Researchers find a way to 3D print whole objects in seconds

by Rachel England, engadget

The new technique could have important medical applications.

When you think of 3D printing, you probably imagine a structure being created layer by layer, from the bottom up. Now, researchers from Switzerland’s Ecole polytechnique fédérale de Lausanne (EPFL) say they have developed a completely new way of creating 3D objects that offer remarkable resolution “in record time.”

MIT scientists made a shape-shifting material that morphs into a human face

by Jennifer Ouellette, ARSTechnica

New method based on double-curvature effect described by Gauss nearly 200 years ago.

The next big thing in 3D printing just might be so-called “4D materials” that employ the same manufacturing technique but are designed to deform over time in response to changes in the environment, like humidity and temperature. They’re also sometimes known as active origami or shape-morphing systems. MIT scientists successfully created flat structures that can transform into much more complicated structures than had previously been achieved, including a human face. They published their results last fall in the Proceedings of the National Academy of Sciences.

3D-printed Mars habitat could be a perfect fit for early SpaceX Starship colonies

by Eric Ralph, TESLARATI

Space architecture startup AI SpaceFactory achieved second place in the latest phase of a NASA-led competition, pitting several groups against each other in pursuit of designing a 3D-printed Mars habitat and physically demonstrating some of the technologies needed to build them.

3D-printed heads let hackers – and cops – unlock your phone

by Zack Whittaker, TechCrunch

There’s a lot you can make with a 3D printer:  prosthetics, corneas, firearms — even an Olympic-standard luge.

You can even 3D-print a life-size replica of a human head — and not just for Hollywood. Forbes reporter Thomas Brewster commissioned a 3D-printed model of his own head to test the face unlocking systemson a range of phones — four Android models and an iPhone X.

Scientists create 3D-printed objects that can change shape after they’re printed

by John Biggs, TechCrunch

3D printed plastics tend to remain pretty stable over time. For example, your 3D-printed Yoda won’t turn into a Chewbacca head without some severe plastic trauma… until now. Scientists at MIT have created a 3D printing technique that allows you to change the polymers in an object after printing. This means you can grow or shrink and object, change its color, and even change its shape completely. Continue reading Scientists create 3D-printed objects that can change shape after they’re printed
