Abstract: Dynamic cellular microstructure designs customize production in an additive manufacturing construction. A seamless mesh generated from an input shape, based on available scans and/or surface designs, is supplemented with curvature data derived from the input shape. Redesign of a base shape and/or group of base shapes within a seamless mesh enable customization in localized areas of the seamless mesh. The seamless mesh may also be retopologized according to localized feature attractor points. Base shape redesign includes cellular replication, subdivision, growth, and/or modification to adjust variable material properties. Modification changes relative opacity, stretch, drape, compressive strength, plasticity, yield strength, resilience, and Poisson's ratio specific to geometry of a base shape. Each base shape can also exhibit modifiable isotropic or anisotropic properties.
