Lattice and Cellular Architecture Design

Lattice and cellular architecture design involves an enormous design space spanning unit cell geometry, cell connectivity, spatial grading strategies, and relative density distributions — each choice affecting mechanical stiffness, energy absorption, thermal conductivity, and permeability in coupled ways. Current approaches are limited to known unit cell families — octet truss, body-centered cubic, gyroid, diamond — with optimization restricted to scaling parameters within these fixed topologies.

Existing lattice design methods select from cataloged unit cells and apply uniform or rule-based grading, missing the potential of novel cell geometries and spatially varying architectures optimized for local loading conditions. Homogenization-based approaches predict effective properties for known cells but cannot generate new unit cell topologies. The design space of possible cellular architectures far exceeds what parametric exploration of established families can cover.
