New Operando X-Ray Method Could Give Metal 3D Printing a Real-Time Control Lever

Northwestern University‘s associate professor of mechanical engineering Tao Sun and collaborators have published new research showing that the atomic-level arrangement of liquid metal, not just cooling rate and temperature gradient, governs how grain structures form during laser additive manufacturing.  The findings, published in Nature Communications under the title “Operando X-ray scattering reveals ordering-mediated solidification in…
