I'm referring to the use of 3d printing in mass production.

Mass production of modern jet fighters is dozens of units; not millions. 3d printing has been cheaper than tooling for various parts for decades.

I'm not necessarily knocking the Chinese; they are masters at traditional tooling and manufacturing in ways we simply don't have the talent base to replicate. But for the same reasons, we are decades ahead in additive manufacturing and Uncle Sam only knows how far ahead in aerospace technology.

I'm more knocking the headline that 3d printing is new or advanced in the field of aero defense.
