I ordered three Schnellboote propellers printed in metal from Shapeways. There are extremely well done, much nicer than a casting. The quality is dependent on the skill of the designer with CAD tools.

Has anyone purchased any 3-D parts printed in metal? If so, how would you describe the surface finish? We're considering using 3-D for making casting masters but they have to be brass or aluminum to withstand our mold-making process.
