Framework designed for programmable 3D woven metamaterials

Laura Leay interviews MIT’s Carlos Portela about a computational design framework for deformable woven metamaterials. Graphs describe the periodic architecture and how struts interweave at nodes; user-defined helix geometry controls the woven beams. The framework produces files for finite-element analysis and 3D printing, enabling predictions of large-deformation behavior and fabrication of previously inaccessible architectures. The freely available approach connects textile-inspired design with tunable elastic response.
