Gembird PVA is a special water-soluble filament designed primarily for printing support structures on complex models. Thanks to its unique property - water solubility - it allows easy removal of supports without any mechanical intervention that could damage the final model.

Key features

PVA (polyvinyl alcohol) is a thermoplastic material that fully dissolves in lukewarm water at 50-60 °C. It is mainly used with PLA printers with dual extrusion, where it serves as a support material for models with complex geometry, overhangs, or internal cavities. The filament has a highly accurate round structure with a tolerance of ±0.05 mm, ensuring stable feeding and even extrusion throughout the entire print. PVA is biodegradable and environmentally friendly.

This filament will be appreciated by users of dual 3D printers who need to print models with demanding geometry - complex mechanical parts, figurines, prototypes with internal channels, or parts with large overhangs. It combines ideally with PLA material. It finds application in design workshops, prototype studios, among modelers, and in school environments. After the print is finished, simply immerse the completed print in lukewarm water and the supports will dissolve on their own.

Printing tips

• PVA is a strongly hygroscopic material - before printing, we recommend always drying the filament in a dryer or oven for 6-8 hours at 45 °C.
• Store in a sealed package with silica gel, ideally in a dry box with humidity below 20 %.
• Do not overheat the nozzle above 225 °C - PVA degrades and can clog the nozzle.
• For faster dissolving, the water can be gently stirred or warmer water can be used (max. 60 °C).
• Before a longer break in printing, remove the filament from the extruder to prevent heat degradation.
• Use primarily as a support material in dual extrusion, not as a standalone build material for the final part.
• After dissolving, let the model dry well to remove any residues of dissolved PVA.
