Not CNC, because you can't mechanically mill very thin sheets of metal.  it doesn't have enough strength to provide the reactive force against the tool.  But now that you mention it, we can now use additive manufacturing (i.e., 3D printing) these days for many of the things that we used to need chem-milling for.

Can 3D-printing produce an airtight surface?
Well, it is like this: The truth doesn't need insults. Insults are the refuge of a darkened mind, a mind that refuses to open and see. Foul language can't outcompete knowledge. And knowledge is the result of education. Education is the result of the wish to know more, not less.

If by "3D printing" you mean all additive manufacturing, then yes absolutely.

For example, selective laser melting can be used with any metallurgy compatible with welding. SpaceX has manufactured rocket engines with this method.
