Unit Cell Titanium Casting

A system method for unit cell casting of titanium or titanium-alloys, the system comprising:

• an external chamber;
• a ceramic crucible positioned within the external chamber;
• an induction coil positioned around a bottom section of the ceramic crucible;
• an internal chamber positioned within the external chamber;
• and
• a mold positioned within the internal chamber;
• wherein the mold is preheated prior to placement in the internal chamber;
• wherein the external chamber is evacuated to create an evacuated external chamber wherein the ceramic crucible contains a titanium alloy ingot positioned therein;
• wherein a pressurized gas is injected into the evacuated external chamber to create a pressurized external chamber;
• wherein the titanium alloy ingot is melted within the ceramic crucible utilizing induction heating generated by the induction coil positioned around the ceramic crucible;
• wherein the internal chamber is evacuated to create an evacuated internal chamber;
• wherein the titanium alloy material is completely transferred into the mold from the crucible using a pressure differential created between the external chamber and the internal chamber.
