Ultrafuse BVOH is a high-performance water-soluble support filament designed for dual-extrusion 3D printing. Made from a butenediol vinyl alcohol copolymer, it dissolves quickly and cleanly in water, enabling easy removal of complex support structures without damaging the main print. Compatible with a wide range of engineering filaments such as PLA, ABS, PET, TPU, and Nylon, Ultrafuse BVOH offers excellent printability, reduced brittleness compared to traditional PVA, and reliable adhesion to build surfaces. Ideal for producing intricate geometries and functional prototypes requiring soluble supports.
