Additively manufactured (AM) components often exhibit significant flaws and discontinuities without out a clear understanding of how they might degrade the performance of a part in service. This uncertainty is unacceptable for the design and manufacturing of most aerospace components. This paper provides a background into Sandia’s research efforts and explore AM production-ready processes and identifies disqualifying flaws in AM components by using advanced diagnostic methods. Examples of computed tomography and ultrasonic spectroscopy to assess inherent flaws within components will be discussed. A combination of modeling, material property evaluation, microstructural characterization, and non-destructive techniques will be presented and help provide scientifically-based basis for determining inspection criteria and part qualification.
