Design criteria for lightweight lattice structures: balance between relative density and load-bearing capacity

Introduction: Lattice structure makes 3D printing truly unique Lattice Structure is one of the most representative design features of additive manufacturing. By filling the parts with periodic or non-periodic microstructures, the lattice structure can significantly reduce weight while maintaining or even improving mechanical properties. This degree of design freedom that traditional manufacturing cannot achieve is the core value of 3D printing. From lightweight stents in aerospace to bone implants in medical, lattice structures are redefining the boundaries of engineering design. This article will systematically introduce the design of lightweight lattice structure...
