Abstract
An additive manufacturing system utilizing an epitaxy process, and method of manufacture, utilizes a heating source and a cooling source to control thermal gradients and a solidification rate of each slice of a workpiece manufactured from a seed having a directional grain microstructure. An energy gun is utilized to melt selected regions of each successive layer of a plurality layers of a powder in a powder bed to successively form each solidified slice of the workpiece.
