The surge in affordable 3D printing in recent years has allowed hobbyists to craft everything from customized toys to hair to prosthetic duck feet, with the only limit being the creator’s imagination. Now, researchers in Germany are close to achieving a technique that could revolutionize both 3D applications and glassmaking by giving us the power to 3D print glass.
In a study published in Nature this week, Karlsruhe Institute of Technology (KIT) investigator Dr. Bastian Rapp presented a way of manufacturing a “liquid glass” that can be manipulated with 3D printing software and then heated until it’s a useful solid. (Normal glass consists of melted sand made from sheets in molten tin vats.) By making the glass dispensable through 3D printing nozzles, Rapp believes we’ll soon be able to 3D print glass that’s of sufficient quality for lenses, mirrors, and even drinking cups.
Previous attempts to conceive of a new way of glass production via 3D printers haven’t resulted in glass smooth enough for…
