PVA is a support material. Typically it is used with PLA filament. PVA is best printed around 195 Celsius. When a PLA product is printed out, it can be thrown into water so that the PVA supporting material can be melted away. Cold water would take 4 hours to melt all PVA. Warmer water will melt PVA faster.
PVA is soft, soluble in water under normal temperature.
