Advanced EHLA3D Process Development

How close is EHLA3D to industrial production of turbomachinery parts made of IN738?

Challenge and Motivation

  • Growing demand for high-performance, hard-to-weld Ni super alloys in turbomachinery applications.
  • Current EHLA3D process development for IN738 indicates promising results which can be utilized for transfer to an industrial application.


  • Demonstration and validation of an industrial use case as a result of advanced process development.
  • Mapping of the entire manufacturing process chain (AM, HT and finishing).
  • Reduced application barrier for EHLA3D technology.
