## Pulsed Arc 3D Printing Produces Meter-Tall Titanium Single Crystals
A group of researchers from institutions in China and the United States has 3D printed titanium alloy single crystals that reach a meter in height. Large single crystals have typically been out of reach for metal additive manufacturing (metal AM), and the study, published in Nature, describes a way past that barrier. Single-crystal metals perform…
