3D graphene: MIT scientists develop super-light, super-strong structure
Weston Williams for The Christian Science Monitor: Many scientists consider graphene to be one of the most potentially useful materials ever created. The atom-thick chain of carbon atoms are strong, light, and promise many applications, from energy storage to pollution removal to waterproof coating.
While graphene has been studied since the 1940s, scientists have had considerable trouble constructing it into a structurally useful form on a three-dimensional level. But now, scientists at MIT have figured out how to build up graphene into useful, 3-D shapes with the potential to be lighter and stronger than steel.
The new research marks an important step forward for the material. The hexagonal structure is essentially an "unrolled" carbon nanotube only an atom thick, usually only functional on a two-dimensional level. Despite this limitation, graphene is more than 100 times stronger than steel, and converting that two-dimensional strength into a structure usable for three-dimensional building materials has for years been something of a holy grail for graphene researchers. And now, scientists may be one step closer to that conversion. Cont'd...

3D printer builds a cube from a vat of goo … using a phone screen
Ed Oswald for DigitalTrends: What if we told you that you could be holding in your hand a key piece to your next 3D printer? If Taiwan-based 3D-printing startup T3D has anything to do with it, your smartphone will have you creating 3D objects in no time. While the printing surface contains a mechanically operated plate that is dipped into a special resin, it’s your smartphone that tells it how to operate.
From within the printer’s app, you select the shape you’d like to print. From there, the light from the screen moves through a series light patterns necessary to create the object in a special light sensitive resin. While it works a bit slow — as you can see, the cube structure in the video demo above takes over seven hours to print on an early prototype — it’s like nothing we’ve seen before. Cont'd...
3D Printing from Prototype to Production
As more manufacturers are encouraged by the idea of 3D printing, they realize the limitations of the process, as 3D printing still needs refinement in its materials, finish, durability, cost and speed before it can be utilized for mass production.
Dubai Govt, US startup to team up for 3D printing
Paromita Dey for Construction Week Online: The Dubai Government is set to collaborate with US-based startup, Cazza Construction Technologies, to aid 3D printing in the country through the company's construction automation technologies.
According to the 'Dubai 3D Printing Strategy', which was launched by UAE Vice President, Prime Minister and Ruler of Dubai, Sheikh Mohammed bin Rashid al-Maktoum in April this year, 25% of the buildings in the emirate will be based on 3D printing technology by 2030, and this percentage will rise with the development of global technology as well as growth of market demand.
Chris Kelsey, CEO of the Silicon Valley-based startup, said: “We were one of many groups invited to showcase our technologies in Dubai. The government has been looking around the world, whether it was companies from the Netherlands, China, Russia, or the USA to see the upcoming technologies involving construction automation and 3D printing.

Using 3D Printing, Lithography & Soft Robotics: New Prosthetic Hands Made for $50 at Cornell
Bridget Butler Millsaps for 3DPrint.com: What’s so incredible about the soft robotic hand created by a team at Cornell? It can grip, sort, and sense what it is touching. But what’s truly astounding is the potential it offers in terms of price and prosthetics for the future. Bringing forth further innovation and progress to the world of robotics, at $50 one can see how it might have realistic, significant impact on numerous levels.
Dispelling the idea of robots as lovable but clunky machines with a steel and rigid grip, Cornell researchers have managed to create what looks like—and offers the feel of—a human hand. This means that the task list for robots may expand exponentially as they are able to handle more delicate items, to include items like food and other fragile products. This also means that they would be able to work with people without injuring them, such as in a medical setting. Cont'd...

Tough PLA is an engineer's material. You can make truly high-strength, high-wear prototypes or even durable end-use parts like jigs and fixtures.
Spanish City Installs 3D-Printed Bridge
Jen Kinney for Next City: Alcobendas, Spain, this week unveiled a 3D-printed pedestrian bridge, reports 3ders.org, a 3D printing news site. The approximately 40-foot concrete bridge is made up of eight separate parts that fit together, and was created using an additive manufacturing process. It spans a small canal in Castilla La Mancha Park.
According to a statement from the Alcobendas City Council, the 3D printing process resulted in far less waste than normally produced while creating concrete structures, making it less expensive than traditional processes.
Large-scale 3D printing holds the promise of versatility — since structural elements can be created without molds or forms — and of sustainability, since raw material can often be recycled and fewer resources are required during manufacture. Cont'd...

The Rise and Fall of the Everyman Tycoon
Article about the rise and fall of MakerBot by Andrew Zaleski at Backchannel:
Itwas October 2009 when Bre Pettis — his unmistakable sideburns and dark-rimmed rectangular glasses framing his face — took the stage at Ignite NYC, threw his hand in the air, and shouted “Hooray!” two times. A PowerPoint slide lit up behind him, revealing a photo of a hollow wood box crisscrossed with wiring. Bouncing up and down, his profuse mop of graying hair flopping about, Pettis began: “I’m going to talk about MakerBot and the future and an industrial revolution that we’re beginning — that’s begun.”
A former art teacher, Pettis had emerged as a key character in the growing maker movement of the late 2000s, a worldwide community of tinkerers who holed away in makeshift workshops and hackerspaces, equally at home with tools like old-school lathes and contemporary laser cutters. Pettis had begun his ascent in 2006, producing weekly videos for MAKE magazine—the maker movement’s Bible—that featured him navigating goofy tasks such as powering a light bulb with a modified hamster wheel. In 2008, he cofoundedthe NYC Resistor hackerspace in Brooklyn. By then, Pettis was a star. A year later, he launched a Brooklyn-based startup with friends Adam Mayer and Zach Smith (also a NYC Resistor cofounder) called MakerBot... (full article)
