August 27, 2018, © Leeham News: For all its potential, additive manufacturing faces significant hurdles before it can deliver on advocates’ assertions that the technology will revolutionize the aerospace industry.

United Technologies is counting on additive manufacturing, often called 3D printing, to help it develop and produce new components faster, better and cheaper. Paula Hay is leading the expansion of additive manufacturing at United Technologies Aerospace Systems (UTAS). In part two to last week’s interview with Hay, LNC talks to her about what problems have to be solved for additive manufacturing (AM) to make good on its potential.

Summary

  • Need more consistent materials and equipment.
  • OEMs and regulators have to develop AM standards.
  • Design culture has to evolve to reflect AM capabilities.

It has been there since Kitty Hawk: Balancing the hunger to push technological boundaries with the desire to stay safe.

The Wright Flyer only flew after years of painstakingly testing airframes and engines. That tension between being bold and being safe is evident today in commercial aerospace’s adoption of additive manufacturing.

Just about every major player in the aerospace industry is exploring additive manufacturing, or 3D printing. Most of the integration has been at the margins. The technology is still young enough that there is no clear leader in its application to aerospace. Everyone is trying to find how to get the most from it.

Summary

  • Begin with mechanical, not structural systems.
  • Big parts reductions.
  • Big reduction in lead time.
