I think many of Shapeways metal offerings are castings from prints in wax, e.g. "For Silver, the minimum supported wall is determined by our ability to successfully print your product in wax and then cast it in a plaster mold. Walls that are too thin will break in the mold-making process." [1] 1: https://www.shapeways.com/materials/silver https://www.shapeways.com/materials/silver

Shapeways offers several different processes. The lost-wax stuff is for jewelry, so you can make hollow objects in expensive metals. Laser sintering is used for working parts. There's also MarkForged [1], which has their own process for 3D printing carbon fiber and metal with a sub $100K machine. It's kind of slow, but they're selling it to make dies for injection molding.
