## Summary

Nima Shamsaei, a professor at Auburn University and Director of the National Center for Additive Manufacturing Excellence (NCAME), discusses the fatigue and fracture behavior of additive manufacturing (AM) materials. He explains that unlike traditional manufacturing, AM failure mechanisms are often anomaly-related, making prediction-based qualification critical for adoption. Shamsaei details a joint project with NASA and the US government, called RAMP, which supports small enterprises in qualifying parts for aerospace use by characterizing over 50 materials. He argues that while AM is expensive, redesigning parts to leverage complex geometries unlocks its full potential, whereas simple supply-chain replacements face higher qualification barriers due to fatigue risks.
