A water-soluble PVA filament

Polyvinyl alcohol (PVA) is a water-soluble synthetic polymer hydrolyzed from polyvinyl acetate. It's recyclable and nontoxic and is a quick dissolver. It is primarily used as a dissolvable support-structure material when used with a dual extruder. It can also be used to make dissolvable molds for casting.

The printing temperature can range from around 170-190 degrees Celsius.

As PVA is a water-soluble material, it must be kept dry!
