Claim 4:
5. A method of making a trim article, comprising:
printing an outer casing having inner and outer surfaces, wherein the inner surface surrounds an interior portion;
printing a core portion within the interior portion of the outer casing, wherein the core portion includes a first lattice matrix having first and second sides and a first pattern of interconnected links defining a first set of cells positioned between the first and second sides of the first lattice matrix, wherein the first side of the first lattice matrix is coupled to the inner surface of the outer casing, and further wherein the first lattice matrix further includes a second pattern of interconnected links defining a second set of cells positioned between the first and second sides of the first lattice matrix; and
printing a second lattice matrix having first and second sides and a third pattern of interconnected links defining a first set of cells positioned between the first and second sides of the second lattice matrix, wherein the first side of the second lattice matrix is coupled to the second side of first lattice matrix, and further wherein the second side of the second lattice matrix is coupled to the inner surface of the outer casing, and further wherein the second lattice matrix includes a fourth pattern of interconnected links defining a second set of cells positioned between the first and second sides of the second lattice matrix, and further wherein the second lattice matrix includes an overall density profile that is greater than an overall density profile of the first lattice matrix, and further wherein the outer casing and the core portion are comprised of a single material.
