PVA @DF 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 is also available in colours and has a high tensile strength.
- 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

PVA is available in its natural colour.
For specific applications PVA is available in colours on request.
PVA is available in nearly any type of packaging and labelling, but will be supplied always in a vacuum bag, due to the moisture sensitivity of PVA. Ask our team to help you customizing your product.
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 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.
Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly.
