Abstract: Traditional kinetic energy dissipation systems, such as automotive shock absorbers and sports suspension elements, rely heavily on isotropic materials and hydraulic dampers that exhibit uniform mechanical responses regardless of the load orientation. This limitation often results in inefficient energy absorption during multi-axis or oblique impacts, potentially transferring hazardous forces to the payload or operator. This project presents the design, fabrication, and evaluation of a novel 3D-printed mechanical metamaterial featuring tunable structural anisotropy for direction-dependent shock mitigation. Utilizing custom-engineered cellular lattice topologies, the proposed structure is optimized to maintain high stiffness and load-bearing capacity under pure compressive vertical loads, while exhibiting a controlled, energy- absorbing "snap-through" buckling failure mode when subjected to off-axis or lateral impact vectors. Finite Element Analysis (FEA) is utilized to model the stress distribution and deformation behavior of varying unit-cell geometries. Prototype matrices are fabricated via Additive Manufacturing (AM) and subjected to multi-axis mechanical testing. The results demonstrate a highly customizable energy management system capable of redirecting and attenuating impact forces based entirely on geometric intelligence, offering a solid-state, maintenance-free alternative for aerospace, automotive, and personal protective equipment applications.
