Implicit Function-Based Modeling of Lattice Structures for Lightweight Design

Conventional CAD tools face challenges with lattice structures due to the geometrical complexity and numerous facets of STL digital models typically used in additive manufacturing workflows, prompting the need for alternative methods. This paper introduces a function representation-based approach to model uniform lattice structures using a 1D wireframe model followed by surface triangulation. The study highlights the efficiency of generating lattice structures using this method compared to other techniques available in the literature and traditional boundary representation. Unlike traditional methods, this approach removes the necessity for boundary representations of lattice structure models, resulting in more efficient data management. The findings of this research have significant implications for the development of lightweight 3D components optimized for additive manufacturing and their representation in CADs. This method is designed for industrial applications where rapid and efficient design of complex geometries is essential for achieving lightweight components.
