PVOH - Polyvinyl alcohol

PVOH (Polyvinyl Alcohol, also called PVA) is a water-soluble support material. It is used to print support structures when producing cantilever parts.

Depending on the materials and angles of inclination, it becomes necessary to use support brackets to maintain stability and good performance of the printed part. PVA is sensitive to moisture and heat.
