Additive manufacturing of parts fabricated from structural materials occurs on a much finer scale than many other popular manufacturing techniques. The ability to make processing decisions at this scale offers new and promising paths for microstructure control and design. A major component of microstructure in structural materials is crystallographic texture. Parts produced by laser powder bed fusion additive manufacturing have been observed to develop a range of textures during fabrication. The strength of these textures is variable and dependent on a variety of processing factors. The driving physics of these textures is well understood and can be used to inform the processing decisions made during fabrication. We present a study of the modification of laser powder-bed fusion processing parameter to tune crystallographic texture within Inconel 718 parts. Experimental testing is undertaken to understand the mechanical response of the texture control and its impact on overall part performance.
