Nano Dimension has announced that they are collaborating with Tel Aviv University on the development of a nickel nano ink. Nickel is an ideal material for 3D printed electronics, but it's difficult to work with as its particles tend to cluster, clogging up printer nozzles. Researchers at TAU have developed a new method of producing nickel nanoparticle suspensions, however, that eliminates the problem of clumping. The next step is to turn the material into a printable ink. Read more at 3DPrint.com: http://3dprint.com/121079/nanoparticle-nickel-ink/
