Ceramics materials are widely used in various fields due to their exceptional properties such as heat resistance, chemically stable and good mechanical properties. For the development of advanced ceramics, the demand for sophisticated ceramics structures with desired properties has been increasing. Additive manufacturing is deemed as a rapid moldless, prototyping manufacturing method that enables the fabrication of complicated ceramic components. However, after the shape-forming process, the subsequent sintering process is important to obtain a rather dense sintered structure exhibiting desired properties, and preferably, at lower sintering temperature to reduce the load on the environment. In this study, using an electrostatic assembly method, controlled formation of ceramic composite particles and the feasible design of composite particles with different core and additive particles was demonstrated. The feasible improvement of the sintering process using the green body obtained using ceramic composite particles via a stereolithography method will also be reported.
