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 for forming a part layer by layer using an additive manufacturing apparatus. The additive manufacturing apparatus includes a resin support, a stage, a measuring system, and an actuator configured to change the relative position of the stage and the resin support. The method includes the steps of: performing an additive manufacturing cycle including the following steps: depositing an uncured layer of resin; moving the stage to a target location; curing the uncured layer of resin; and moving the stage away from the target location; repeating the additive manufacturing cycle; performing a measuring process wherein the measuring process includes the following steps: using the measuring system to take a measurement indicative of an actual position of a structure; comparing the actual position of the structure to an expected position of the structure to determine an error; and using the error to modify the target location.

Abstract: An additive manufacturing apparatus is disclosed. The apparatus includes a build surface, at least a portion of which is transparent. The apparatus includes a first material depositor operable to deposit a curable resin to form a deposited resin layer on the build surface. A first sensing device is configured to measure the thickness of the deposited resin layer; and wherein the at least one sensing device is configured to generate a signal indicative of the thickness of the deposited resin layer. The first sensing device can be connected to a computer such that the additive manufacturing apparatus is configured to control the thickness of the deposited resin layer. The thickness of the deposited resin layer can be controlled such that it varies from side to side, i.e. across the width of the deposited resin layer in the transverse direction along the x-axis. The thickness can also be controlled such that it varies with time, i.e., in the machine direction along the y-axis.

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: A method is provided for repairing defects in a ceramic core adapted for use in a casting process. The ceramic core is formed from a slurry comprising at least one refractory powder material suspended in a liquid vehicle. The method includes forming a repair mixture comprising a liquid diluent and the at least one refractory powder material suspended in the liquid vehicle of the slurry. The repair mixture is applied to a region of the ceramic core that includes at least one defect and then the ceramic core is fired to burn off the liquid vehicle in the repair mixture and form a ceramic composition that closes the defect.

Abstract: A method is provided for casting a component. Accordingly, data indicative of at least one location of a unitary core-shell mold which is susceptible to a stress concentration is received. An additive manufacturing process is employed to form the unitary core-shell mold defining a casting cavity. The unitary core-shell mold includes a shell wall defining an outer component shape and a core wall positioned inward of the shell wall. The core wall defines an inner component shape. The core wall and/or the shell wall defines at least one reinforcement recess adjacent to the at least one location which is susceptible to the stress concentration. Following the forming of the unitary core-shell mold, at least one support member is positioned within the reinforcement recess in contact with the at least one location. With the support member in place, the component is cast within the casting cavity.
