PVA (Polyvinyl alcohol) is a water-soluble thermoplastic, widely adopted as a support material for FFF 3D printers. Optimized for the FFF manufacturing process, our PVA is compatible with most of BCN3D filaments and can be easily printed to create the support and then dissolved with ordinary water.

PVA 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.

 

Properties:

- Water-soluble supports for partially enclosed cavities and complex geometries

- Sacrificial moulds

- Exceptional adhesion with PLA

- Great  combination with PET-G, TPU and Nylon

 

You can purchase PVA from our store: BCN3D PVA

Build plate adhesion: Magigoo

Apply a fine and unified layer of Magigoo glue to achieve a good adhesion between the 3D printed part and the printing surface of your 3D printer in order to keep the part fixed.

It is best to apply Magigoo when the printing bed is cool.

 

Recommendations:

Plastics absorb moisture from the air. For long periods of time without printing, it is
recommended to keep the PVA spools in a box or airtight container with desiccant
to keep them dry.

Filament Storage

PVA emits low levels of gasses and particles when printed. We recommend printing
it in a well-ventilated area to ensure a healthy environment.

Note: Check the issues when using humid PVA.
