Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices
True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key
