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.
Industrial 3D printing processes create functional, end-use parts with mechanically isotropic properties and smooth surface finishes. Read how Prof. Dr. Tim Osswald, Alec Redmann and the team at the University of Wisconsin-Madison worked together with the California-based company Carbon Inc. optimized the thermal curing cycle of EPX 82 resin used in the their Digital Light SynthesisTM (DLSTM) process.
