The Additive Manufacturing of metals typically leads to the formation of columnar grain structures along the build direction in most as-built metals and alloys. These long columnar grains can cause property anisotropy, which is usually detrimental to component qualification or targeted applications.In a recent article in Nature Communications ((2020) 11:142), an Australian research team led by Ma Qian and comprising colleagues at the Centre for Additive Manufacturing, RMIT University, Melbourne, and the
