| Abstract Scope |
Drawing inspiration from biological structures found in nature, this study explores the potential for creating materials characterized by high damage tolerance and resistance to crack propagation. Specifically, mammalian enamel microstructures serve as a model for the development and production of high-strength ceramic materials using a direct ink writing 3D printing process. The intricate decussated rod and band pattern observed in dental enamel is known for imparting exceptional fracture resistance and strength. Based on X-ray synchrotron tomography images, computer-aided design files are generated employing an implicit modeling approach via nTop software. Three-point bend test samples featuring a banded microstructure are then 3D printed using alumina and yttria-stabilized zirconia photoresins on a Hyrel 30M printer equipped with a 405 nm light source. This research seeks to advance the understanding of bio-inspired material design and manufacturing techniques for applications requiring robust and resilient materials, such as advanced energy systems. |
