Butenediol vinyl alcohol copolymer based filament for Fused Filament Fabrication. Printing complex designs may only be possible with temporary support structures. Ultrafuse BVOH water-soluble support filament has been designed to easily dissolve in water. The solubility is increasing with higher water temperature. It offers great compatibility to a variety of materials: PLA, PRO1, ABS, ABS Fusion+, PA and PAHT CF15. Store this monofilament in a sealed bag or container to prevent moisture uptake.
