HAVM: Designing 3D Hybrid-Anisotropic-Voronoi Cells for Microstructured Metamaterial

We introduce a novel class of hybrid-anisotropic microstructures governed by a set of fully geometric-driven parameters, enabling comprehensive top-down control for cell shape, orientation, density, hybridity (open and closed configurations), and thickness. To realize this, we develop a computational framework that transforms the designed parameter space into Voronoi-based micro-tessellations for 3D hybrid-anisotropic cell structures. The numerical simulations and physical experiments are across multiple objectives, i.e., stiffness, strength, and weight. These results are obtained using only a single base material, demonstrating the versatility and applicability.
