The laser powder bed fusion process enables the manufacturing of intricate shapes, including lattice structure metamaterials.These structures consist repeating unit cells, formed by nodes connected struts within space.In this study, various cell designs were fabricated in Ti6Al4V, maintaining consistent relative density, and subsequently tested under uniaxial compression loading.The results highlight differences mechanical responses failure mechanisms between designs.The findings reveal that face-centered cubic exhibits better properties, yield stress, elastic modulus, peak absorbed energy, comparison to body-centered structures.This study provides valuable insights into optimizing design for enhanced performance LPBF-fabricated Ti6Al4V components.

Abstract Auxetic metamaterials refer to materials and structures with extraordinary deformation, i.e., transverse expansion (contraction) under uniaxial tension (compression). In recent decades, a very wide range of innovative functional performance has been discovered stemming from this behavior. This desirable exhibition adaptivity, programmability, functionality provides great potential in soft intelligent systems. However, thus far, the mainstream research on auxetic focused subjective design, monotonic mechanical properties, passive tunability. review thorough overview classical properties applications, primary objective proposing new roadmap auxetics for advances interdisciplinary field. The fundamental works are categorized different configurations mechanisms. particular, integration shape morphing, actuation, sensing, multiphysical response, inverse design is reviewed detail. To accelerate development smart structural systems, applications generalized into robotics (outside body), human–machine interaction (surrounding healthcare devices (inside body). Finally, several significant topics emphasized theory, material choice, manufacturing technique, applications.
