What is BVOH 3D printing filament?

BVOH (Butenediol vinyl alcohol co-polymer) is a water-soluble material designed to print temporary support structures that can be dissolved in water — cold or warm. Post-processing is faster and easier with cleaner-looking results.

Mechanical Properties

With a tensile strength of 34 MPA, BigRep BVOH is robust enough to fulfill its job as a temporary support structure before removal.

Thermal Properties

BVOH has a relatively low glass transition temperature is 68°C making it easier to print at lower temperatures.

Chemical Properties

BVOH is design to dissolve in water, so naturally it is highly hygroscopic. Warm or agitated water will speed up the dissolving time.

BigRep Quality

BigRep materials are high-quality complete with a Certificate of Analysis to guarantee reliable performance.

Powerful Slicing

BLADE (BigRep's slicer software) delivers complete, easy-to-use solutions for our recommended printer/material pairings.

Made for Large-Format

With spool sizes up to 8 kg, BigRep filaments are optimized for massive 3D prints with complex geometries.

BigRep BVOH compatibility

BigRep believes in being open, so our 3D printers can use any 3D printing filament compatible with the machine specifications. The same goes for our filaments: print BigRep materials on any 3D printer with the appropriate specs.

Featured Application


Custom Car Tuning

AVI Boston creates custom automotive parts like dashboards, audio installations, and door panels. AVI's owner, Safi Barqawi, says “We design and build these intricate parts in-house. We would never be able to do that by hand.” BigRep's water-soluble BVOH allows them to create detailed 3D prints that would be otherwise impossible.
