Researchers at Harvard have come up with a way to use LASERs to anneal silver nano-particle liquid into wire that’s thinner then a human hair. This process allow them to eject the silver liquid through a needle and have a laser solidify it instantly to print 3 dimensional wire objects. The video above is fun to watch. Like all current 3D printing systems, this will have a few years of refinement needed before it’s ready for prime time, but it does usher in newer smaller more curvy electronic devices. That sounds cool doesn’t it?
