Direct stereolithography fabrication of ceramic and metal components is reviewed with emphasis on progress made toward three important aspects of the technology: 1) the physical/mechanical properties achievable, including the range of materials that can be utilized; 2) the dimensional accuracy of the process, including the level of surface roughness; and 3) the process economics and delivery times achievable. Strength data on a variety of stereolithography fabricated metal and ceramic components is summarized. Dimensional accuracy and surface roughness issues are discussed and a cost analysis for fabricating two representative ceramic partis is presented.
