Abstract
A three-dimensional part printed using an additive manufacturing technique, which includes sets of printed cell layers, each defining an array of hollow cells with wall segments, and sets of printed transition layers, each being disposed between adjacent printed cell layers, where the sets of printed transition layers each comprise sloped walls that diverge from a first portion of the wall segments and that converge towards a second portion of the wall segments to interconnect the hollow cells of adjacent printed cell layers, and where the sloped walls of adjacent printed transition layers have printing orientations that are rotated from each other in a build plane.
