MIT researchers crack 3D printing with glass — new technique enables inorganic composite glass printed at low temperatures

Researchers from the Lincoln Laboratory at Massachusetts Institute of Technology (MIT) are showing the world that there are still plenty of new innovations to come in the world of 3D printing. We've reviewed really fun 3D printers like the Cocoa Press that 3D prints chocolate, but this is the first time we've seen anyone 3D print with glass.

When making things out of glass the usual way (sans 3D printer), there's a need for extremely high temperatures to not only shape the glass but also anneal the final creation. The thought of parsing hot material like molten glass through a machine sounds unreasonable to manage, and that's because it is. That's why the team at MIT developed a new technique that allows the team to produce glass structures at a much lower temperature.

This inorganic composite glass is made of inorganic materials, with nanoparticles and silicate solution confirmed by the team as part of those materials. Once the glass filament has been printed, it's placed in an oil bath where the temperature is then raised to 250°C. An organic solvent is then used to clean any residue from the print.

We don't expect to see glass filament on the shelves anytime soon, but it's exciting to know this possibility is out there and being actively pursued. In the meantime, we'll stick to what we know best—3D printers that print plastic and chocolate.

    only 250C?
    That is impressive considering the working temperature of glass is around 800~1000C.
    A cooking oven can hit 250C.

    Printing chocolate mentioned in the article, why?

    Don't mess about printing chocolate, just get on with eating it!

    The article is quite wrong about being first to print glass - there have been many publications over the years, and even a company in Germany called Glassomer.

    Also printing Molten pure glass was done in 2015 by MIT mediated matter group :
