Magbeach2, I see your point about Boeing. It's possible.

But I'm leaning Airbus on account of Aubert & Duval having been purhased by a consortium led by Airbus.

Yes, A&D do sell into Boeing (and other manufacturers) parts market. But my hunch is Airbus would want to secure their own supply of AM powders. Add to this that Pryogenesis is scouting European AM powder plant location... I am guessing Airbus.
