3D Printers are cropping up all over. One of the latest that has caught my eye is the Realizer Gold 3D Printer. Yes, it 3d prints in actual gold. Using standard .stl model formats. The Realizer 3d metal printer can build very complex shapes and patterns. The Realizer 3d printer uses (SLM) or Selective Laser Melting to bind a variety of metals. A high power laser melts ultra fine layers of metal powder. The process stacks layers in this fashion creating a 3d dimension metal object. Check out the links to Realizer 3d metal printer here:
