摘要： A three-dimensional part is printed using an additive manufacturing technique. The three-dimensional part includes an outer wall having an outer surface defining a shape of a part and in interior surface defining an interior cavity. The part includes a plurality of first sections having a plurality of printed layers, each printed layer of the first section having a plurality of wall segments that form triangle shaped cells wherein each of the plurality of first sections are attached to the interior surface of the outer wall. The part includes a plurality of second sections having a plurality of printed layers, each printed layer of the second section having a plurality of wall segments that form hexagram shaped cells of hexagons and triangles, wherein each of the plurality of second printed sections are attached to the interior surface of the outer wall and wherein the first and second sections are in an alternating pattern, wherein when adjacent printed layers of the first and second sections are printed a wall segment of a cell defining a triangle bisect the hexagon shaped cell.
