CHARLOTTESVILLE, Va. (NRAO PR) — Recent advancements in 3D printing (also known as additive manufacturing) for metallic structures make it possible to print all-metal electromagnetic devices—like antennas and waveguides—on demand. A new partnership between the National Radio Astronomy Observatory, headquartered in Charlottesville, Virginia, and Optisys, LLC, headquartered in West Valley City, Utah, will explore the potential for leveraging this technology for radio astronomy applications.
