As the world’s first 3D-printed handgun starts to be replicated, authorities are scrambling to react to a technological advancement that only a few weeks ago sounded more like science fiction than fact.. But according to a leaked bulletin by the Department of Homeland Security, any effort to stop the printing of these guns might be in vain.

A May 21 DHS bulletin distributed to several law enforcement agencies across the country, and obtained by Fox News, basically states that there might be nothing that can be done to stop people from downloading and printing plastic guns

“Limiting access may be impossible,” the memo states. Read more…

When a baby was afflicted with a condition that blocked his ability to breathe, professors at the University of Michigan developed a 3D-printed splint that saved the child’s life.

Baby Kaiba Gionfriddo was only six weeks old when he stopped breathing and turned blue, as explained in the video above. Doctors discovered Kaiba had severe tracheobronchomalacia, a condition that causes a collapse of the windpipe, blocking the body’s flow of air. This rare condition affects only 1 in 2,200 babies.

When treatments failed to help, Kaiba’s doctors went to the University of Michigan. That’s where two professors — Dr. Glenn Green, associate professor of pediatric otolaryngology, and Scott Hollister, professor of biomedical engineering & mechanical engineering and associate professor of surgery — used pioneering technology to come up with a solution.

It’s been a big week for 3D-printed weaponry. On Monday, a Wisconsin man announced that he had built a largely plastic gun for just $25. Now, a Tennessee man has designed and printed bullets using the same technology.

In a video posted to YouTube on Sunday, Jeff Heeszel — he goes by taofledermaus on the site and his clips have more than 43 million views — announces that a friend of his sent him several 3D-printed bullets. A shooter then loads one into a Mossberg 590 shotgun and fires at a dartboard.

Amazingly, the plastic slug does some serious damage. But then, the same goes for some of the subsequent bullets fired: Silly Putty, bubblegum, frozen Vienna sausages, etc. Read more…

It’s hard to predict exactly what technologies and trends will transform our lives. Few understood just how powerful the Internet would be, dismantling entire industries and creating millions of jobs.

So what’s the next big thing? Where will the jobs be, and how can companies carve out a competitive advantage in the global economy?

McKinsey’s Global Institute discusses this in its latest report, Disruptive Technologies: Advances that will transform life, business, and the global economy. It came up with a list of 12 technologies that could have a potential economic impact between $14 trillion and $33 trillion a year in 2025. The authors write that “some of this economic potential will end up as consumer surplus; a substantial portion of this economic potential will tranlate into new revenue that companies will capture and that will contribute to GDP growth. Other effects could include shifts in profit pools between companies and industries.”

The 12 disruptive technologies include: mobile Internet, automation of knowledge and work, Internet of things, cloud technology, advanced robotics, autonomous and near-autonomous vehicles, next-generation genomics, energy storage, 3D printing, advanced materials, advanced oil and gas exploration and recovery, renewable energy.

Here’s the breakdown of the 12 technologies and their potential for impact:

And a great chart showing how these technologies will affect the world:

They say necessity is the mother of invention, and nowhere was it more necessary than in the case of Kaiba Gionfriddo’s life. The infant was born with a condition called tracheobronchomalacia that results in weakened support for the trachea, and his fate seemed all but decided until researchers at the University of Michigan proffered an unlikely solution: a 3D-printed tracheal splint. The splint was custom-made just for the child and designed to hold the trachea in place as the bronchus builds around it, giving it strength. In two to three years, the trachea will be able to stand on its own, and the polycaprolactone biomaterial used to create the splint will be absorbed into the body. After a successful operation, Kaiba was taken off ventilator support — and he hasn’t needed it since. From 3D-printed skull prosthetics to this recent innovation, it’s clear 3D printing has a far more noble future than just making pizza.
