Part qualification and reliability are two important challenges for the evolving Additive Manufacturing industry today. It has become extremely hard to perform time-consuming experiments to address the above-mentioned challenges and therefore, automated qualification and reliability predictions using validated scientific software has become a necessity rather than using these tools as an accessory. 3DSIM has already developed thermal and structural tools to predict process related thermal and distortion evolutions. A new location specific predictive microstructural tool is being developed which can predict grain size and orientation evolutions in the part as a function of cooling rate and thermal gradient. A computational case study on above-mentioned evolutions using Ti6Al4V alloy processed with scan pattern variations in selective laser and electron beam melting will be presented. These evolutions could be further tied to anisotropic property predictions for which 3DSIM already possesses predictive capabilities.
