Additive manufacturing (AM) is a rapidly emerging and continuously evolving technology. It has already significantly impacted the manufacturing community enabling low volume production of commodity parts, where and when they are needed. However, the high cost and time associated with AM process qualification and component certification have significantly impeded the widespread use of AM metallic parts used in critical applications. In this presentation, the need to shift from the conventional statistically substantiated means of qualification to a probabilistic means utilizing both machine learning and Integrated Computational Materials Engineering (ICME) will be explored. Further, attention will be given to the importance of surface condition and post AM fabrication processing on component fatigue life.
