Novel etching technique enhances absorptivity of powders for metal 3D-printing
In a significant advancement for metal additive manufacturing, researchers at Lawrence Livermore National Laboratory (LLNL) and their academic partners have developed a technique that enhances the optical absorptivity of metal powders used in 3D printing. The approach, which involves creating nanoscale surface features on metal powders, promises to improve the efficiency and quality of printed metal parts, particularly for challenging materials like copper and tungsten, according to researchers. Additive manufacturing (AM)—more commonly known as 3D printing—has transformed the way products are designed and produced, allowing for the creation of complex geometries and customized components that traditional manufacturing methods struggle to achieve.
