For those familiar with Mcor's 3D printers, you know that their machines print objects in fully-color out of normal 8 1/2 X 11 office paper. This paper can be brand new or already printed on. For one company, they are using these printers to print out an entire like of jewelry. Currently they are printing 100 pieces per month (utilizing 1500 sheets of reclaimed paper). The end results look like real metal jewelry. Read and see more at: http://3dprint.com/80684/mcor-3d-printed-jewelry/
