ABSTRACT

An effective method for 3D lattice structure design is proposed using the volumetric distance field (VDF) based on analytic shape functions. By the innovative synthesis of lattice structure and VDF-based Boolean operations, a variety of computational models with intricate exterior shape and arbitrary lattice structure can be constructed. The significant advantage is that this design method can be easily applied to design highly complex lattice structure models. The important parameters such as the cell type and the size of lattice structure are controllable in customized MATLAB program. Design results verify that the presented design method is efficient to generate 3D models with required lattice structure.
