AI in practice: 2 real uses of AI described

What this episode covers

Paul Gradl, Principal Engineer at NASA, discusses the expansion of additive manufacturing materials, highlighting high-performance alloys like GR COP and GRX 810 developed for extreme environments and now used in semiconductors and energy. He explains how AI and modeling are accelerating alloy development, while NASA shares public data to help the industry overcome qualification challenges. Gradl also details the scaling of large-scale parts via Directed Energy Deposition (DED), the role of additive in space infrastructure including lunar regolith printing, and a recent test stand failure that underscored the importance of understanding process sensitivities like build interruptions.

AI in practice

Engineering & simulation

NASA uses machine learning to analyze large datasets of material test results to predict how slight changes in chemistry or parameters will affect material properties, accelerating the understanding and potential qualification of new alloys.

“I can use some machine learning to help analyze some that data and predict, you know, further, okay, if I were to change this chemistry slightly or these parameters slightly, how is that going to change some of the properties?”

Engineering & simulationsimulations and modeling techniquesdeveloped within months vs. years

NASA uses thermodynamic simulations and custom software to model potential material properties and limitations during the development of new alloys like GRX 810, significantly accelerating the development timeline from years to months.

“our initial material development, like GRXA 10, we use a lot of simulations and modeling techniques, you know, both off the shell software and some custom software that allows us to, you know, model it thermodynamically, understand potential material properties with it, some of the limitations of it. So certainly that side of it has accelerated.”

    Why Your Toughest Parts Still Use 50-Year-Old Materials w/ Fazal Mahmood

    Fazal Mahmood, co-founder and CEO of Phase Shift Technologies, explains how AI is accelerating the discovery of new metal alloys to replace 50-year-old materials in industries like oil and gas, aerospace, and defense. He details the critical gap between designing a material and qualifying it for regulated markets, noting that legacy producers often lack the incentive to innovate outside their core franchises. Mahmood highlights three key drivers for this shift: the maturation of additive manufacturing, the performance limits of existing materials in technologies like nuclear fusion, and supply chain disruptions in critical raw materials like tungsten. He illustrates these points with a specific example of a new printable tungsten carbide alloy designed for laser powder bed fusion to solve wear resistance issues in complex flow components.

    The Digital Warehouse: A Look Inside Additive Manufacturing w/ Melanie Lang

    Melanie Lang, Co-Founder and CEO of FormAlloy, discusses the evolution of additive manufacturing from prototyping to production, focusing on Directed Energy Deposition (DED) technology. She explains how DED uses laser energy and metal powder to build or repair parts layer-by-layer, enabling multimaterial solutions and large-scale builds without support structures. Lang highlights aerospace applications like rocket nozzles and heat exchangers, where DED combines copper alloys for thermal properties with nickel superalloys for strength. She also addresses the industry's shift toward viewing manufacturing as a 'digital warehouse,' where digital files replace physical inventory, though she notes that trust and certification standards are still evolving.
