWIFLEX is a water soluble support material for additive manufacturing based on FFF (fused filament fabrication) processes to achieve maximum freedom in object design. For best printing results please follow the printing guidelines below.
Handling and storage
MOWIFLEX is soluble in cold water, which makes it inherently sensitive to moisture. It was designed to be as little moisture sensitive as possible and can be used at a relative humidity of < 50 % for several days to weeks without problems. However, if not used MOWIFLEX filament should be stored in a moisture tight aluminum laminated bag with some desiccant.
MOWIFLEX is sensitive to overheating, thus the nozzle temperature should not exceeded 225°C and during printing with the main material the temperature of the support material nozzle should be lowered to <170°C. To guarantee optimum adhesion to the main printing material, a reduced printing speed should be used for the interface layers.
The optimum printing parameters might vary depending on the printer and software.
To dissolve the support structures in water it is recommended to use an agitated water tank at slightly elevated temperatures (ca. 30-40°C). MOWIFLEX will also dissolve at room temperature and without agitation, but dissolving will take much longer. Afterwards, the solution can be disposed of conveniently through normal waste water systems due to the biodegradable nature of polyvinyl alcohol. For disposal of large quantities please follow local regulations.
