PVA (Poly Vinyl Alcohol) is a very unique water-soluble print material. Its solubility in warm water makes it an ideal support material, though it can also be used as a model material for special projects. Unlike competitive brands of PVA, ours is made from a grade that is suited ideally to 3D printing due to its increased temperature tolerance and better melting behavior. As with all of our other materials, our PVA is produced to exacting tolerances and is professionally packaged with a large quantity of high-performance desiccant to ensure that it gets to you dry and ready to print. Please note that PVA is very moisture sensitive and as such should always be kept sealed with desiccant while not in use. PVA also requires lower extrusion temperatures to avoid charring within the print head.
