Abstract
An automotive structural component includes a lattice structure. The lattice structure defines a plurality of cells. The plurality of cells include a multitude of at least partially filled cells each at least partially filled with a filling, and a multitude of hollow cells distributed amongst the multitude of at least partially filled cells to distribute and direct load.
Claims15
An automotive structural component comprising:
- a lattice structure defining a plurality of cells having a multitude of at least partially filled cells each at least partially filled with a filling, and a multitude of hollow cells distributed amongst the multitude of at least partially filled cells to distribute and direct load, wherein the multitude of at least partially filled cells form at least one first row and the multitude of hollow cells form at least one second row disposed adjacent to the at least one first row, and wherein the at least one first row is a V-shape.
A method of forming an automotive structural component comprising:
- additive manufacturing a lattice structure defining a plurality of cells having a multitude of at least partially filled cells, and a multitude of hollow cells distributed amongst the multitude of at least partially filled cells to distribute and direct load, wherein the multitude of at least partially filled cells form at least one first row and the multitude of hollow cells form at least one second row disposed adjacent to the at least one first row, and wherein the at least one first row is a V-shape.
