Producing high-performance titanium alloy parts 鈥� whether for spacecraft, submarines or medical devices 鈥� has long been a slow, resource-intensive process. Even with advanced metal 3D-printing techniques, finding the right manufacturing conditions has required extensive testing and fine-tuning. What if these parts could be built more quickly, stronger and with near-perfect precision? A team comprising experts from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and the Johns Hopkins Whiting School of Engineering is leveraging artificial intelligence to make that a reality.
