PolyVinyl Alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer (not to be confused with polyvinyl acetate, a popular wood glue).

Great as a support material. Maybe even more usefull then HIPS since it can be dissolved in water instead.

It's the same material as many packaging chips are made from but then without foaming it



Maybe these chips can be recycled into filament?
