3D printing makes single-crystal metals in complex shapes up to one metre long
Nature says the method uses readily available equipment and can make shapes established crystal-growth methods cannot.
TLDR
Nature reports that a 3D-printing method has produced single crystals of metals and alloys in complex shapes and up to one metre long. Its article says the method uses readily available equipment and can create geometries beyond the reach of established crystal-growth methods. Single crystals have uses in technologies including jet-engine turbines, but can be difficult or expensive to make.
