GE Aerospace/Additive's perspective on the industrialisation of Additive Manufacturing: certification of aeronautical parts (stability, repeatability, production scale-up) and latest developments in laser productivity and PointMelt in EBM

José Greses - Emea Sales Leader - GE Additive (MAQUINSER)

The talk will present GE Aerospace's industrial developments in Additive Manufacturing for its aeronautical turbines over the last decade, as well as the developments based on GE Additive's AM technologies that will be applied to the next generation of turbines. Of all these developments, we will focus on explaining how to increase productivity, reducing cost per part, within the same platform by increasing laser power in combination with 3D optics and the new Point Melt fusion strategy for Electron Beam Melting (EBM) technology. The "Point Melt" (GE Additive patent) in EBM, for the first time in additive metal manufacturing, makes it possible produce without the need of supports or a baseplate in any orientation, achieving isotropic mechanical properties and constant roughnesses. All these advantages allow a very significant cost reduction per part by dispensing with manual or very complicated post-processing, as well as a control of the microstructure of the molten material in a totally new way, which opens up new possibilities with metals that are difficult to weld (such as MAR247 nickel base alloys for high turbine temperatures, or high hardness steels (70HRC) for high wear applications)
