Computational Design of Architected Lattices for Construction Applications

Abstract

Architected lattices have been utilized in aerospace and research applications for their modularity, scability, reconfigurability, and high strength-to-weight properties. However, voxels have yet to find widespread integration in the residential or commercial construction industry because of the industry’s distinct system needs. This study identifies the pain points unique to the construction industry that have slowed or disabled the adoption of new practices, highlighting the importance of utilizing known materials, methods, and the transparency of the design process, as major hurdles to adoption of innovation in the industry. This study presents a computational approach to designing architected lattices that seeks to undermine these core issues by making building with architected lattice structures agnostic to material and manufacturing methodology. Three open source computational approaches to architectural design are proposed: 1) integration of support structures for additively manufactured structures; 2) parametric design of voxels from 2D material, their manufacturing molds, and optional alignment features; and 3) generation of two-dimensional cut files for assembly with 3D printable joinery. These files are computationally designed and arranged for instantaneous production to demystify the lattice architectural design process, establish a pathway for utilizing all available materials in lattice construction, reduce the overhead costs for experimentation with lattice structures, and eliminate barriers to the fabrication process by enabling accessible manufacturing methods.
