Devices that use additively manufactured connectible unit cells are described in which each unit cell comprises materials and voids. The materials occupy a certain volume of the unit cell with the voids occupying the balance of the volume. The unit cells form a lattice structure, which exhibits smooth transitions between each of the adjacent unit cells. The lattice structure exhibits periodicity along one (1), two (2), or all three (3) dimensions. The materials have a thickness that is a function of the material location within the device. 1. A three-dimensional (3D) article of manufacture , comprising: [ [{'br': None, 'i': x', 'y', 'y', 'z', 'z', 'x, '0=cos()sin()+cos()sin()+cos()sin(), wherein, 'x is a first dimension;', 'y is a second dimension; and', 'z is a third dimension; and, 'materials that occupy positions within a portion of a volume of the unit cell, wherein the positions are defined by, 'voids that occupy a balance of the volume of the unit cell;, 'additively manufactured infinitely connectible gyroid unit cells, wherein each gyroid unit cell consists of substantially smooth transitions between adjacent gyroid unit cells;', 'a first periodicity of the materials along x;', 'a second periodicity of the materials along y;', 'a third periodicity of the materials along z;', 'a linearly varying thickness of the materials along x;', 'a gradually varying thickness of the materials along y; and', 'a gradually varying thickness of the materials along z., 'a lattice comprising the gyroid unit cells, wherein the lattice comprises2.
