Will additive manufacturing/3D printing processes accelerate?

This image, taken under the synchrotron at Argonne National Laboratory, shows a keyhole void about to be formed during the metal 3D printing process. During laser powder bed fusion, a 3D printer drills a hole into the metal. Argonne/Carnegie Mellon research identifies causes for 3D printing defects, eliminating tiny pockets causing problems and paves the way for better results. Additive manufacturing’s/3D printing’s (AM/3DP) promise to revolutionize industry is constrained by a widespread problem: tiny gas pockets in the final product, which can lead to cracks and other failures. Research, led by teams from Carnegie Mellon University and the U.S. Department of Energy’s (DOE) Argonne National Laboratory , identifies how and when these gas pockets form, as well as a methodology to predict their formation – information that could dramatically improve the 3D printing process. “The research in this paper will translate into better quality and better control in working […]
