Ceramic stereolithography (SLA) was used to fabricate a ceramic. A ceramic 3D printer based on the SLA method was manufactured. In order to systematically and effectively evaluate the role of the parameters in the ceramic green body, the orthogonal test method is introduced. The placement position of the parts, the laser repetition frequency, and scanning speed are used as independent variables to be studied. The final result shows that when laser power is set, the relationship between the hardness of the part and the position of the part is not evident. The speed of laser scanning greatly influences the mechanical properties of the parts. Alumina parts with smooth surface and dense microstructure were obtained after debinding and sintering processes.
