3-D printing with metals

   The Researchers team from the university of Twente has found a way to 3D print structures of copper and gold ,by stacking small metal droplets.These droplets are made by melting a thin metal film using a pulsed laser.
    3-D printing is also referred as"New cornerstone of the manufacturing industry"It is limited to plastics. We know that the metals conduct electricity and heat .
   Therefore ,3-D printing in metals would allow manufacturing of entirely new devices and  components such as small cooling elements or connection between stacked on smartphone
