Abstract: Methods for manufacturing three-dimensional objects using an additive manufacturing technique, methods for forming dye-infused feed material for an additive manufacturing technique, and vehicles including additive manufactured components are provided. An exemplary method for manufacturing a three-dimensional object using an additive manufacturing technique includes solubilizing a dye into a medium in the form of a supercritical fluid and contacting a feed material with the medium to infuse the dye into the feed material to form dye-infused feed material. The method further includes locally melting the dye-infused feed material in selected regions of a layer corresponding to a cross-section of a three-dimensional object being formed and solidifying the dye-infused feed material into a solid layer of dye-infused material. Further, the method includes repeating the local melting and solidifying steps to form the three-dimensional object made up of a plurality of solid layers of dye-infused material.

Abstract: 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.

Abstract: A passively activated flow control device including a valve body configured to be mounted in a vehicle. The valve body includes an inlet and an outlet. A valve member is arranged at the valve body for selectively opening and closing flow between the inlet and the outlet. The valve member is responsive to acceleration induced forces on the vehicle to shift from one of an open configuration and a closed configuration toward the other of the open configuration and the closed configuration.

Abstract: A tubular structure comprises a first end and a second end, a cylindrical outer structure, and at least one inner cavity defined by the cylindrical outer structure and the first and second ends. The first and second ends each include a recess and a cap press fit within the recess. The caps provide a connection point for the ends of the tubular structure. Each end includes a vent in fluid communication with the inner cavity during manufacturing of the tubular structure, prior to insertion of the caps. An isotropic internal support structure extends longitudinally between the ends within the cylindrical outer structure and defines an oil flow channel extending through the tubular structure, each cap includes a cap orifice aligned with the oil flow channel, and the cylindrical outer structure, the first and second ends, and the internal support structure are continuously and unitarily formed.

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.

Abstract: 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.
