ROSA3D-PVA 1,75mm Natural 0,5kg

ROSA3D-PVA Support material

PVA filament, also known as polyvinyl alcohol, is a type of thermoplastic material that is perfectly suited for use as support material during the printing of complex models from other materials such as PLA, PET-G, TPU, or PA. This allows for the entire model to be printed in one go, eliminating the need for printing in parts, their assembly, or even rendering some designs impossible.

After completing the print, the model simply needs to be submerged in warm water that does not exceed the thermal deformation temperature of the filament. The time required for the supports to dissolve depends on the size of the model and the amount of PVA used, typically ranging from several minutes to several hours. Agitating the water in the container can expedite this process.

Printing with PVA is done at low temperatures, on an open system printer, without a heated bed. Due to its tendency to absorb moisture, the filament should be stored in tightly sealed packaging with a moisture absorber, away from direct sunlight, at a temperature between 15°C and 25°C, to maintain its quality for longer periods.

Recommended printing parameters:

• Extrusion temperature: 190-215°C
• Bed temperature: 50-70°C
• Printing speed: 20-50 mm/s
• The filament can be printed on unheated beds. In case of adhesion issues, it is recommended to use an adhesion agent. Cooling the print is advised, and its intensity should be adjusted according to the capabilities of the printer and the geometry of the printed model.
