Abstract: A method for capturing trapped powder from a part during an additive manufacturing process, the method comprising defining parameters for a part, the part defining an interior passageway defined by interior sidewalls, defining parameters for a powder removal cap, the powder removal cap comprising a body portion and a thin radial membrane connected to the interior sidewalls of the part, simultaneously creating the part and the powder removal cap via additive manufacturing, wherein the powder removal cap is created within the interior passageway and, upon completion of the creation of the part and the powder removal cap, the powder removal cap traps excess powder within the interior passageway, removing the powder removal cap from the interior passageway by breaking the radial membrane from the interior sidewalls to permit access to the interior passageway, and capturing the excess powder within the interior passageway.

Abstract: A method and system for composite molding, and the method includes additively manufacturing a mold shell that includes a part forming cavity. The method includes filling at least a portion of the mold shell with a strengthening agent. The method includes hardening the strengthening agent to form a mold, and laying-up a composite material on the part forming cavity. The method includes curing the mold to form a composite part.

Abstract: Presented are hybrid fixture assemblies with integrated additive manufactured features, methods for making/using such fixtures, and manufacturing systems equipped with such fixtures. A manufacturing fixture assembly includes a fixture support frame formed, at least in part, from a first material, and a fixture support shell formed, at least in part, from a second material distinct from the first material. The support frame, which seats on/mounts to a work surface, includes a skeletal substructure with multiple male connectors projecting therefrom. The skeletal substructure contains multiple first frame walls that are removably intermeshed with multiple second frame walls in a collapsible format. The support shell includes a support surface that holds a workpiece, an interface surface that abuts the skeletal substructure, and multiple female connectors that project from the interface surface. Each female connector removably receives therein a respective male connector to thereby detachably mount the support shell to the support frame.

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: 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: Systems and methods are provided for building a product by additive manufacturing and creating hollow volumes without including build supports in the hollow volume for the layers above the hollow volume. An additive manufacturing cell includes a material handling device, a printer a material delivery system and an energy source to feed the sheets, print on the sheets, apply a powder on the printed sheets, build a hollow volume into the sheets and consolidate the sheets into a product with a contiguous structure.

Abstract: Low waste methods for three-dimensional printing techniques are provided. A method includes performing a preceding additive infusion process including: solubilizing an additive into a medium in a supercritical fluid state; contacting a preceding material with the medium to infuse a portion of the additive into the preceding material to form a preceding additive-infused material; and separating remaining additive from the medium. Further, the method includes performing at least one succeeding additive infusion process including: solubilizing the remaining additive and, optionally, additional additive, into the medium in a supercritical fluid state; and contacting a succeeding material with the medium to infuse at least a portion of the remaining and additional additive into the succeeding material to form a succeeding additive-infused material, wherein the medium from the preceding additive infusion process is reused in the at least one succeeding additive infusion process.
