Printing Intricate Geometries in Steel (IMAGE) U.S. Army Research Laboratory Caption Using advanced additive manufacturing techniques, Army scientists work with an Air Force-invented steel alloy to print intricate geometries with ultra-high-strength. This sample, created using a technique called powder bed fusion, is the symbol of the newly formed Army Futures Command. The steel is 50 percent stronger than what is commercially available.
