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...

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)

Researchers 3D print working drone with embedded electronics
The Engineer: Researchers at Nanyang Technological University, Singapore (NTU Singapore) have 3D printed a ready-to-fly drone with embedded electronics using an aerospace-grade material.
The electronics were incorporated in the drone during the 3D printing process, which employs Stratasys’ ULTEM 9085, a high strength, lightweight FDM (fused deposition modelling) material certified for use in commercial aircraft. Cont'd...
Hospital to get first dedicated 3D tissue-printing facility
Steve Dent for enGadget: You still can't get a 3D-printed liver transplant made from your own cells, but an Australian hospital is trying to push the tech into the mainstream. The Queensland University of Technology (QUT) in Brisbane is building a dedicated "biofabrication" space where doctors and researchers can develop tech to model and print cartilage, bone and other human tissue. "It will be the first time a biomanufacturing institute will be co-located with a high-level hospital," said Australian Minister of Health Cameron Dick.
The facility will occupy two floors of the hospital and use state of the art tissue manufacturing tech in surgery procedures. "Our vision for healthcare is that the biofabrication institute will pave the way for 3D printers to sit in operating theaters, ready to print tissue as needed, in our hospitals of the future," Dick said.

Time for Monumental Thinking in Additive
Karen Haywood Queen for AdvancedManufacturing.org: The limits of CAD and CAE tools and the STL file format are holding manufacturers back
As additive manufacturing emerges from a long infancy, the industry is grappling with a key challenge: A file format and design tools from the 20th century are being asked to do 21st century jobs.
“The industry was a hobby industry for 25 years and it’s starting to grow up,” said Kirk Rogers, technology leader at GE.
“You made a 3D model and it had a cool factor—Mickey Mouse or a little chess piece—it was awesome to look at,” said Kenneth Church, CEO of the R&D engineering firm Sciperio, as well as the 3D printing firm nScrypt. “What if I made it functional? Cont'd...
With 3D printers and nanofingers, HP Labs builds a new future
Stephen Shankland for CNet: Get ready for the third chapter in the book of Silicon Valley.
During the first chapter, innovation in Silicon Valley was about atoms, carving up silicon wafers into the electronic transistors that started the computing revolution. The second one, more ethereal, brought the triumph of internet services like Facebook and Google.
To be competitive now, a company must blend both approaches. That's the view of HP Chief Engineer Chandrakant Patel, who rose through the HP Labs ranks over 30 years to secure 151 patents and become the company's chief engineer.
"The 21st century will require Silicon Valley to be a cyber-physical valley," Patel said. Cont'd...

3D printing hack: Researchers crash drone with sabotaged propeller
Conner Forrest for TechRepublic: University researchers were able to sabotage a drone by hacking the computer controlling the 3D printer that made its parts, according to a research paper released Thursday. By changing the design of the propellor before printing, they caused the $1,000 drone to "smash into the ground" and break, shortly after take off.
The paper, titled dr0wned - Cyber-Physical Attack with Additive Manufacturing, was a joint effort from researchers at Ben-Gurion University of the Negev (BGU), the University of South Alabama, and Singapore University of Technology and Design. In the paper, the researchers explained how they committed the cyberattack, and what the attack could mean for the future of 3D printing security.
Using a phishing attack, the researchers gained access to the PC that was connected to the 3D printer. Cont'd...
