Advancements in Computational Modeling of Mechanical Properties of TPMS Lattice Structures

Abstract Additive Manufacturing (AM) has revolutionized the fabrication of lattice structures, offering unparalleled customization of mechanical, thermal, and fluid-dynamic properties compared to traditional subtractive techniques. These intricate lattice configurations play a crucial role across diverse industries, such as medical, automotive, and aerospace, serving various functions including lightweight componentry, expansive surface area structures, and robust energy absorption systems. AM’s inherent flexibility allows for the production of highly intricate parts, including periodic lattice structures seamlessly integrated into complex surface geometries, thereby pushing the boundaries of conventional manufacturing methodologies. Within the realm of AM and lattice structure engineering, the utilization of Triply Periodic Minimal Surfaces (TPMS) stands out for its ability to confer unique mechanical characteristics. Recent research has focused on enhancing mechanical properties by introducing density gradients across TPMS lattice structures. However, a critical gap remains in understanding how these innovative designs influence compressive behavior. This study aims to address this gap by conducting a comprehensive comparative analysis of TPMS lattice structures fabricated via AM. Our investigation seeks to elucidate the influence of different TPMS structures on structural response under compressive loading conditions. our aim is to advance the understanding of AM-based lattice structure design and contribute to the development of high-performance components.
