Designers and makers have been busy imagining uses for 3D printers, ranging from casts to houses to duck feet. Vehicle designer Nir Siegel doesn't just want to 3D-print cars, he wants them to assemble themselves.

Siegel's Genesis concept would involve the delivery of a specialized 3D printer to a car buyer. The printer would then print out a car all around itself to match the buyer's specifications.… Read more

It usually goes like this. You break your arm. You get a big plaster cast. Your friends sign it and draw on it. You invest in chopsticks in an attempt to get at the never-ending itches hiding beneath. Designer Jake Evill has a better idea. His Cortex exoskeletal cast concept uses 3D printing to create a custom cast that is strong, lightweight, and full of sweet, sweet air holes.

"After many centuries of splints and cumbersome plaster casts that have been the itchy and smelly bane of millions of children, adults and the aged alike, the world over, we at last bring fracture support into the 21st century," writes Evill, who just graduated from Victoria University of Wellington in New Zealand. … Read more

When he was born in a high school biology lab last November, little Buttercup wasn't like all the other ducklings: His left foot was turned backward, making getting around a bit of a trial for the little guy. Although his caregiver at the school worked on turning the foot around the right way, it couldn't quite get there.

So when he was transferred to Feathered Angels Waterfowl Sanctuary in Arlington, Tenn., new owner Mike Garey realized pretty quickly that something had to be done.

"With his deformed foot, he would have been in pain and had constant cuts and foot infections walking on the side of it even at our sanctuary here, and foot infections on these guys is always a serious matter," Garey said. … Read more

Microsoft showed off some new capabilities for mapping, including 3D imagery and voice command integration, on Wednesday at its Build conference for developers.

Bing VP Gurdeep Singh Pall highlighted some new possibilities with Bing. He told developers that the search engine can now be "a canvas for a whole lot of interesting things."

The Windows 8.1 app will now come with 3D imaging, Singh Pall told developers. He then showed how developers can use the 3D imaging and voice command to create new Bing search experiences. While viewing a demo of a foreign country map, Singh Pall … Read more

We've seen some very sophisticated 3D-printed objects recently, but never a tiny 3D-printed battery -- one that's as small as a grain of sand, no less.

A group of U.S. and Korean researchers has managed to print a lithium-ion microbattery that can fit on the head of a pin.

Although it weighs less than 100 micrograms, it can store as much power per gram as larger Li-ion batteries used in laptops or electric vehicles. It could even power tiny robots or medical devices. … Read more

MakerBot, one of the most well-known desktop 3D printing companies, has been acquired by Stratasys, the companies said Wednesday.

In a release, the companies said it was a stock-for-stock transaction worth about $403 million, based on Stratasys' stock price as of Wednesday. Stratasys will exchange 4.76 million shares of its stock for 100 percent of MakerBot's outstanding stock. By agreeing to be acquired, MakerBot becomes part of one of the leading industrial 3D printing companies. The deal also allows the publicly-traded Stratasys to compete more directly at the consumer level with 3D Systems and that company's Cube … Read more

Australia is known for its overly large bugs, like the up-to-20-inch Titan stick insect. But the country also has tiny insects, like the itsy-bitsy wheat wheevil. Researchers with Australia's national science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), are trying out a method of super-sizing insects through 3D printing.

Small, sometimes nearly microscopic, insects from the Australian National Insect Collection are run through a 3D-scanning system and then printed out at magnified sizes in titanium. Why would you want to do this other than to leave one on someone's seat as a prank? The bigger versions give scientists a better look at the insect's anatomy in order to learn more about their surface characteristics or determine gender. Plus, it's just plain cool.… Read more

In the movie "Iron Man 3," the titular hero struggles in what appears to be a rinky-dink backwater town to find an Internet connection fast enough and big enough to crunch data to find the terrorist villain. The town looks to be Nowhere, U.S.A., but we're told, it is actually Chattanooga, Tenn.

Known to some as "Gig City," the real Chattanooga would have posed less of a problem for Tony Stark's heroic data-analyzing needs. The modest city of half a million has more than 150,000 homes wired for affordable Gigabit Internet. … Read more

I don't get it. I'm gone an entire week and there's not one show. I get back, Justin's gone, but I still have to do one. What's up with that? Luckily it's a non-issue. Today we've got CNET HDTV editor Ty Pendlebury on the program to help me wrap up the chaos that was E3 2013 and filter out some of the new-found disgust I have for videogame fanboys. You know, the worst kind of fanboy.
