| Abstract Scope |
Process monitoring is a significant area of ongoing research in the laser powder bed fusion (LPBF) community because of its potential to accelerate part certification and qualification. A variety of different monitoring modalities have been applied to LPBF including approaches based on thermal emission, plasma emission, acoustic emission, optical and infrared imaging, and others. These disparate monitoring approaches provide different and often complimentary information about process stability. This talk will give an overview of how multiple monitoring approaches can be used in a complimentary fashion to identify both process stability and defect formation events. This is accomplished by selecting monitoring modalities that probe orthogonal aspects of the physical process. The primary focus will be on optical and acoustic emission monitoring in concert with high speed X-ray imaging, but other modalities will also be discussed.
