Through additive manufacturing (AM) the ability to locally control the heat input into a material in a site-specific manner has been largely demonstrated in both laser and electron beam processes. Through this has given rise to the ability to locally control texture in some alloys. While the ability to manipulate the heat source in electron beam melting between a point, line, and area heat source is easily achievable, the manner in which to extend this to complex non-prismatic geometries is not trivial due to the complex thermal boundary conditions encountered in the EBM process. To be discussed is the role of modeling in conjunction with advanced scan strategies designed to be geometry sensitive. Through advanced beam scan strategies comes the ability to control texture across complex geometries and also as a means to mitigate material defects and influence liquid-solid phase transformations within the materials being fabricated.
