Claim of US Patent No. 10,117,343

1. A method for forming a three-dimensional structure in a body having a material defining a first surface and a second surface, comprising:removing a first portion of the material from the first surface of the body to define a first pattern of negative space at the first surface; and
removing a second portion of the material from the second surface of the body to define a second pattern of negative space at the second surface, wherein the first pattern of negative space extends from the first surface to a first depth within the body and the second pattern of negative space extends from the second surface to a second depth within the body to form apertures in the three-dimensional structure.
