Last year, California Institute of Technology (Caltech), Pasadena, California, researchers revealed that they had developed a new fabrication technique for printing microsized metal parts containing features about as thick as three or four sheets of paper. Now, the team has reinvented the technique to allow for printing objects a thousand times smaller: 150 nanometers. These parts can be three-to-five-times stronger than similarly sized structures with more orderly atomic arrangements.

University of California (UC), Berkeley, California, announced mechanical engineering faculty Grace Gu was selected as the inaugural recipient of the Lawrence Livermore National Laboratory (LLNL), Livermore, California, Early Career UC Faculty Initiative for her proposal, " Toward AI-Driven Additive Manufacturing for Metal-Ceramic Composite Structures."

Due to its superior thermal conductivity, copper is one of the “hottest” metals for research and development in additive manufacturing. This is desirable in rockets and industrial applications such as electronics, where heat exchange is critical. Second only to silver among metals in its ability to conduct heat, copper is pound-for-pound significantly less expensive. Copper alloys provide enhanced mechanical properties along with that valuable conductivity.

The U.S. House of Representatives passed the Dept. of Defense Appropriations bill, which includes an amendment supported by U.S. Reps. Mike Kelly (R-PA-16) and Chris Deluzio (D-PA-17) for $10 million for "Neighborhood 91," a comprehensive additive manufacturing (AM) production campus located near Pittsburgh International Airport.

Casio Computer Co., Ltd. announced the release of the latest addition to its family of G-SHOCK shock-resistant watches. The new dust- and mud-resistant MUDMASTER GWG-B1000 features exterior components in metal for a solid, powerful design, made by metal injection molding (MIM).
