This new 3D printed glass looks just like pouring honey


The first of its kind optically transparent 3D-printed glass!

Humans have been making glass in various forms for thousands of years, from glassblowing techniques developed by the Roman empire to the industrial methods of the 1950s, floating molten glass on huge baths of melted tin. One particularly ancient process though, in which molten glass is coiled around a solid core, has been revived with the help of modern technology. MIT's Mediated Matter Group has unveiled a new way to 3D print glass, removing the need for a solid core but coiling the material in molten strands just like our ancestors did thousands of years ago.
