Method of manufacturing a three-dimensional lattice architecture
First Claim
1. A method of manufacturing a three-dimensional lattice architecture with a thickness hierarchy, the method comprising:
- providing a patterned template at at least one of a top and a bottom of a container, the patterned template having at least one raised step over a flat surface;
providing a volume of photo-monomer in the container contacting the patterned template; and
exposing the photo-monomer to collimated light through a mask, the collimated light passing through a plurality of apertures of the mask at a non-perpendicular angle with respect to the mask to form a plurality of angled polymer struts in the photo-monomer at the non-perpendicular angle to form the three-dimensional lattice architecture.

Abstract
A three-dimensional lattice architecture with a thickness hierarchy includes a first surface and a second surface separated from each other with a distance therebetween defining a thickness of the three-dimensional lattice architecture; a plurality of angled struts extending along a plurality of directions between the first surface and the second surface; a plurality of nodes connecting the plurality of angled struts with one another forming a plurality of unit cells. At least a portion of the plurality of angled struts are internally terminated along the thickness direction of the lattice structure and providing a plurality of internal degrees of freedom towards the first or second surface of the lattice architecture.
