Abstract
In some aspects, described herein are methods of additive manufacturing in which one or more corrugated layers are incorporated into the three-dimensional (3D) object. Also provided herein are 3D objects that can include one or more corrugated layers.
Claims21
A method of additive manufacturing, the method comprising:
- forming a corrugated layer of material using a three-dimensional (3D) printer, wherein the corrugated layer has a thickness, a length, a width, and a height,
- wherein the corrugated layer has a cross-sectional area defined by the thickness and width at any given point along the length of the corrugated layer, and
- wherein the corrugated layer varies in height along the length of the corrugated layer, and wherein the height of the 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.
A three-dimensional laminate object having a corrugated layer produced via an additive manufacturing process comprising:
- forming a corrugated layer of material using a three-dimensional (3D) printer, wherein the corrugated layer has a thickness, a length, a width, and a height,
- wherein the corrugated layer has a cross-sectional area defined by the thickness and width at any given point along the length of the corrugated layer, and
- wherein the corrugated layer varies in height along the length of the corrugated layer, and wherein the height of the corrugated layer at least at one 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.
