New Process Will Allow You to 3D Print Glass on Demand

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…

Snapchat World Lenses Are the Next Step in Augmented Reality

Since it was founded in 2011, Snapchat has used cutting-edge technology to successfully set itself apart from other photo-sharing services. The app’s latest feature, Snapchat World Lenses, integrates colorful, 3D objects into real-world scenes captured on your smartphone.

As The Verge reports, Snapchat World Lenses were introduced on Monday, April 18. This is the latest experiment with augmented reality we’ve seen from the mobile app. As Snapchat says in a statement:

“We launched Lenses over a year ago as a whole new way to express ourselves on Snapchat. Since then, we’ve become puppies, puked rainbows, face-swapped with our best friends—and begun to explore how Lenses can change the world around us.

Today, we’re adding new ways to use Lenses.”

Unlike most of the app’s high-tech filters, Snapchat World Lenses aren’t designed for faces. They’re meant to be plopped down anywhere in the space being recorded on your phone’s rear-facing camera. That’s where the augmented reality element comes in: The 3D objects behave as if they’re physically in front of you. Move your…
