NIST Scientists Innovate Laser-Based Method for 3D Printing Metal Alloys

Researchers at NIST have devised a novel technique using lasers to whisk molten metal during 3D printing, enabling the creation of challenging metal alloys. This method ensures uniform mixing of different metals, expanding the possibilities for advanced material manufacturing. The team also enhanced X-ray observation techniques to monitor atomic structure changes in real-time, which will accelerate the adoption of metal 3D printing in sectors like aerospace and automotive.
