BVOH (Butenediol vinyl alcohol copolymer) is a water-soluble thermoplastic optimized for the FFF manufacturing process. Our BVOH extends the compatibility with most of BCN3D filaments and can be easily printed to create the support and then dissolved with ordinary water.
In comparison with PVA, BVOH supports allow to achieve better surface quality, to orientate the part to get better mechanical properties and even to print multi-component models and mechanisms with a fastest dissolution and easier to remove.

 

Properties:

- Watter-soluble material

- Great combination with PLA, Tough PLA, PET-G, TPU 98A, ABS, PA and PAHT CF15

- Fastest dissolution

-Easy to remove inside small parts

- Less clogging issues

- Highly hygroscopic

Printing surface adhesive:  Magigoo

Apply a thin and uniform Magigoo layer in order to have a good adherence between the printing surface and the print.

Not only does it provide good adherence, but it also helps prevent glass wear and chipping. This phenomenon is due to the adhesive physically preventing the glass from deforming as the material contracts.

The best option is to apply Magigoo when the printing surface is cold.

Tips:

Plastic absorbs humidity from the air. For long periods of time without printing, it is recommended to keep BVOH in a box or an airtight container with desiccant so they remain dry. The Smart Cabinet is your best friend when it comes to filament stocking. It maintains a suitable temperature and humidity conditions to ensure the best performance.

 

Note: Check the humid BVOH printing issues and how to properly store it  Filament storage.

 

BVOH emits nearly no dangerous particles and fumes when it is being printed. We recommend you to print in a well-ventilated area to ensure a healthy environment.
