Abstract
A method is provided for manufacturing a component. This method includes additively manufacturing a crucible for casting of the component. A metal material is directionally solidified within the crucible to form a metal single crystal material. A sacrificial core is removed to reveal a metal single crystal component with internal passageways. A component is provided for a gas turbine engine that includes a metal single crystal material component with internal passageways. The metal single crystal material component was additively manufactured of a metal material concurrently with a core that forms the internal passageways. The metal material was also remelted and directionally solidified.

A method of manufacturing a component, the method comprising:
- additively manufacturing the component of a metal material;
- additively manufacturing a core at least partially within the component;
- at least partially encasing the additively manufactured component and the additively manufactured core within a shell;
- melting the additively manufactured component;
- directionally solidifying the metal material of the additively manufactured component to form a metal single crystal material component;
- and
- removing the shell and the additively manufactured core to reveal the metal single crystal material component with internal passageways.
