PVA
The ideal filament for support structures
PVA (Polyvinyl alcohol) is a cold-water-soluble 3D printing filament with strong adhesion, particularly with PLA, PETG, and TPU filaments. Its strong adhesion makes it an ideal support material for various filaments. Support material is usually necessary for printing models with complex geometry. The PVA support will dissolve in a water bath leaving behind a smooth 3D printed part.
