A system (5) and method (800) for unit cell casting of titanium or titanium-alloys is disclosed herein. The system (5) comprises an external chamber (45), a crucible (10) positioned within the external chamber (45), an induction coil (15) positioned around the crucible, an internal chamber (40) positioned within the external chamber (45), and a mold (30) positioned within the internal chamber (40). The external chamber (45) is evacuated and a pressurized gas is injected into the evacuated external chamber (45) to create a pressurized external chamber (45). An ingot (20) is melted within the crucible utilizing induction heating generated by the induction coil (15). The internal chamber (40) is evacuated to create an evacuated internal chamber (40). The titanium alloy material of the ingot (20) is completely transferred into the mold (30) from the crucible (10) using a pressure differential created between the external chamber (45) and the internal chamber (40).

A modular spruing system apparatus contains a base section, a main sprue cone, a center rod, a plurality of trunk sections, a plurality of arm sections, and an end cap. The main sprue cone is mounted onto the base section. The center rod centrally traverses through the base section and the main sprue cone so that the user can design a spruing tree of desired height. A center rod receiving hole of each of the plurality of trunk sections allows the center rod to traverse through the plurality of trunk sections when removably attached to each other. Next, the plurality of arm sections is attached to the plurality of branch sections. The plurality of arm sections can be fixed or removably attached to the plurality of branch sections. When the desired height is reached, the plurality of trunk sections is fastened together with the end cap.

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.
