BVOH

Butenediol Vinyl Alcohol Co-polymer

BVOH (Butenediol Vinyl Alcohol Co-polymer) is an advanced water-soluble filament used exclusively for support structures in multi-material printing. It dissolves cleanly in water, leaving complex prints free of support marks without any manual removal. More moisture-resistant and easier to print than traditional PVA, BVOH is the premium choice for intricate overhangs and complex geometries.

Ease of use: Moderate

This filament is moderately demanding to print. Worth watching: it can be moisture-sensitive.
