According to Interesting Engineering, researchers at the Fraunhofer Institute for Casting, Composite and Processing Technology developed a 3D printing process capable of depositing multiple metals within a single build cycle. The significance is not just that it prints metal, lots of systems do that. The significance is that it handles different alloys in one continuous process. From a builder perspective, that is the difference between assembling a rocket part from sub-components and growing it as one integrated structure. The time savings reported are measured in weeks, not days.
