Short Course: NDE for Additive Manufacturing
Monday, 24 October 2022, 09:00 – 10:30 h, Registration fee: 150 Euro
parallel to Short Course: The World of NDE 4.0: Let the Journey Begin
Additive Manufacturing is a key manufacturing technology in Industry 4.0, with its unique digital manufacturing capabilities for near-net shape manufacturing of parts on demand, in short lead times and in distributed manufacturing facilities reducing costs. This enhances not only supply chains but also allows unique geometries to be manufactured for enhanced performance providing benefits in low mass, enhanced mechanical properties tuned specifically to a particular application, enhanced thermal properties with unique cooling channels and lattice structures, amongst others.
In this workshop, the current growth and application areas of metal additive manufacturing (AM) technologies are discussed in the context of NDE. As the most widely used AM process in industry, laser powder bed fusion, is discussed in depth in order to better understand the unique material conditions leading to unique NDE needs and requirements. The workshop follows the book Fundamentals of Laser Powder Bed Fusion of Metals  and spends particular attention to AM-specific defects, porosity, residual stresses, surface conditions and other unique characteristics, the causes and mechanisms behind these and how these can be detected. NDE is discussed in relation to the challenges including latest trends and industry adoption of NDE for this area with its challenges that remain to be solved in near future.
