What we know as modern glass can be sourced to Mesopotamia and Ancient Egypt around 4,500 years ago. Innovated by the folks at MIT, the latest leap forward is a glass printing process called G3DP, which prints optically transparent glass. Molten material is heated to 1900°F then squeezed through an alumina-zircon-silica nozzle, allowing for a nearly unlimited number of geometrical arrangements. Naturally, the potential applications within the eyewear, automotive, tech and other industries seem extremely promising. Watch the video below to find out more.
