BVOH

BVOH is a unique material specially developed for FDM printers with a very high bonding to various build materials such as ABS, ASA, PLA, PET, PA, PC and TPU. BVOH dissolves quickly in water (quicker than PVA) and easy to print. It gives the opportunity to print complex models in high quality. Therefore it is an excellent supporting material for dual extruder 3D printing. This Butenediol Vinyl Alcohol Co-polymer based filament is nontoxic.

BVOH features:

  • Good bonding to various build materials such as:
    ABS, ASA, PLA, PET, PA, PC and TPU
  • Excellent water solubility. Higher solubility than PVA
  • Easy to print at low temperature
  • Helps you by printing specific, complex models
  • Light- and UV-sensitive
  • Waste can be disposed with household effluent (*)

Packaging:

BVOH is available in Mitsubishi Chemical packaging and labelling and you can also choose to use your own brandname. BVOH will always be supplied in a vacuum bag, due to the moisture sensitivity of PVA. Ask our team to help you customizing your product.

Additional info:

Recommended temperature for heated bed is >60˚C. Do not exceed a printing temperature of 230˚C for a prolonged period. BVOH works with most of the common adhesives.
The speed at which the product dissolves in water is dependent on the volume of the printed object, the amount and the temperature of the water. Higher water temperature (up to 70˚C is no problem) will accelerate the dissolution. Keep in account that the temperature of the water is based on the properties of the material that you are printing with BVOH to avoid warping issues (example, if you print PLA with BVOH, keep the water around 40°C).
BVOH can be used on most Dual printing desktop FDM or FFF technology 3D printers.
(*)This material is not fully biodegradable but can be disposed of through the household drain with an excess of water.

Storage:

Cool and dry (15-25˚C) and away from UV light. This enhances the shelf life significantly. If you remove the spool out of the vacuum bag packaging and you do not store it in a room with low moisture content, we advise you to properly dry the material before printing to avoid any quality issue.
