Ultimaker PVA Filament (polyvinyl alcohol) is a leading water-soluble support material for multi-extrusion 3D printing. It offers you freedom and convenience: to design complex model geometries that require supports, which dissolve away in tap water.

PVA Ultimaker

PVA (Polyvinyl Alcohol) is a water-soluble material that is often used as a support material, but can also be used to print independently. PVA supports are useful for complex designs where removing support material manually is difficult or impossible, but leaving the part in a water bath overnight will completely dissolve this material.


Ultimaker PVA is at the heart of our market-leading dual extrusion 3D printing experience.

  • Reliable adhesion to PLA, Tough PLA, CPE, and Nylon
  • Non-toxic formula dissolves in regular tap water which can be disposed of safely
  • 100% biodegradable with no hazardous by-products
  • Good thermal stability gives better degradation resistance compared to other PVA filaments


Ultimaker PVA has the following properties:

  • Melting temperature 163 ÂșC
  • Water-soluble support material
  • Dissolves in ordinary tap water


Many applications can benefit from using Ultimaker PVA support material:

  • Parts with complex geometries and internal cavities
  • Concept models
  • Molds


Ultimaker PVA is officially supported by Ultimaker S5 and Ultimaker 3 series 3D printers, using a BB print core. It is supported for dual extrusion with:

  • Ultimaker PLA
  • Ultimaker Tough PLA
  • Ultimaker Nylon
  • Ultimaker CPE

3 steps to dissolve Ultimaker PVA support

1: Submerge

Put your 3D print in cold or warm water depending on the build material.

2: Rinse

After PVA supports are dissolved, rinse the 3D print to remove any excess PVA solution.

3: Dry
