alross2 Posted March 8 Share #1 Posted March 8 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.

Toolmaker Posted March 8 Share #2 Posted March 8 Grainy, if there is such a word. Its no surprise as 3d printing of metal is termed "additive manufacturing". The process is done from grains of metal. It is generally done for very bespoke products and oft times it is more cost effective to machine the parts This video gives a good overview about the process and why it can be expensive. That said, cost are coming down with basic machines now affordable to hobbyists. I'm certainly no expert but have bought sintered metal products in the past. bridgman, BobG, mtaylor and 5 others 8 Link to comment Share on other sites More sharing options...
