Filling Application

Accura® Bond and Accura® Patch are materials designed to use on printed SLA QuickCast parts to fill and seal vent and drain holes.  It can also be used with all 3D Systems Accura materials to repair cracks on patterns that are damaged, chipped or have other surface  defects. Once cured, the material is hard and adhered with the SLA printed part. The Accura® Bond or Accura® Patch material can be sanded to match the surrounding surface.
