BigRep’s BVOH support material is an ecologically friendly advanced water-soluble filament that eliminates post-processing for 3D printed parts. Created for use with dual-extruder printers, BVOH can be used in tandem with any other material to provide efficient support. It has been optimized for improved melt flow, eliminating concerns of hotend clogging that come with other soluble filaments.

Due to BVOH’s ability to support heavy prints and the support-removal post-processing it eliminates, it’s ideal for printing complex, ready-to-use prototypes and objects with large overhang or otherwise complex geometries.

BVOH easily dissolves in water – dissolving faster in higher temperatures – cleanly freeing parts from support structures without manual post-processing.
