| Abstract Scope |
A new technique for top-down Stereolithography (SLA) 3D printing that reduces the need for sacrificial supports is in development. SLA is a popular form of additive manufacturing, which leverages photocurable resin but requires sacrificial support structures for overhanging geometry. Sacrificial supports consume excess time and material, require extraneous post-processing, and reduce overall surface quality. To negate the need for additional support, a fluid interface supported printer (FISP) is being developed. The FISP prints from a thin resin layer above a static, immiscible supporting fluid. Density differences between the support fluid and cured resin prevent deflection from buoyant and gravitational forces. Printing a first layer without a solid support plate presents numerous challenges. Creating a uniform first layer will lay the foundation for more complex multilayer curing. Thus, the current research is directed at improving print quality through experimentation and multiphysics simulation. |
