A new class of high-performance resins are available for additive manufacturing with the introduction of Digital Light Synthesis (DLS) technology. In combination with Continuous Liquid Interface Production (CLIP), DLS uses ultraviolet light and oxygen to continuously grow objects from a pool of resin instead of printing them layer-by-layer, subsequently increasing the printing speed and the mechanical performance. For many DLS resin systems, a secondary thermal curing step is required in order to reach the final material properties after printing. This step is a major limiting factor in the production time of the DLS process, as materials may require several hours of thermal post curing. The aim of this study is to optimize this secondary curing cycle for the epoxy-based resin EPX 82 by reducing the thermal curing time while avoiding a negative influence on the final mechanical properties. Differential scanning calorimetry (DSC) was used with different heating rates and a chemical reaction model was developed. The Di Benedetto relationship was used to include diffusion control for high degrees of cure. Based on the kinetics study, an optimized curing cycle was generated using different maximum conversion rates and heating rates. The results show that it is possible to reduce the thermal curing cycle time by more than 9 h (73 percent) compared to the supplier recommendation while maintaining the mechanical properties of the final part.
