Investigating UV Exposure and Thermal Cure in Vat Photopolymerization

NETZSCH Photo DSC Vat Photopolymerization

During the Vat Photopolymerization process, the component is built-up in layers in a liquid resin vat using a UV laser beam to selectively cure the resin. Learn how the degree of thermal cross-linking of a two-component resin is determined by the preceding cross-linking reaction during photo-polymerization.

Investigating Dual Curing Resins for Digital Light Synthesis (DLS) with the Photo-DSC 204 F1 Phoenix

CLIP-NETZSCH-PhotoDSC

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.

Kinetic Study for Additive Manufacturing

NETZSCH_DLS_Optimized

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.
