3D printed parts

Someone suggested that I have some custom parts done up on a 3D (metal) printer. Yes, sounds good sez I.
I question how good a printed part would be over say a cast iron or sintered metal part? Would it be as strong under load

3D parts are not usually printed in metal. While possible I think having a machine shop make your parts in "3D" would be more common and cheaper. 3D parts are usually some form of plastic.

As far as strength I suppose it has the possibility to be stronger by making alternate layers aligned differently like plywood? Sounds like it could be awesome. I just haven't seen much of it while reading about regular 3D printers.

From experience I have never seen a 3d printer that uses metal. What I have seen and have access to is a 5 axis vertical mill that takes solid blocks of aluminum/mild steel and machines the block down. Usually using a CAD software. What are you trying to have made? The most time consuming part and most expensive is putting it into the software, depending how complicated it is my shop charges $30-60 an hour plus material and machine time.

There are plenty of places on the web that will print stuff in metal. It uses stainless powder that is held together with glue. The printed object is cast in sand, heated and infused with bronze.
The surface is rough so it would need clean up.

Cool I never realized that, now the question is strength? What do you need made? How important is the structural integrity?

I'm hoping printed parts will be a possible solution to NLA or obscenely expensive small batch re-issued parts, particulary interior trim pieces.
