Overview of the proposed cellular frameworks; (a) top and side views of a unit cell, (b) schematic of the multilayered construction, (c) photograph of structure fabricated by additive manufacturing, comprising 5 × 5 × 4 unit cells in x, y, z coordinates with components made of either nylon or ABS resins. In the x-y view, the red and blue markers correspond to a unit cell and 4.5 × 4.5 unit cells, respectively. In the x-z view, the red and blue markers correspond to 1 × 2 unit cells and 3 × 4 unit cells, respectively.
