Description
PVA filament, or polyvinyl alcohol, is a water-soluble thermoplastic. Therefore, it is made to be a support material. Complex prints made of other materials (eg PLA, PET-G, TPU, PA) can be printed with the help of PVA support structures.
On a multi-extruder printer, you can print models that would otherwise require printing in parts, gluing or would not be possible at all! After printing, just immerse the model in warm water (but not too hot, keep the thermal deformation temperature of the actual part in mind). Depending on the dimensions of the model and the amount of PVA used, such a bath may take from several minutes to several hours. Mixing the water in the tank can speed up the dissolution process.
PVA can be printed at low temperatures, in an open printer and on an unheated bed. Due to its hygroscopicity, the filament must be stored in a tightly closed bag or container with a moisture absorber. Storing PVA away from sunlight and at a temperature between 15°C and 25°C will extend its shelf life.
Recommended printing parameters:
- extruder temperature: 190-215°C
- bed temperature: 50-70°C
- print speed: 20-50 mm/s
The filament does not require a heated bed or chamber. In case of problems with adhesion, we recommend the use of an adhesive agent.
It is recommended to enable print cooling. Fan speed should be adjusted to the capabilities of the printer and the geometry of the printed model.
