3d metal printed bodes or frames

Has anyone printed cocker, viking or evil ehm bodies or trigger frames with metal 3d printers?

I known some printers can print aluminum and titanium media.

Anyone have any more info on this technology?

I have no experience with printed metal, but also very curious... I think you can order parts printed in metal from Shapeways? Though I've not done that myself, I think I remember seeing someone on here who has.

It would be cheaper to plastic print, then cast the part from the print. Metal printing is ungodly expensive.

I was actually just talking about this with someone less than an hour ago. I just don't have anything like a forge for melting the metal, or hear treating. Anyone have a good DIY forge setup?

Keep in mind, none of these processes can yet produce the surface finish or tolerances of traditional machining. Especially bodies with internals and moving parts, you'll have just made an extremely expensive rough that will still require finish machining, defeating the purpose.

Don't expect to hold tolerances going from print>DIY mold>DIY casting, either. (shrinkage/warpage/surface finish)

(edit: added reasons why mold/cast isn't ideal either)

I have had things printed in aluminum... It's rough looking and almost sandy in texture.... And porous.

Frames may be possible, but anything that has to hold pressure is a bad idea. In my experience, most 3d printed items cant hold water, let alone pressure. What would you need on a frame that cant be machined? What is the advantage of 3d printing in this case (I can see it for bodies, but not a frame)?

Another thing to consider is that the metal filaments on the market are still plastic but with flakes of metal in them. While they may look good, in many ways, they're actually more brittle than standard plastic filaments. You'd be better off having parts cast or milled than printed in metal.

OP's probably not talking about "metal" FDM printing, but rather DMLS which is true aluminum/bronze/titanium/etc additive manufacturing. Still unsuitable, for all the reasons previously discussed.
