BVOH

Advanced

Butenediol Vinyl Alcohol Co-polymer

Premium water-soluble support material. Dissolves faster than PVA, adheres better to PETG and other materials, and is more thermally stable. Significantly more expensive than PVA.

⚠ IMPORTANT: Dry Your Filament Before Every Print

All filaments — including BVOH — absorb moisture from the air. Printing with wet filament causes stringing, bubbling, weak layer adhesion, and poor surface finish. This is the single most overlooked cause of bad prints.

Always dry your filament per the manufacturer's recommendations printed on the spool label before printing, especially if the spool has been open for more than a few days or stored in a humid environment. Read our complete filament drying guide →

About the Temperatures & Speeds Listed Below

The print temperatures and speeds shown on this page are general industry ranges — not a one-size-fits-all prescription. Every printer brand and model has different capabilities. A Bambu Lab X1C can print PLA at 500 mm/s; an Ender 3 with a Bowden extruder performs best at 40–80 mm/s.

Always follow your specific printer manufacturer's recommended settings and the temperature range printed on your filament spool label. Start at the lower end of the range and dial in from there.

Best For

  • Dissolvable supports for PETG
  • PLA
  • and other primary materials in dual-extrusion setups
  • complex geometries requiring clean support removal

Avoid For

  • High-temperature environments

Pro Tips

  • 01Must store and print from sealed dry box with desiccant; extremely hygroscopic
  • 02Configure slicer to use BVOH only for interface layers, not entire support structure
  • 03Reduce extruder idler tension slightly to avoid crushing filament

Print Speed by Printer Tier

Print speeds vary dramatically by printer. The speeds listed in product specs (like "500 mm/s") are maximum capabilities — not recommended everyday speeds. Use this table as a general guide and always follow your printer manufacturer's recommended settings.

High-End (Bambu X1C, P2S, H2D)
Print Speed: 150–300 mm/s

High-acceleration direct-drive systems. Follow manufacturer slicer presets.

Mid-Range (Bambu A1/A1 Mini, Prusa MK4, Creality K1)
Print Speed: 60–150 mm/s

Good performance at moderate speeds. Follow slicer presets for best results.

Entry-Level (Ender 3 series, Bowden extruders)
Print Speed: 30–60 mm/s

Start slow and tune up. Follow your printer manufacturer's recommended settings.
