Researchers use 3D printer to print glass

For the first time, researchers have successfully 3D printed chalcogenide glass, a unique material used to make optical components that operate at mid-infrared wavelengths. The ability to 3D print this glass could make it possible to manufacture complex glass components and optical fibers for new types of low-cost sensors, telecommunications components and biomedical devices.
