Ahh! My fervent wish is to be able to 3D print brass, aluminum,
or steel... But alas, that won't be for a while.
What I see that says it is 3D printed brass, or aluminum, is in
actuality a slurry of brass flakes, or aluminum flakes, and some
organic (plastic) meltable binder. The brass or aluminum comes
to the surface in a way that makes it appear to be brass or aluminum,
but the strength is all plastic.
I read an article of a M1911A2 being entirely printed in steel, but
I never heard how they did that, only that they would happily sell
you one of their printed guns for $30K.... To help fund research,
I suppose something like a mig welder controlled by a 3D mechanism
would do something... but it would be brutally inefficient.

I've no doubt you are correct.
When I stated "parts could be manufactured in brass or aluminium", I was thinking of
3D printing them. It would have helped if I had been more precise.
Sorry for the confusion.
