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.
