Material Science in Additive Manufacturing: Understanding Curing Behavior of Thermosets

Thermosets are irreversibly hardened by curing. Learn about the two distinct ways of curing thermosets, which are used in Additive Manufacturing processes.

Previously, we have explained the molecular structure of thermosets and how the cross-linking density and the resulting material properties are connected. Thermosets are irreversibly hardened by curing. In Additive Manufacturing (AM), two distinct ways of curing thermosets are employed: UV curing and thermal curing.

This week’s topic: Curing of Thermosets

  • Difference between UV curing and thermal curing with examples from Additive Manufacturing
  • Different chemical reaction types: Radical and Cationic Photopolymerization
  • What are Interpenetrating Polymer Networks and why are they important in AM?

Photopolymers have gained increased importance in many industries. Digital Light Synthesis (DLS), an Additive Manufacturing Technology, is a prime example for the usage of photopolymers, because it wouldn’t be possible without these materials. Learn why the NETZSCH Photo-DSC offers a proven method to optimize the Additive Manufacturing process. Read the article here!
