Abstract: A method to manufacture an automobile vehicle engine aluminum piston, comprises: printing an aluminum piston crown portion including an additive manufacturing (AM) piston crown work piece using initial aluminum powders defining an initial aluminum powder bed; removing the aluminum piston crown portion from the initial aluminum powder bed; fixedly joining a cast iron ring carrier to the AM piston crown work piece; placing the aluminum piston crown portion together with the cast iron ring carrier into a secondary and a tertiary aluminum powder bed; and printing a piston skirt integrally connected to the AM piston crown work piece and to the cast iron ring carrier.

Abstract: Systems and methods for manufacturing a product include a mixing station for preparing a solution containing a base material and a performance modifier. The base material is configured to deliver performance characteristics of the product that are preselected and the performance modifier is configured to enhance the performance characteristics. An encapsulation station produces particles of the performance modifier in a coating of the base material as an encapsulate powder. An additive manufacturing cell includes an energy source and is used to build the product from the encapsulate powder by an application of energy from the energy source.
