New 3D printer tech uses elliptical laser beams to stir molten metal and create ‘alloys-on-demand’ — existing machinery can implement technique in software meaning for more convenient, stronger alloy printing
Researchers at the National Institute of Standards and Technology (NIST) have developed a novel metal 3D printing technique that uses elliptical laser paths to stir molten metal during the printing process. This method, detailed in the journal Additive Manufacturing, allows for the creation of custom alloys on-demand by blending different metal powders in real-time. The innovation requires only a software update to existing machinery, making it a practical advancement for creating stronger and more convenient metal components. AI
