Metal 3D printing introduced a different, new way to fabricate parts. After hundreds of years of metal fabrication limited to cutting and forming operations, the idea of methodically building up raw material into a desired shape was completely foreign to the manufacturing industry. What sorts of parts could a 3D printer produce? Would it make traditional metalworking obsolete? These questions were initially left unanswered due to early printers being extremely expensive and difficult to operate, but more and more applications for metal additive manufacturing have emerged as the process has become more affordable and broadly adopted.
