IS12 - Process-structure-Properties Relationship in Laser-based Powder Bed Fusion of Metals

Organized by: M. Carraturo, S. Morganti, A. Reali and F. Auricchio (University of Pavia)
Additive Manufacturing (AM) technologies are undergoing exponential growth in many engineering fields, from aerospace to biomedical applications, from fashion to the food industry. In particular, Laser-based Powder Bed Fusion of Metals (PBF-LB/M) is the technology which is nowadays leading the AM market for engineering applications due to its capability to produce close-to-freeform components with structural and mechanical properties close or even superior to the ones obtained using traditional manufacturing processes. In fact, thanks to the recent advancements in PBF-LB/M technology, manufacturing constraints are dramatically reduced and the designer can finally focus on the intended application of the part rather than on its manufacturability. As a direct consequence of PBF-LB/M widespread diffusion, there is an increasing necessity of a deeper understanding of the complex process-structure-property relationships to optimize the manufacturing parameters as well as to generate the optimal design of the 3D printed part. The present Symposium aims at presenting and discussing the most recent results in the exciting and challenging field of PBF-LB/M technology development. The Symposium addresses, but is not limited to, the following topics: • Process modelling and validation • Material modelling • Metrology and sensing techniques • Uncertainty quantification • Ontologies for PBF-LB/M
