Its not the forging, its the tempering. Until we have large scale/atomic precision printers (I wouldn't hold my breath for that to arrive) you're printers won't be able to create the mono-crystalline alloys required for modern Jet engines.
Huh, that makes me think: a metallic 3-d printer is conceptually a forge turned inside out.
