Borescope bosses for A320neo Geared Turbofan TM engine
Benefit: Improved Performance
Main Forming Process: Additive Manufacturing
End Use Sector: Aerospace
Material: Nickel


The bosses are made by selective laser melting (SLM) on an EOS machine. They form part of MTU’s low-pressure turbine case and allow the blading to be inspected at specified intervals for wear and damage using a borescope.


  • Series production of up to 2,000 parts per year.
  • Lower development production leadtimes and lower production costs
  • Suitable for producing parts in materials that are difficult to machine, as, for example, nickel alloys
  • For complex components that are extremely difficult, if not impossible to manufacture using conventional methods
  • Tool-free manufacturing and less material consumption
