| Abstract Scope |
Technical ceramics have exceptional high-temperature mechanical properties, but their brittleness makes the fabrication of complex shapes challenging. Additive manufacturing techniques, such as Direct Ink Writing (DIW), enable the manufacture of parts with complex shapes, as well as architected materials characterized by geometrical features with controlled defect populations. However, expanding DIW methods to new systems is non-trivial due to changes in powder rheology and suitable printing parameters. Here, we develop a method to screen the mechanical behavior of new ceramic systems using DIW and investigate the effects of different defects produced during manufacturing on the mechanical behavior. First, we synthesize variants of an alumina-based ceramic system. Then, we manufacture single tracks of those systems using DIW and perform characterization and mechanical testing. Finally, we incrementally scale up to arrays of lines to track the evolution of defects in complex builds and investigate the role of these defects on their mechanical behavior. |
