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
- Dissolved in water
- Waste can be disposed with household effluent (*)

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:
period. PVA-M works with most of the common adhesives.
The speed at which the product dissolves in water is dependent on the volume of the printed object, the amount and
the temperature of the water. Higher water temperature (up to 70˚C is no problem) will accelerate the dissolution.
Keep in account that the temperature of the water is based on the properties of the material that you are printing with
PVA-M to avoid warping issues. (example, if you print PLA with PVA-M, keep the water around 40°C).
PVA-M can be used on most Dual printing 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. If you remove the
spool out of the vacuum bag packaging and you do not store it in a room with low moisture content, we advise you to
properly dry the material before printing to avoid any quality issue.
