PVA is quickly soluble in water, bonds well to plastics and prints easy. Therefore it is an excellent supporting material for dual extruder 3D printing. This polyvinyl alcohol-based filament is non toxic and biodegradable once dissolved in water. For applications other then supporting material PVA @df is also available in colours and has a high tensile strength.

PVA Features

  • Excellent water solubility
  • Easy to print at low temperature
  • Good bonding to various plastics such as PLA and ABS
  • Biodegradable when dissolved in water
  • Limited smell

Additional info

Recommended temperature for heated bed is ± 35-60˚C. Do not exceed a printing temperature of 225˚C, because then PVA crystallizes quickly and it will no longer flow and/or dissolve in water.

The speed at which the product dissolves in water is dependent on the volume of the printed object and the temperature of the water. PVA @df dissolves in cold water. Higher water temperature (up to 70˚C is no problem) will accelerate the dissolution.

PVA can be used on all common desktop FDM or FFF technology 3D printers.

Storage

Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
