ASTM International, NASA to host in-situ monitoring for additive manufacturing

The ASTM International Additive Manufacturing Center of Excellence (AM CoE) is holding its second specialty workshop series on in-situ technology readiness for applications in AM qualification and certification on Jan. 26, 2022, in Huntsville, Ala. The workshop is hosted in collaboration with the U.S. National Aeronautics and Space Administration (NASA) Marshall Space Flight Center (MSFC).

In-situ monitoring technologies for additive manufacturing may be used as a means of controlling part quality, reducing ex-situ inspection requirements, and providing insights on elements of the AM value chain, including feedstock and design. Ultimately, in-situ technologies could provide a solution to quality assessment of components with complex geometries that are hard to inspect via traditional ex-situ inspection techniques.

Government, industry and academic participants will meet to address relevant topics, including:

•   Approaches to qualification using in-situ methods as a quality assurance tool in critical applications;
•   Integrations of in-situ monitoring systems in production for real-time monitoring and closed-loop control; and
•   Correlation of in-situ monitoring data to material defect states and process escapes, computational models, and traditional inspection techniques.
