At my work we use 3D printing to make 3D wire flexures out of titanium powder. (wire flexure are metal elastic "hinges" basically). 3D printed metals nowadays have 98% of the strength of the normal material, so there's only the limitation of delamination (cracking in between the 3D printed layers). Using laser sintering this will be solved soon I think, and takes another ~10 years to enter your living room.
But as I said, the possibilities, even today, are underestimated. Printing a durable lower receiver isn't far off.
