  • Publication number: 20220355369
    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.
