Scientists from Texas A&M University and the U.S. Air Force say they’ve developed a way to 3D print the strongest kind of steel, along with many other metals.By using a steel powder melted into place by a laser, this process follows in the footsteps of technologies like powder welding. And by adding a mathematical model to gauge which laser settings will best reduce printing flaws, the researchers have made a process they say makes strong steel into strong 3D-printed steel items.The mathematical model and its results are presented as an “optimization framework” that anchors the research team’s new paper.“This framework utilizes the computationally inexpensive Eagar-Tsai model, calibrated with single track experiments, to predict the melt pool geometry,” the team writes. “Computationall...

3-D printing is an unstoppable force. Not too long ago, the printing speed and limited output of 3-D printers made them suitable only for rapid prototyping. But in the coming years, 3-D printers will be at the heart of full-scale production capabilities in several industries, from aerospace to automotive to health care to fashion. Manufacturing as we know it will never be the same.
