1. A method of additive manufacturing, the method comprising:
forming an object comprising a plurality of laminated corrugated layers of material using a three-dimensional (3D) printer, wherein each of the corrugated layers of the plurality of laminated corrugated layers has a thickness, a length, a width, a height, and a roll ranging from 0 degrees to 180 degrees, wherein the roll of one or more corrugated layers of the plurality of laminated corrugated layers is varied along the length of the one or more corrugated layers,
wherein each corrugated layer of the plurality of corrugated layers has a cross-sectional area defined by the thickness and width at any given point along the length of the corrugated layer, wherein the cross sectional area of each corrugated layer of the plurality of laminated corrugated layers is substantially the same, and wherein the cross-sectional area of each corrugated layer of the plurality of laminated corrugated layers is substantially constant along the entire length of each of the corrugated layers, and
wherein each corrugated layer varies in height along the length of the corrugated layer, and wherein the height of each corrugated layer at a position along the length of the corrugated layer is greater than the height of a planar layer that can be formed using the 3D printer having the same thickness and width as the corrugated layer, wherein the height of the corrugated layer is measured along the build direction of the 3D printer.
