Abstract

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