摘要

The lattice structure is made up of struts or curved beams that connect at various points. These connectors are essential for transmitting forces and preserving the overall stability of the structure. One of the main benefits of lattice structures is the exceptional strength-to-weight ratio. Lattice structures are advantageous for applications that rely on for weight reduction because of this property. The mechanical and physical characteristics of uniform lattice structures and triply periodic minimal surfaces (TPMS) have been extensively studied in the literature. These structures, whose characteristics have been thoroughly investigated, are made up of regular repetitions of a single type of lattice. However, hybrid lattice structures which combine at least two different lattice types can give even more desirable characteristics like stiffness, compressive strength, and Young’s modulus. In this work, a novel method for creating a hybrid lattice has been presented. This approach will be utilized to design a complex hybrid lattice and create models using material extrusion technology. In this study, the manufacturability, the mechanical properties, and energy absorption capacities of the hybrid lattice will be evaluated. The results suggest that lattice structure hybridization can enhance energy absorption.
