BVOH (Butenediol vinyl alcohol copolymer) is a water-soluble thermoplastic optimized for the FFF manufacturing process. Our BVOH extends the compatibility with most of BCN3D filaments and can be easily printed to create the support and then dissolved with ordinary water. In comparison with PVA, BVOH supports allow to achieve better surface quality, to orientate the part to get better mechanical properties and even to print multi-component models and mechanisms with a fastest dissolution and easier to remove.
