Scientists used machine learning to create a 3D-printable steel with high strength, ductility, and corrosion resistance, outperforming many existing alloys. For years, the metals used in 3D printing have carried a fundamental design flaw, not in the metals themselves, but in their origins. As reported by 3Dprint.com, most of today’s additive metal materials were originally developed for forging or castin... [3848 chars]
