PVA Filament

Polyvinyl Alcohol

B
Also known as:Polyvinyl AlcoholBVOH
Family:Water-soluble supports

Why Use PVA?

  • Dissolvable support for complex geometry (especially with PLA/PETG depending on pairing)
  • Cleaner overhangs and internal channels

Things to Consider

  • Very moisture sensitive; quickly becomes unusable if left out
  • Slower printing; can clog if wet or overheated
  • Requires careful pairing (supports must adhere to the model material but still release/dissolve well)
