Ultrafuse BVOH • Water-Soluble Support

Need clean supports for overhangs, hollows, and complex geometry? Ultrafuse BVOH is a water-soluble support filament that dissolves in water, faster when the water is warm, so you spend less time on post-processing than with breakaway supports. What's Included 1 × spool of Ultrafuse BVOH (Natural), in the diameter and spool size you select Sealed packaging to help protect this moisture-sensitive filament Print Settings Nozzle: about 190–210°C (start near the middle of the band and tune) Bed: about 60–100°C (glass bed preferred) Speed: about 30–60 mm/s Nozzle diameter: 0.4 mm or larger Dry before printing if the spool has taken on moisture: about 60°C for 4–16 hours in a hot-air dryer or vacuum oven Keep the spool sealed between jobs; BVOH is moisture sensitive Material Butenediol vinyl alcohol copolymer (BVOH) water-soluble support filament Available in 1.75 mm and 2.85 mm Spool sizes: 350 g and 750 g (select at checkout) Natural colour Forward AM compatibility (as stated by the manufacturer): PLA, PRO1, ABS, ABS Fusion+, PA, and PAHT CF15 Manufacturer claims dissolve rate about 2× faster than other PVA in water; warmer water speeds dissolution further How Support Works Print Ultrafuse BVOH as temporary support under overhangs, bridges, and internal cavities After the print finishes, soak the part in water so the support dissolves away Warmer water dissolves support faster; rinse until the soluble material is gone Compared with breakaway support, you get less manual scraping and cleaner surfaces on complex or hollow parts Good To Know Store sealed in a dry place. Open air and humidity will degrade printability Dry the spool if you see stringing, bubbling, or weak support adhesion Run support settings suited to soluble material (lower density interface layers help rinse time) Match your model material to the Forward AM compatibility list above for best results Good For Parts with steep overhangs that need temporary support Complex geometries and interlocking features Hollow or enclosed cavities where breakaway tools cannot reach Jobs where you want less post-processing than snap-away support
