Polyvinyl alcohol (PVA) is a soft, biodegradable polymer that is sensitive to moisture. When exposed to water, PVA will dissolve, which makes it a useful support structure material for 3D printing. When printing complex shapes or ones with partially enclosed cavities, PVA supports can be used and removed by placing them in warm water, where they will dissolve. Standard supports may have been difficult to print or remove in these situations. PVA can also be used as a model material if you need to make quick prototypes
