Either there are errors in this transcript, or Mr. Lammas needs to get his story straight. Additive is a welding process that only prints materials you couldn't weld? Huh? I hope his engineers back in the home office kicked him in the teeth.

Additive is basically a welding process, so you can only print materials that you couldn't weld. Some of our high-temperature materials you can't weld.

I think the parts JM was talking about were for stationary gas turbines, something like these:

Not sure how many of the aircraft engine nozzle tips are in use and in flight in the LEAP engine--in any case, GE may be using equipment like this to inspect them:

I like Sigma's trademark Quality Beyond Inspection™ because it processes real-time data to provide "actionable results" (I think that's the term MC uses) so one doesn't have to wait until the whole thing has been built up to discover it has to be tossed. Also, the data stream produced by the PrintRite3D® SENSORPAK™ has info that one can't obtain by looking at the part with a scanner.
