Material Science in Additive Manufacturing: What are Thermosets?

Thermosets offers many opportunities for innovative composite manufacturing. Knowledge about the material science of thermosets is crucial as there are some challenges in producing 3D-printed parts at high rate and high quality. Learn more!

Thermosets are used in the Additive Manufacturing technologies such as Vat Photopolymerization and Digital Light Synthesis (DLS) as well as Material Jetting and Binder Jetting. While the material offers many opportunities for innovative composite manufacturing, thermosets are highly cross-linked and irreversibly cured, which can represent challenges in producing 3D-printed parts at high rate and high quality. Therefore, knowledge about material science is crucial.

This week’s topic: Material Science of Thermosets

  • Deep dive into the molecular structure and chemical reaction
  • Relationship between cross-linking density and material properties (glass transition, stiffness, end use temperatures)
  • Important properties when working with thermosets

Photopolymers used in the Additive Manufacturing technology Digital Light Synthesis (DLS) are challenging materials. Little is known so far about the consequences of increased temperatures, e.g., due to higher room temperatures. A research paper aims to investigate the influence of temperatures on such dual-curing resins and finds that the Photo-DSC is most effective in tracking the thermal conversion as well as to identify optimal exposure times.
