Mars-like soil makes super strong bricks when compressed
Elon Musk's vision of Mars colonization has us living under geodesic domes made of carbon fiber and glass. But, according to a study recently published in the journal Scientific Reports, those domes may end up being made of brick, pressed from the Martian soil itself.
3D-printed ceramics and metals might finally arrive this year
Remember 3D printing? A couple years ago it was hotly tipped to revolutionize manufacturing, since you could have a whole factory in your home! Except, really, it wouldn't, because spending hundreds or thousands of dollars on a box to make cute plastic doodads wasn't really what most folks wanted. A few years later, having a 3D printer at home is still generally unnecessary, but that may change, and soon. Ish.
DARPA to develop best practices for 3D printing
Just as steel's physical properties change depending on how it's produced, so too do 3D printed materials. However, unlike steel, we don't yet fully understand how different these newfound techniques affect the resulting printed item. Sometimes a printed item -- even if it's made from something common like aluminum -- ends up having a very different microstructure had it been created with traditional, subtractive methods. You can see an example of that below. Heck, even using the same material on different printer models can result items with wildly divergent properties. But DARPA is looking to change that. The DoD's advanced research agency announced Friday that it is launching an Open Manufacturing program to create comprehensive reference documentation for 3D printing and usher in an era of productive predictability.
Someone's trying to 3D print (most of) a car in six days
You can probably get quite a bit done by yourself in six days time, but could you build an entire car from scratch and take it for a test drive? Probably not. The folks at Local Motors are pretty confident that their 3D-printed car can roll out of Chicago's McCormick Place and go for a spin this Sunday, though. Printing started a few days ago at the International Manufacturing Technology Show in The Windy City, using carbon-reinforced plastic and a Big Area Additive Manufacturing printer, according to 3DPrint. Not everything on the car can be 3D printed mind you, that'd just be crazy. The Strati still needs a battery, engine, wiring and suspension, which, as IGN notes, will be sourced from a handful of suppliers rather than being manufactured onsite. If all goes according to plan, Local Motors hopes to offer "production-level" 3D printed vehicles in the coming months. It isn't an Aston Martin, to be sure, but aside from a DB4, what is?
Robots, guns and pizza: A field guide to the 3D-printed world
Sure, 3D printing is such a tech industry buzzword that you'd have to turn a blind eye and deaf ear to escape news of its impending onslaught. But there's good reason for all the fanfare: 3D printing is poised to upend current manufacturing standards by making industrial fabrication methods democratic. Imagine: Any object you want or need can be (somewhat) instantly "printed" at home. Let that sink in for a bit. The kicker is -- that future is already here, albeit in a minor form, and it's rapidly evolving to be not only affordable, but also practical for everyone and every industry. Need proof?

Not just for figurines: 3D printing saves companies big
While we're monkeying with our MakerBots, large corporations have much better toys to play with. They insist on calling them "additive manufacturing" machines but, truth be told, they're just Replicators with a superiority complex. They sinter or melt powdered or solid metals using lasers or electron beams, then deposit them in layers to form objects. Companies were previously leaning on such (incredibly expensive) devices for rapidly building prototypes like the Audi concept car shown above. Though that's still a huge part of the industrial 3D printer business, the machines are now churning out finished products as well.
3D printing gets metal with European Space Agency's AMAZE project
If you're invested in the future of 3D printing, the London Science Museum was the place to be today, as the European Space Agency and its partners hosted a consortium to celebrate the launch of the AMAZE project. AMAZE, which stands for Additive Manufacturing Aiming Towards Zero Waste & Efficient Production of High-Tech Metal Products (we guess AMATZWEPHMP just didn't have the same ring to it), is a joint effort to take the next logical step in the evolution of 3D printing: manufacturing metal parts. At today's event, components made of tungsten alloy were a particular highlight, as the extremely high temperatures such material can withstand (up to 3,000 degrees Celsius) would make them ideal for use in spacecraft and nuclear fusion environments. The process of 3D printing metal would also allow engineers to design beyond the limits of traditional metal casting, as seen in the Airbus hinges above. If your consortium invitation got lost in the mail, fear not. The museum's exhibit will be open to the public until July of next year.
Formlabs FORM 1 high-resolution 3D printer spotted in the wild, we go eyes on (video)
Last time we checked in with the 3D printing upstarts over at Formlabs, their Kickstarter was doing splendidly, having over doubled its initial funding target. Well, less than a month later, and with the money still rolling in, the current total stands (at time of writing) at a somewhat impressive $2,182,031 -- over 20 times its initial goal. When we heard that the team behind it, along with some all important working printers, rolled into town, how could we resist taking the opportunity to catch up? The venue? London's 3D print show. Where, amongst all the printed bracelets and figurines, the FORM 1 stood out like a sore thumb. A wonderfully orange, and geometrically formed one at that. We elbowed our way through the permanent four-deep crowd at their booth to take a closer look, and as the show is running for another two days, you can too if you're in town. Or you could just click past the break for more.
Ask Engadget: best online 3D printer?
We know you've got questions, and if you're brave enough to ask the world for answers, then here's the outlet to do so. This week's Ask Engadget inquiry is from Paul, who wants to experiment with additive manufacturing that's beyond the capacity of his Makerbot. If you're looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com. "Hi! I'd like to prototype some seriously complex jewelry and my Makerbot isn't up to the task. Can someone suggest a good online 3D printing service that also offers international shipping? Thanks!" 3D printing is so new that no service has made a name for itself above all others, so let's throw it open to the world's finest minds, our trusty readers. Hold your breath, count to ten, feel the Earth move... and then share your experiences in the comments below.
FORM 1 delivers high-end 3D printing for an affordable price, meets Kickstarter goal in 1 day
A $2,300 3D printer isn't really anything special anymore. We've seen them as cheap as $350 in fact. But all those affordable units are of the extrusion variety -- meaning they lay out molten plastic in layers. The FORM 1 opts for a method called stereolithography that blasts liquid plastic with a laser, causing the resin to cure. This is one of the most accurate methods of additive manufacturing, but also one of the most expensive thanks to the need for high-end optics, with units typically costing tens-of-thousands of dollars. A group of recent grads from the MIT Media Lab have managed to replicate the process for a fraction of the cost and founded a company called Formlabs to deliver their innovations to the public. Like many other startups, the group turned to Kickstarter to get off the ground and easily passed its $100,000 within its first day. As of this writing over $250,000 had been pledged and the first 25 printers have already been claimed. The FORM 1 is capable of creating objects with layers as thin as 25 microns -- that's 75 percent thinner than even the new Replicator 2. The company didn't scrimp on design and polish to meet its affordability goals either. The base is a stylish brushed metal with the small build platform protected by an orange plastic shell. There's even a companion software tool for simple model creation. You can still get one, though the price of entry is now $2,500, at the Kickstarter page. Or you can simply get a sneak peek in the gallery and video below. %Gallery-166660%
