Abstract Scope There are increasing applications for additive manufacturing of ceramics in applications that rely on structures engineered at the macro- and mesoscale (e.g. catalyst supports). Design guidelines for the successful manufacture of ceramics with such complex architectures is currently lacking. This study is aimed developing a methodology for predicting the design limitations in additively manufactured ceramics with complex architectures. We utilize indirect Selective Laser Sintering (SLS) of alumina components that contain hollow channels as a testbed. Simple geometries, such as thin walls and holes, were produced and measured with conventional metrology tools. External surface roughness was measured with optical profilometry. Complex geometries, such as internal helices and cellular structures, were then produced and imaged with x-ray computed tomography (XCT) to determine internal feature accuracy. The results were used to map the design-space, which elucidates the output limitations (e.g. minimum hole size) based on inputs (e.g. material composition, laser parameters).
