Abstract:
This research focuses on optimizing resin formulations for Masked Stereolithography (mSLA) 3D printing to enhance vertical resolution and reduce curing time. The study explores the effects of varying the compositions of monomers, crosslinkers, and photoinitiators on the polymerization kinetics and mechanical properties of the resin. Methyl methacrylate and butyl acrylate were selected as monomers, bisphenol A ethoxylate diacrylate and polyethylene glycol diacrylate as crosslinkers, with Irgacure 819 chosen as the photoinitiator. The optimized formulation, which includes 2 wt% butyl acrylate in a mixture of 40 wt% polyethylene glycol diacrylate, 60 wt% bisphenol A ethoxylate diacrylate, and 0.1 wt% Irgacure 819, achieved a curing depth of 3.82 ± 0.100 mm and a Shore D hardness of 40.8 ± 1.79. This optimized resin demonstrated exceptional 3D printing resolution, with relative difference (RD) values below 3.5% for complex geometries, outperforming the commercial Jamghe High Clear resin in both speed and accuracy. The results highlight the significant potential of resin formulation optimization in mSLA printing, offering the ability to reduce processing times while improving print fidelity. These advancements suggest that the proposed resin formulation could be a viable solution for high-resolution, rapid fabrication in industrial and commercial 3D printing applications.
