PVA-M filament is our preferred, cold water soluble, supporting material for dual extruder 3D printing. The modification on the raw material results in a filament that is much more thermally stable than a regular PVA. It also bonds well to PLA, ABS and PET-G, which enlarges the application field significantly. This polyvinyl alcohol-based filament is non toxic and biodegradable once dissolved in water. Easy printing, much less failures and easy removability makes this the supporting material you should try.
PVA-M features:
• Improved formula with enhanced stability in printing
• Excellent water solubility
• Thermally much more stable than a regular PVA
• Good bonding to PLA, PET-G and ABS
• Biodegradable when dissolved in water

Colours:
PVA-M is available in its natural colour.
For specific applications PVA-M is available in colours on request.
Packaging:
PVA-M 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.
Additional info:
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-M dissolves in cold water. Higher water temperature (up to 70˚C is no problem) will accelerate the dissolution.
PVA-M 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.
