enhancement over conventional 3d printed lattice structures and investigation of their mechanical properties using fem modeling and experimental studies

The introducing of 3d printing has revolutionized the design and fabrication of different complex lattice structures, offering unprecedented flexibility in optimizing mechanical properties for various applications. however, conventional 3d-printed lattice structures often face some limitations in achieving the desired balance between strength, stiffness, and weight. this study presents a comprehensive investigation into the enhancement of conventional 3d-printed lattice structures through innovative design modifications. by integrating advanced computational techniques such as finite element method (fem) modeling with experimental studies, this study aims to evaluate the mechanical performance of these enhanced structures. the fem analysis allows for precise prediction of stress distributions and deformations under compressive loading conditions, while experimental validation provides insights into real-world applicability and performance. the results show that, weight is not the main factor that affects the mechanical specifications, which was the study’s major hypothesis through the results obtained, it was indicated that reducing the weight by 12% in the modified model compared to sc-fcc show that, the modified model which weight 10.32 g lighter than sc-bcc which weight 11.7 g and better strength with 2% if compared with sc-bcc lattice structure. the findings reveal significant improvements in mechanical properties, including increased load-bearing capacity, demonstrating the potential of these enhanced lattice structures for advanced engineering applications. this study not only contributes to the understanding of the mechanical behavior of 3d-printed lattices but also paves the way for the development of more efficient and robust structural components.
