Area of Science:

  • Additive Manufacturing
  • Materials Science
  • Polymer Chemistry

Background:

  • Digital Light Processing-based Vat Photopolymerization (DLP-VPP) is a precise 3D printing technology.
  • Thermochromic materials change color with temperature, offering sensing capabilities.
  • Integrating thermochromic properties into DLP-VPP resins is underexplored.
