BVOH (Butenediol Vinyl Alcohol Co-polymer) is an advanced water-soluble support material for complex multi-extrusion 3D prints. BVOH bonds to nearly all ‘build materials’ and it dissolves in water at a faster rate than PVA support materials. Its thermal stability is optimized to eliminate any risk of your hot-end clogging up due to thermal degradation.

General guidelines for 3D printing with support materials like PVA and BVOH

Printing with support materials, in general, isn’t plug and play and does require a fair amount of 3D printing expertise as there isn’t a generic one-size-fits-all setting for multi extrusion 3D printing with PVA and/or BVOH filaments. The optimal 3D printing settings for support PVA and BVOH filaments can even vary between the same models of 3D printers.

One of the most common challenges is to establish a good bond between the PVA and/or BVOH support material and the primary build material. Below parameters are of utmost importance to establish good bonding between the 3D printing materials.

Verify the extrusion distance between the printed object and the support material.
Typically the default setting in most slicer software is set at an extrusion distance of 0.1 – 0.2mm, which is optimal for break-away support materials. For water-soluble support materials, we recommend turning this setting down to 0.0mm.
The displayed printing/nozzle temperature should be accurate.
If the temperature deviates up to or over 10°C from the intended printing temperature, this may negatively impact the flow of your support material. How big this deviation is wildly varies depending on the printer you’re using.
Make sure your printer is properly leveled. Avoid height differences across the multiple nozzles.
To verify your nozzles are leveled, we recommend 3D printing a small rod (e.g. 5cm x 1cm with PLA) and switching nozzles every 1 – 2 layers to detect any imperfections in the layers.
