The article details the latest design and implementation of a stereolithography (SLA)
based technique, Fluid Interface Supported Printing (FISP). The FISP technique involves
printing from a thin resin layer above a static, immiscible support fluid. The support fluid
prevents deflection of overhanging geometry by providing a buoyant force equal to that of the
gravitational force due to the minute density difference between the support fluid and cured
resin. Complex curing and shrinkage dynamics are a primary knowledge gap. A COMSOL
multiphysics simulation model was developed to simulate the curing process, including
volumetric light intensity and optimized parameters for chemical reaction kinetics. The article
presents a pathway for further enhancing and validating the simulation model.Mechanical Engineerin
