Cerium oxide (ceria) is well-known for applications in various fields, e.g., as a surrogate for plutonium oxide, and understanding the working mechanisms of stereolithography of ceria will help advance nuclear fuel technology. This investigation is focused on the effects of modulating process parameters for additive manufacturing of ceria ceramics with stereolithography using a CeraFab 8500. A 3 × 3 parametric study has been designed with intentions of mapping the effects of process parameter alterations of 3D printed ceria. Characteristics such as grain size, porosity, stoichiometry, and density will be used to compare printed samples with traditionally processed and sintered ceria. Main parameters varied are powder particle size, solid loading of the slurry, and sintering temperature. The aim of the study is to bound the process window of printable ceria with predictable variations in density and microstructure. We will present our early results, datasets, and interpretations.
