Abstract

This paper introduces a novel methodology for designing optimized components with lattice structure infill. The lattice unit cells are generated through an algorithm that enables continuous variations in topology, and are thoroughly characterized using a numerical implementation of Asymptotic Homogenization. The resulting effective material properties and their gradients are interpolated to create geometry-dependent scaling functions, enabling efficient use of gradient-based optimization schemes. The approach is both fast and robust, capable of handling complex 3D structural problems with high computational efficiency. Thanks to specific features of the unit cell generation algorithm, the resulting heterogeneous lattices are inherently printable, making the method particularly suited for real-world additive manufacturing applications.
