Presented by Tru-Design, Polynt Composites and Composites One, this informative webinar will take attendees from an overview of current polymeric 3D printing to an in-depth presentation of proven finishing methods for enhancing surface cosmetics, ensuring vacuum integrity of 3D printed tools and parts, and filling in defects due to start/stops, bead break-outs, flow issues and air voids. Among these finishing methods are innovative high build coatings that can be more easily machined than the original print material, especially in situations where significant detail, class A cosmetics or post-print modifications are required.

Primary Topics:

  • Surface issues resulting from fast, large format 3D printers
  • How to fix defects and overcome issues
  • Coating options for 3D printed parts, molds and fixtures
  • Thermoset coatings to address CTE concerns in high temperature applications
