Additive manufacturing enables the fabrication of lattice structures with complex geometries and customizable mechanical properties. As the capabilities of this technology expand, understanding and optimizing the mechanical performance of different lattice topologies has become increasingly important. In this study, the effect of unit cell variation on the mechanical performance of various lattice topologies (Octet, Dode Medium, Dode Thick, Diamond, Rhombi Octa Light, Body Diagonal With Nodes, and Rhombic Dodecahedron) was systematically investigated. Using the dynamic point tracking method, displacement values at the top left, top right, and center points of each model were measured to assess deformation behavior. The Body Diagonals With Nodes model exhibited the highest displacement values (top left: 43.83 pixels, top right: 46.07 pixels, center: 40.31 pixels), indicating greater deformation compared to the other models. In contrast, the Rhombic Dodecahedron model showed minimal and symmetric displacement (4.24 pixels at both top points), reflecting a more stable structure. These findings demonstrate the critical role of unit cell geometry in determining the mechanical response of lattice structures and provide valuable insights for optimizing lattice designs in advanced engineering applications where stability and deformation resistance are essential.
