Patent ID: 7963085

Claim:
A truss structure comprising: N number (N>1) of vertically stacked three-dimensional space filling layers, wherein each of said three-dimensional space filling layers comprise: an array of out-of-plane truss units, said units comprising at least three leg members, said legs being connected to each other at an upper node, and each leg terminating at a lower node distal from said upper node; said truss units connecting to nearest laterally adjacent units at lower nodes; said three-dimensional space filling layers having a top side and a bottom side; wherein: at least a portion of said top side of each of said three-dimensional space filling layers for the first through (N th −1) layers comprises a top adjoining region; at least a portion of said bottom side of each of said three-dimensional space filling layers for the second through (N th ) layers comprises a bottom adjoining region; and wherein each of said three-dimensional space filling layers are discretely bonded to immediate vertically adjacent three-dimensional space filling layers, wherein said discrete bonds are formed between the top adjoining region of one layer and the bottom adjoining region of an adjacent layer.
