Abstract

Stereolithography is a type of 3D printing that allows liquid photopolymer resin to be cured into layers that make up a 3D object. Creation of such resins for these purposes can require a significant amount of time to test and develop, and commercial resins also require some amount of testing for printer settings before use. This paper reviews how stereolithography works, the materials used, and experimentation done to compare the resin properties to the determined curing times. Using several commercially available resins, varying base exposure and layer exposure times were used to determine the lowest possible curing time that gave the best results. The ideal curing times were compared to certain properties of the resin to determine key trends and found that viscosity had a significant effect on the curing time. This trend can be used to develop a method of finding the ideal curing times for a resin much faster than current testing methods. Certain aspects of the final samples were also noted, and ideal resin monomers are recommended for flexible or crystalline objects, or simply the fastest curing or production speed.
