| Abstract Scope |
Lattice structures are cellular structures composed of periodically arranged unit cells with a high strength-to-weight ratio and remarkable properties like lightweight, energy absorption, and vibration resistance. Owing to their superior mechanical performance and properties. With the development of additive manufacturing technology, more complicated shapes and architectures of prototypes can be made for end-user products.
The paper discusses the advantages and disadvantages of lattice structures and suggests ways to overcome limitations. The study uses seven structures, including BCC, Octahedron, and Cross-cube, as well as three structures composed of two of them and one structure composed of three, to analyze the relationship among the structures. The compression strength and physic-based finite element simulations were performed to analyze the quantitative relationship between the structures and the mechanical response. The results can help in the design and improvement of products made with lattice structures. |
