Polyvinyl alcohol
Possible Support material, can maybe extruded with the standard extruder.
Polyvinyl alcohol (PVOH, PVA, or PVAL) is a water-soluble synthetic polymer (not to be confused with polyvinyl acetate, a popular wood glue).
PVA is fully degradable and is a quick dissolver. PVA has a melting point of 230°C and 180–190°C for the fully hydrolysed and partially hydrolysed grades, respectively. It decomposes rapidly above 200°C as it can undergo pyrolysis at high temperatures.
