Many biological systems have increased mechanical properties due to the presence of functionally graded material. Although the microstructures found in nature are difficult to replicate, mimicking their geometric properties and spatial arrangement may improve the mechanical properties of additively manufactured parts. In this project, we propose that altering directed energy deposition (DED) printing process parameters to create hard geometrically interlocking blocks and softer material between these blocks can improve a part’s ability to dissipate energy.
