1. A three-dimensional (3-D) printed chassis structure, comprising:
a wall bounding a hollow portion of the printed chassis structure; and
a plurality of self-supporting stiffening structures coupled to an inner surface of the wall of the printed chassis structure along a plurality of corresponding edge lines,
wherein each of the plurality of self-supporting stiffening structures extends a full distance across the hollow portion in a plane defined by its corresponding edge lines, and
wherein the plurality of self-supporting stiffening structures comprises a first parallel set of stiffening structures, a second parallel set of stiffening structures that intersects the first parallel set, and a third parallel set of stiffening structures that intersects the first parallel set and the second parallel set.
