METHOD FOR FORMING COMPONENTS USING ADDITIVE MANUFACTURING AND RE-MELT

摘要

A method of manufacturing a component (W;84) includes additively manufacturing a crucible (100); directionally solidifying a metal material within the crucible (100); and removing the crucible (100) to reveal the component (W;84). A component (W;84) for a gas turbine engine (20) includes a directionally solidified metal material component (W;84), the directionally solidified metal material component (W;84) having been additively manufactured of a metal material concurrently with a core (102), the metal material having been remelted and directionally solidified.
