In-process monitoring has given us fantastic scientific insight into the physics of metal additive manufacturing processes, providing new understanding of melt pool dynamics, plume behaviour, and defect formation mechanisms. However, translating this insight into industrial-scale quality assurance remains a challenge, despite the availability of sensors and software from machine manufacturers. This talk will explore the scientific progress achieved through in-process monitoring, including the identification of defect-causing phenomena and their detection to generate 3D maps of porosity and critical defects. It will also discuss emerging approaches to digital quality assurance, including the integration of machine learning and non-destructive evaluation methodologies, and how they can accelerate the qualification and adoption of metal additive manufacturing technology.
