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: A high pressure die casting (HPDC) system for casting ultra-large single-piece castings for vehicles. The HPDC system includes a clear feeding path from at least one ingate to a predetermined thicker section of a mold cavity, a last to solidify ingate having an equivalent or larger feeding modulus than the highest feeding modulus of the other ingates, and thermal management elements. The clear feeding path, last to solidify ingate, and thermal management elements ensure sufficient supplemental molten metal flow to the thicker portion of the mold cavity to accommodate for shrinkage of the thicker portion of an ultra large casting during the casting and solidification process.

Abstract: A method of joining two ferrous alloy component parts. The method includes hot metal casting a portion of a first ferrous alloy component part onto a first joining surface of a low carbon intermediate element; friction fitting a joining surface of a second ferrous alloy component part against a second joining surface of the low carbon intermediate element; and fusion welding with a concentrated energy source the intermediate element to the second ferrous alloy component part. The hot metal casting includes flowing a molten ferrous alloy onto the textured first joining surface, wherein the molten ally encompasses tabs extending from the first joining surface and filling apertures defined in the intermediate element. Then cooling the molten ferrous alloy such that a metallurgical and mechanical bond is formed between the portion of the first ferrous alloy component part and the first joining surface of the low carbon intermediate element.

Abstract: Systems and methods are provided for controlling additive manufacturing material deposition using a magnetic field. A system may include a build surface; a material depositor through which a magnetically responsive material is deposited on the build surface; an energy source; and a magnet set. The magnet set applies the magnetic field to the build surface and/or to the material depositor. The magnetic field is configured to attract the magnetically responsive material while the energy source melts the magnetically responsive material.
