Abstract Scope |
Advancements in polymer science and additive manufacturing (AM) have significantly impacted the development of mechanical metamaterials, enabling the fabrication of microstructures with unique behaviors such as auxetics or mechanical cloaking. Despite these advances, a comprehensive design and fabrication framework is absent which restricts the practical application of metamaterials. Our research introduces an inverse design tool that leverages a novel, multi-modulus polymer chemistry to create modular 2D metamaterials approaching the theoretical limits of linear elasticity. We utilize topology optimization (TO) to design unit cells that serve as the building blocks for more complex metamaterials. Our TO algorithm accounts for manufacturing process effects, such as polymer diffusion, effectively turning manufacturing constraints into design advantages. We successfully demonstrate the production of metamaterials with spatially varying Poisson’s ratios and Young’s moduli. This approach not only simplifies the design and fabrication process but also makes advanced metamaterial design accessible to a broader audience. |
