摘要： Products and methods are provided for additive manufacturing of products in a collapsed state for post printing expansion in preparation for use in their intended application. A product includes interconnecting members configured for forming by printing in a collapsed state, with joints between the interconnecting members configured for relative movement of the interconnected members from the collapsed state to an expanded state. The interconnecting members define a larger package size in the expanded state than in the collapsed state. The joints are freely moveable in the collapsed state and are locked in place in the expanded state.

摘要： 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.

摘要： A method to manufacture a ceramic foam filter includes: sintering a filter body to a temperature greater than a molten metal to be filtered through the body; creating multiple tortuous path channels extending through the filter body individually having a repeated and controlled passage geometry creating a continuously changing diameter and area of a flow path through the multiple tortuous path channels causing localized increases and decreases in molten metal flow rate through the multiple tortuous path channels; and applying a mixture of at least one ceramic powder and at least one binder using additive manufacturing to shape the filter body including the multiple tortuous path channels.
