Free Form Fabrication of Ceramics by Stereolithography
During this grant, we showed that stereolithography can directly fabricate ceramic green bodies from ultraviolet (UV) curable solutions which contain dispersed ceramic powders. We demonstrated SLA of silica, a model refractory for metal casting molds, and SLA of alumina, which is promising for structural ceramics. Viscosity control for these highly concentrated suspensions and cure depth behavior were the main issues for fabricating a ceramic using stereolithography techniques. These ceramic SLA suspensions were evaluated in a stereolithography machine, and three-dimensional parts were built. Part building parameters, Dp and Ec, were determined for this suspension. Layer adhesion and subsequent processing resulted in good ceramic parts.
