Niall O'Dowd (University of California San Diego)25/11/2019, 17:50Recent Research TopicsOral PresentationMetal parts created by additive manufacturing are often difficult to dimensionally characterize due to the complex surface structures created by welding phenomena present in state-of the art printing machines. The most holistic techniques involve measuring the surface of each sintered layer of powder, however, this is complicated to perform in a non-contact, non-destructive, and in-situ...Go to contribution page

Jonas Eriksson (Siemens Industrial Turbomachinery)26/11/2019, 16:00Recent Research TopicsOral PresentationWhen Siemens in Finspong introduced selective laser melting (SLM) on a broader scale, it became soon clear that the machine performance did not reach the high expectations concerning process stability, repeatability and transferability between several machines of the same type. That is why Siemens with the involvement of machine learning and big data specialists developed the โSiemens AM...Go to contribution page

Priyanshu Bajaj (Max Planck Institute for Iron Research)26/11/2019, 17:00Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationIn additive manufacturing (AM), parts are built from layer by layer fusion of raw material (eg. wire, powder etc.). Such layer by layer application of heat results in a time-temperature profile which is fundamentally different from any of the contemporary heat treatments. Previous works have established that this unique thermal profile can be exploited for microstructural modifications (eg....Go to contribution page
