| summary |
3D lattice structures are gaining widespread application in multiple design fields. While the number of projects that utilize load-responsive inhomogeneous and anisotropic 3D lattices in design applications increase, accessible and effective algorithmic generation methodologies remain lacking. This paper addresses this gap by introducing a novel computational method for controlled load-responsive inhomogeneity and anisotropy in 3D lattice generation. The presented methods employ a responsive Ellipsoid Packing algorithm informed by the global tensor field of the packing geometry, followed by a Kissing Ellipsoids algorithm to generate the lattice. Load specific anisotropy and inhomogeneity in the ellipsoid packing process is achieved in response to the magnitude and directionality values of the global tensor field and specialized responsive lattices are easily generated. The proposed Ellipsoid Packing workflow is compared to various common lattice generation algorithms. Results show improvement in mechanical performance. |
