Abstract
A method of manufacturing a component includes additively manufacturing a crucible; directionally solidifying a metal material within the crucible; and removing the crucible to reveal the component. A component for a gas turbine engine includes a directionally solidified metal material component, the directionally solidified metal material component having been additively manufactured of a metal material concurrently with a core, the metal material having been remelted and directionally solidified.
Claims12
A method of manufacturing a component, comprising:
- additively manufacturing the component with a metal material;
- additively manufacturing a core at least partially within the component;
- at least partially encasing the component and the core within a shell;
- melting the additively manufactured component;
- solidifying the metal material of the additively manufactured component to form a directionally solidified microstructure within the component;
- and
- removing the shell and the core to reveal the component.
