An article of manufacture includes a cellular structure having one or more layers that are dispensed in a viscous form. Each of the one or more layers have a plurality of walls that define an array of cells, the array of cells being arranged to create a non-uniform relative density and/or cell geometry across a width and/or a length of the cellular structure, the width and the length being oriented substantially orthogonally to a depth of the cellular structure.

A method of producing a cellular structure via an additive manufacturing technique includes the steps of: providing a feedstock material to an additive manufacturing printer device; dispensing the feedstock material from the printer device; and controlling the dispensing of the feedstock material to form at least one layer of the cellular structure according to a first predetermined gradient. In some aspects, the cellular structure comprises an array of cells surrounded, respectively, by walls, and arranged to create a non-uniform relative density and/or cell geometry across a width and/or a height of the cellular structure. An article of manufacture produced by such methods includes a cellular structure configured to produce a controlled collapse with selectable dynamic stiffness characteristics by altering the distribution and geometry of cells within the cellular structure, while being able to maintain a substantially similar static stiffness characteristic.
