Abstract: The present disclosure relates to a method of forming a cast component and a method of forming a casting mold. The method is performed by connecting at least one wax gate component to a ceramic core-shell mold. The ceramic core-shell mold includes at least a filter, first core portion, a first shell portion, and at least one first cavity between the core portion and the first shell portion. The core-shell mold may manufactured using an additive manufacturing process and may include an integrated ceramic filter. At least a portion of the ceramic core-shell mold and the wax gate component is coated with a second ceramic material. The wax gate component is then removed to form a second cavity in fluid communication with the first cavity.

Abstract: A method of forming a cast component and a method of forming a casting mold is generally provided. The method is performed by plugging or covering an opening in a ceramic core-shell mold. The ceramic core-shell mold includes at least a first core portion, a first shell portion, and at least one first cavity between the core portion and the first shell portion. The core-shell mold may be manufactured using an additive manufacturing process. At least a portion of the ceramic core-shell mold and the plug or cover is coated with a second ceramic material.
