  • Machine learning could be key to producing stronger, less corrosive metals
    on August 8, 2017 at 6:55 pm

    Researchers have studied grain boundaries for decades and gained some insight into the types of properties grain boundaries produce, but no one has been able to nail down a universal system to predict if a certain configuration of atoms at grain boundaries will make a material stronger or more pliable. An interdisciplinary team of researchers have cracked the code by juicing a computer with an algorithm that allows it to learn the elusive 'why' behind the boundaries' qualities. […]

  • Software lets designers exploit the extremely high resolution of 3-D printers
    on August 4, 2017 at 4:39 pm

    Today's 3-D printers have a resolution of 600 dots per inch, which means that they could pack a billion tiny cubes of different materials into a volume that measures just 1.67 cubic inches. Such precise control of printed objects' microstructure gives designers commensurate control of the objects' physical properties. But evaluating the physical effects of every possible combination of even just two materials, for an object consisting of tens of billions of cubes, would be prohibitively time consuming. A new software lets designers exploit this issue of extremely high resolution. […]
