Abstract: The present disclosure generally relates to integrated core-shell investment casting molds that provide a filament structure corresponding to a cooling hole pattern in the surface of the turbine blade, stator vane, or shroud. The disclosure also relates to the forming of a ceramic coating on at least a portion of the shell of the core-shell casting mold.

Abstract: A method of casting a truss structure having spaced face sheets connected by columnar structures, including forming a three-dimensional pattern (3D pattern) in the shape of the truss structure with the spaced face sheets and columnar structures, forming a mold core of the 3D pattern by surrounding the pattern with a liquid and letting the liquid harden about the 3D pattern, removing the 3D pattern from the mold core, filling the mold core with a liquid alloy to cast and directionally solidify the truss structure.

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 first core portion, a first shell portion, and a second shell portion, wherein the first shell portion is adapted to interface with at least the second shell portion to form at least one first cavity between the core portion and the first and second shell portions. The core-shell mold may be inspected and assembled prior to connection of the wax gate component. 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: The present disclosure generally relates to partial integrated core-shell investment casting molds that can be assembled into complete molds. Each section of the partial mold may contain both a portion of a core and portion of a shell. Each section can then be assembled into a mold for casting of a metal part. The partial integrated core-shell investment casting molds and the complete molds may be provided with filament structures corresponding to cooling hole patterns on the surface of the turbine blade or the stator vane, which provides a leaching pathway for the core portion after metal casting. The invention also relates to core filaments that can be used to supplement the leaching pathway, for example in a core tip portion of the mold.

Abstract: A method for fabricating a ceramic mold is provided. The method includes the steps of contacting a cured portion of a workpiece with a liquid ceramic photopolymer, irradiating a portion of the liquid ceramic photopolymer adjacent to the cured portion through a window contacting the liquid ceramic photopolymer, removing the workpiece from the uncured liquid ceramic photopolymer, and repeating the steps until a ceramic mold is formed. The ceramic mold includes a first opening for creating a cast article and a second opening for receiving a support member.

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.
