Intralattice is an open-source plugin for Grasshopper designed to generate solid lattice structures within a 3D design space. Developed as an extensible alternative to commercial solutions, it serves as a valuable research tool for multi-scale design and optimization. The software enables engineers to:, - Reduce volume and weight while maintaining structural integrity., - Increase surface area to maximize heat transfer., - Generate porosity in bone scaffolds and implants., - Serve as a platform for structural optimization., By providing full access to the source code, Intralattice encourages exploration of lattice design at a deeper level to engineer better products.
