These $10,000 Concrete Homes Are 3D-Printed in Less Than 24 Hours

What makes housing so expensive? Labor costs, for one. According to a 2014 Census Bureau survey, the average single-family home takes about six months to construct, and that's a lot of man-hours. A new type of home from Austin, Texas-based startup ICON and the housing nonprofit New Story is hoping to change that. Their homes can be built from the ground up in 12 to 24 hours, and they cost builders just $10,000 to construct, The Verge reports.

ICON's construction method uses the Vulcan 3D printer. With concrete as the building material, the printer pipes out a structure complete with a living room, bedroom, bathroom, and porch that covers 600 to 800 square feet. That's a little less than the size of the average New York apartment and significantly larger than a typical tiny home.

The project, which was revealed at this year's SXSW festival in Austin, isn't the first to apply 3D printing to home construction. Moscow, Beijing, and Dubai are all home to structures assembled using the technology. What makes ICON and New Story's buildings remarkable is what they intend to do with them: Within the next 18 months, they plan to set up a community of 100 3D-printed homes for residents of El Salvador. If that venture is successful, the team wants to bring the printer to other places in need of affordable housing, including parts of the U.S.

ICON wants to eventually bring the $10,000 price tag down to $4000. The 3D-printed houses owe their affordability to low labor costs and cheap materials. Not only is cement inexpensive, but it's also sturdier and more familiar than other common 3D-printed materials like plastic. The simple structure also makes the homes easy to maintain.

“Conventional construction methods have many baked-in drawbacks and problems that we’ve taken for granted for so long that we forgot how to imagine any alternative,” ICON co-founder Jason Ballard said in a release. “With 3D printing, you not only have a continuous thermal envelope, high thermal mass, and near-zero waste, but you also have speed, a much broader design palette, next-level resiliency, and the possibility of a quantum leap in affordability."

After printing and safety tests are completed, the first families are expected to move into their new 3D-printed homes sometime in 2019.

BioLite Has Designed a Headlamp That Won't Irritate or Slip Off Your Head

Headlamps are convenient in theory. Instead of fumbling with a flashlight or your phone in the dark, you can strap one to your head and walk your dog, do some late-night grilling, or venture around your campsite hands-free.

But in reality, the awkward design—with a bulky light that digs into your skin and slides down your forehead—cancels out much of the product's appeal. Luckily, it doesn't have to be this way, as the folks at BioLite have demonstrated with their reinvented headlamp.

The BioLite HeadLamp 330, which debuted on Kickstarter in 2018 and is now available on Amazon, promises to make you forget you're even wearing it. Inspired by modern wearables, BioLite has retooled various elements of the clunky traditional design to make it as comfortable as it is functional.

The ultra-thin light sits flat against your skull, which means you won't have any painful marks in the middle of your forehead when you take it off. The band itself is made from a moisture-wicking fabric that feels good on your skin, even when you're working up a sweat. And unlike conventional headlamps, BioLite has redistributed the power source to the back of the head in its design, balancing the weight and taking care of any slippage issues.

As is the case with other BioLite products, technology is an essential part of the design. The 330-lumen lamp projects light up to nearly 250 feet in front of you. There are variable lighting settings, too: You can opt for either a white spot or floodlight, both with dimming options, or a strobe light feature; there's also a red floodlight. It can run for three and a half hours at maximum brightness or 40 hours at minimum brightness, and when it needs to be recharged, you can just plug it into a micro-USB source like a solar panel or powerbank.

Get your own BioLite Headlamp for $49 on Amazon. It's available in in ember red, ocean teal, sunrise yellow, or midnight gray.

Bioengineering Student Is Building Custom Prosthetic Arms From LEGO Bricks

The custom LEGO designs built by 19-year-old David Aguilar aren't meant to sit on a shelf. For years he's been ignoring the instructions that come with LEGO sets to make functioning prosthetic arms for himself, and now he's sharing his creations online, Reuters reports.

Aguilar—who lives in Andorra, a small principality on the French-Spanish border—was born with a rare genetic condition that left him without a right forearm. He built his first artificial limb out of LEGO bricks at age 9, and hasn't looked back. Today Aguilar is pursuing an eduction in bioengineering at the Universitat Internacional de Catalunya in Spain, and he's already on LEGO prosthetic No. 4.

After acquiring complex LEGO sets for things like airplanes and construction vehicles, Aguilar reconfigures them into arms and adds electric motors that allow him to move his fingers and bend his elbow. He documents his building process on YouTube under the name Hand Solo. Each arm he builds is named MK followed by the model number (MK I, MK II, etc.), a nod to the MK suits built by Tony Stark in the Iron Man series.

The LEGO prosthetics are more than conversation starters—they're also affordable compared to professionally made robotic limbs on the market. Aguilar tells Reuters his dream is to one day provide cheaper options to prosthetics-wearers like him.
