Emerging Tech News: 3D Printing
16th January 2019

3D printing mimics metal

In this week’s Nature, scientists at the Imperial College London and the University of Sheffield, UK, report how they used 3D printers to create an unusual – and potentially very useful – series of architected materials by borrowing concepts from metallurgy. They deliberately introduce what look like imperfections into 3D-printed plastic and metal lattices, to make them stronger. This strategy mimics on a larger scale the structural compositional imperfections that can enhance the mechanical performance of normal crystalline materials: the lattice of the architected material stands in for the atomic arrangement in a crystal.
