Abstract:

A structure can include a body having a first surface and a second opposing surface. The three-dimensional structure can include the body defining a first pattern of first cavities extending into the body from the first surface and the body defining a second pattern of second cavities extending into the body from the second surface. One or more first cavities can eccentrically intersect with one or more second cavities to define a pattern of apertures in the body.
