3D-printed bicycle rivals modern aluminum frames

We’ve seen all sorts of objects printed from 3D printers, but the European Aerospace and Defence group (EADS) has shown off the first bike made from nylon—which they’re saying could replace traditional steel and aluminum bikes due to the affordable method it’s created.

The new manufacturing process is known as Additive Layer Manufacturing (ALM) and it allows single products to be grown from a fine powder of metal (such as titanium, stainless steel or aluminum), nylon or carbon reinforced plastics. Drip by drop, each part of the bike is made from powder with the machine connected to a computer loaded with the CAD bike design.

Aluminum bikes are already pretty light, but EADS is saying their nylon Airbike is 65 percent lighter. It’s also more eco-friendly to produce, and due to the nature of 3D printing, individual parts can be printed easily if damaged.

Andy Hawkins, lead engineer for ALM at EADS, described it as ‘a game changing technology’. "The beauty is that complex designs do not cost any extra to produce," he said. "The laser can draw any shape you like and many unique design features have been incorporated into the Airbike such as the auxetic structure to provide saddle cushioning or the integrated bearings encased within the hubs."

By removing production lines and the need for factories, Hawkins believes the costs of ‘manufacturing’ will be significantly reduced and, through this, ALM has the potential to reverse trends of urbanization that have historically accompanied industrialization.

3-D Printing Spurs a Manufacturing Revolution

SAN FRANCISCO — Businesses in the South Park district of San Francisco generally sell either Web technology or sandwiches and burritos. Bespoke Innovations plans to sell designer body parts.

The company is using advances in a technology known as 3-D printing to create prosthetic limb casings wrapped in embroidered leather, shimmering metal or whatever else someone might want.

Scott Summit, a co-founder of Bespoke, and his partner, an orthopedic surgeon, are set to open a studio this fall where they will sell the limb coverings and experiment with printing entire customized limbs that could cost a tenth of comparable artificial limbs made using traditional methods. And they will be dishwasher-safe, too.

“I wanted to create a leg that had a level of humanity,” Mr. Summit said. “It’s unfortunate that people have had a product that’s such a major part of their lives that was so underdesigned.”

A 3-D printer, which has nothing to do with paper printers, creates an object by stacking one layer of material — typically plastic or metal — on top of another, much the same way a pastry chef makes baklava with sheets of phyllo dough.

The technology has been radically transformed from its origins as a tool used by manufacturers and designers to build prototypes.

Protect Against Kiosk-Propagated Viruses

Public kiosks, such as those used for photo printing, are exposed to thousands of USB drives and other media every month. Many of them are poorly secured and are using your media as a virus-propagation tool. Protect yourself with these simple steps.

Security blog Risky.biz reader Morgan wrote in to highlight how an unsecure photo kiosk at Big W—a Woolworth subsidiary—infected one of his flash drives with a virus.

Photo kiosks in Big W stores are allegedly infecting customers with USB-borne viruses.

The Windows-based Fuji photo kiosks located in the company’s stores apparently don’t run antivirus software, so lovely little bits of malicious software like Trojan.Poison-36 are winding up on customers’ USB keys, according to Risky Business listener and blogger Morgan Storey.

On its own, an isolated incident of a photo kiosk infecting a USB device might not be newsworthy. But what makes this item stick out is Big W’s reply to Morgan after he notified the company of the issue:

You can visit the full article at the link below to see a screenshot of the entire email but the most notable quote in the their response should give you pause.

Please note that we are currently testing anti-virus software on our Fuji photo kiosks in a number of stores, and if it is successful, we plan on rolling it out to all stores in the future.

It could be debated whether or not the virus Morgan’s flash drive picked up came from that particular photo kiosk but the people in charge of the kiosk acknowledge that the kiosks have no virus protection. All it would take for each kiosk to become a virus propagating machine then—with access to thousands of USB drives, memory sticks, and SD cards a month!—is exposure to one infected flash drive.

Adobe demos multi-platform app created using single code base

Christian Cantrell, a technical product manager at Adobe, has created an app for multiple platforms including OSX, Windows 7, Linux, Android, iPhone OS, iPad OS and browsers – no biggie, right? But here’s the cool bit, all the apps use the same code base. In other words, Cantrell wrote an app once and didn’t have to change it to get it on other platforms, he just needed to apply slightly different platform "wrappers".

From Cantrell’s blog: "The app is called iReverse… Although iReverse is fun to play, the most amazing thing about the project is the fact that it runs in all these different environments completely unchanged. In other words, the exact same code base is used to build versions for five different environments. There’s no other platform in the world that can boast this level of flexibility – not even close."

When one screen is just not enough

Convergence is where it’s at.

A recent article over at Mashable looked at some Nielsen statistics regarding the concurrent use of television and a computer. The general trend indicates that households are growing more comfortable with the idea of using a computer (most likely a notebook) while watching their favorite programs. The surge of real-time social media (like Twitter and Facebook) is probably a big factor.

There have been some neat experiments with convergent programming such as sporting events delivering stats and alternate views during games, adding additional content to repeated shows and of course the ever-present user interaction on Twitter and show bulletin boards.

As multi-platform viewership continues to grow, how will networks and companies take advantage of it?
