Abstract

These scripts present an efficient method for designing struct-and-node lattice structures for industrial applications. Traditional computer-aided design tools struggle with lattice structures due to the high complexity and many facets typical of digital models, necessitating alternatives. An approach based on function representation is usually adopted for triply periodic minimal surface lattices but not for strut-and-node lattices, which are the topic of this study. The proposed method defines the base unit cell geometry using function representation primitives and operations, followed by triangulation and spatial replication for both uniform and graded lattices. Unlike conventional techniques, this method eliminates the need for boundary representations of lattice structure models, leading to more efficient data handling. The results of this research have broad implications for developing lightweight 3D components optimized for additive manufacturing. The approach is intended for industrial applications where designing complicated geometries quickly and efficiently is necessary to achieve lightweight components.
