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.

Abstract: An anti-submarining seat cushion for a vehicle includes a main body constructed of an anisotropic material. The anisotropic material includes a primary material including a primary stiffness and a plurality of inserts that are dispersed throughout the primary material. The plurality of inserts exert an axial compressive force in response to the main body of the anti-submarining seat cushion experiencing a submarining load, where the axial compressive force is exerted in a direction that opposes the submarining load to increase an overall stiffness of the main body in a direction that aligns with the submarining load.

Abstract: A thermal management device for dissipating heat from an electrical component includes a volume of working fluid configured to change from a liquid state to a vapor state in response to being heated by the electrical component. The thermal management device also includes a working fluid chamber configured to move the working fluid. The working fluid chamber includes an impermeable outer portion and a porous inner portion integrally formed with and connected to the impermeable outer portion. The inner portion is configured to move the working fluid when in the liquid state toward the electrical component. The impermeable outer portion is made of a first material and the porous inner portion is made of a second material. The first material is different from the second material.

Abstract: An additive manufacturing method comprises: positioning a sheet of composite material; curing a predetermined portion of the sheet; cutting the sheet about the perimeter of the predetermined portion to create a preceding processed sheet; adding a successive sheet of composite material atop and in contact with the preceding processed sheet; curing a predetermined portion of the successive sheet such that the predetermined portions of the successive sheet and the preceding processed sheet are bonded together; and cutting the successive sheet about the perimeter of its predetermined portion to create a subsequent processed sheet. The steps of adding, curing and cutting a successive sheet may be repeated for a plurality of cycles to produce a three-dimensional composite product.

Abstract: A ceramic foam filter system includes a filter body having multiple tortuous path channels through the filter body to filter a molten liquid. A filter holder configuration defining a canister in a runner passage receives the filter body. An upstream end of the filter body receives the molten liquid having multiple inclusions. A predominant portion of the inclusions are larger than the multiple tortuous path channels and are trapped against the upstream end of the filter body. The multiple tortuous path channels are sized to trap a predominant portion of multiple oxides within the molten liquid as trapped oxides within the filter body. A filtered molten material having the multiple inclusions and the multiple oxides removed is directed from the multiple tortuous path channels as a discharge flow to exit at a downstream end of the filter body.

Abstract: A vehicle seat cushion for a vehicle that includes a seat cushion support structure, and a lattice-structured support that is supported by the seat cushion support structure. The lattice-structured support provides a first resistive force in response to a vertically applied force that is less than a second resistive force in response to a force aligned with an H-point travel path of the vehicle occupant during a vehicle impact event.
