3dprinting out of almost any material is used regularly in that industry.


Very, very complex steel, stainless steel, or even titanium components with insane geometry can be made, and even machined internally using laser deposition 3d welders. Some very unique, custom alloys can be mixed during the process as well using different metal powders.

Same goes for plastics, though the custom compounds are usually not mixed by those operating the printer.

Economically of course is subjective, and would depend on the budget and application.
