Additive manufacturing (AM) is quickly maturing as a mainstream production method. AM will enable the engineering of highly complex, design-optimized components, where the production can be driven by the design, and not the other way around. Applications span defense, aerospace, automotive, marine, oil & gas, and manufacturing industries, for example. However, in order to fully exploit the benefits and possibilities of AM, the processes and challenges associated with the new opportunities need to be fully understood, and the reliability of the components included as part of the design process. This work presents the groundbreaking opportunity for a methodology to rapidly qualify AM parts, enabling their widespread industrial use.

The technology that is being developed in this STTR is a data-driven machine learning algorithm with key capabilities that will enable a user to reduce the time, cost and resources required to characterize additive manufacturing (AM) materials and AM processes. This technology will be productized as an ICME software tool and will be commercialized by Senvol. The overall intention is for the algorithm to be AM material, machine and process agonistic and for the algorithm to learn from previous data sets and apply those learnings to new data sets. The proposed ICME tool can be used to assist the Navy in developing statistically substantiated material properties (in lieu of relying on conventional material characterization methods that could be used to develop design allowables). In addition to uses within the Navy, it is expected that the probabilistic framework will be used by the AM industry at large, and in particular by aerospace and defense contractors and the Navys supply chain at large.
