Abstract
A method includes building an article by a layer-by-layer additive manufacturing process. While the article is being built, a solid outer wall is formed. An inner structure of the article is integrally formed with the outer wall. The inner structure includes an internal permeable structure.
Claims20
A method comprising:
- building an article by a layer-by-layer additive manufacturing process;
- forming, while building the article, a solid outer wall of the article;
- and
- integrally forming an inner structure of the article with the outer wall, wherein the inner structure comprises an internal permeable structure.

A component comprising:
- an external structure, built by layer-by-layer additive manufacturing, and defining an external surface of the component;
- and
- an internal structure, built by the layer-by-layer additive manufacturing, and comprising a matrix structure, honeycomb structure, or lattice structure, the internal structure integrally formed to the external structure and positioned within the component to provide structural support, vibration dampening, heat transfer, energy absorption, fluid flow, or piping to the component.
A method comprising:
- designing a component having an external structure and an internal structure, wherein the internal structure performs at least one of vibration dampening, structural support, heat transfer, energy absorption, fluid flow, or piping, and wherein the internal structure includes at least one of a matrix structure, honeycomb structure, or lattice structure, the internal structure integrally formed to the external structure;
- creating digital files defining the component on a layer-by-layer basis;
- and
- producing the component by layer-by-layer additive manufacturing using the digital files.
