Abstract: 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 be 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: An apparatus for casting a part that includes a first housing, a second housing, a handling system and a cooling apparatus. The first housing defines a first chamber. The first chamber is configured to receive a melt heater and a mold heater. The second housing is configured to move between a first position and a second position such that when the second housing is in the first position, the first housing is open such that a mold can be inserted therein and when the second housing is in the second position, the second housing and the first housing define a second chamber. The cooling apparatus is configured to be positioned within the second chamber.

Abstract: A method for producing a cast component is provided. The method includes attaching a ceramic mold to a seed crystal body, the ceramic mold including a cavity defining the shape of the cast component and a seed crystal body interface having a complementary shape to the seed crystal body such that the seed crystal body may be capable of supporting the ceramic mold in a casting oven. The method also includes pouring a liquid metal into the mold such that the crystal seed portion contributes to controlled crystallization of the cast component.

Abstract: Methods for creating a cast component, along with the resulting cast components, are provided. The method may provide for a controlled grain structure in the resulting cast component. The methods may include heating at least a first portion mold under controlled conditions, such as when the first portion of the mold is buried in a ceramic powder.

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.

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.
