Working gun made with 3D printer
6 May 2013Last updated at 06:38 GMT By Rebecca Morelle Science reporter, BBC World Service, Texas The BBC's Rebecca Morelle saw the 3D-printed gun's first test in Austin, Texas The world's first gun made with 3D printer technology has been successfully fired in the US. The controversial group which created the firearm, Defense Distributed, plans to make the blueprints available online. The group has spent a year trying to create the firearm, which was successfully tested on Saturday at a firing range south of Austin, Texas. Anti-gun campaigners have criticised the project. Europe's law enforcement agency said it was monitoring developments. Victoria Baines, from Europol's cybercrime centre, said that at present criminals were more likely to pursue traditional routes to obtain firearms. She added, however: "But as time goes on and as this technology becomes more user friendly and more cost effective, it is possible that some of these risks will emerge."

Christian School With Creationist 'Science' Quiz Closing Down For Financial Reasons Blue Ridge Christian Academy, the school that made headlines after one of its creationist "science" quizzes was posted online, is officially closing down, according to the Travelers Rest Tribune. The private, religious South Carolina school received attention in April when one of its science quizzes was posted on Reddit and subsequently went viral. The quiz, which was meant for fourth graders and titled “Dinosaurs: Genesis and the Gospel,” affirmed creationist beliefs, including the notion that dinosaurs and humans previously roamed the earth together and that God created dinosaurs. While the school received an onslaught of criticism for the quiz, administrators also thought the attention could be a blessing in disguise. By late May the school had received about $15,000 from more than 70 countries. Teacher Bernice Buchanan noted the school was in deep financial trouble due to the fact that 40 percent of its 139 students received scholarships. (Hat tip, Patheos) LOOK at the quiz:

What, Exactly, Is a 3-D Printer? The world's first 3-D printable handgun, aka "The Liberator." Photograph from Defense Distributed via European Pressphoto Agency This week a 25-year-old law student at the University of Texas named Cody Wilson made international headlines when he used a 3-D printer to "print out" a functional .38 caliber pistol. He then put design software online so that—in theory, at least—anyone in the world who downloaded the software and had access to a commercial 3-D printer and $60 worth of plastic could make their own handgun. It was a demonstration that not only sparked a lively debate on gun control in the U.S. and abroad, but also threw a spotlight on a vibrant, fast-developing manufacturing technology that could change the shape of the future. So what is a 3-D printer? Invented in the mid-1980s, it is a printer that uses plastic, wax, resin, paper, gold, titanium—a whole host of materials—instead of ink to create a solid, three-dimensional object. What can you make with one? Can I do this at home?

I was the Chinese Girl in Tretchikoff's painting - FrontMotion Firefox 6 May 2013Last updated at 20:19 ET Earlier this year Vladimir Tretchikoff's portrait Chinese Girl, often referred to as The Green Lady, was sold for almost £1m ($1.5m) at auction in London - a reflection of its status as one of the most popular prints ever made. The model, Monika Pon-su-san, recalls what it was like to be thrust into the limelight. One day in 1950, a curly-haired stranger walked into my uncle's laundry in Cape Town, where I worked. He stood there as I served a customer, his eyes fixed on me the whole time. "Hello!"

3D printing: A force for revolutionary change 21 May 2013 Last updated at 19:00 ET May the prints be with you: A recent example of a 3D-printed object It was Neil Gershenfeld who introduced me to the potential of additive manufacturing, also known as 3D printing, getting on for 10 years ago, and I got very excited about its possibilities. And now, years later, here he is, trying to dampen my enthusiasm. Professor Gershenfeld has been one of the stars of Massachusetts Institute of Technology MIT for a long time. Under its founder Nicholas Negroponte, the MIT Media Lab was one of the definers of the new digital era: a world where bits and bytes take over from atoms in many familiar activities and where everything that can be digitised will be digitised. “ Start Quote 3D individualises industries which until now have been dominated by mass production” End Quote In 2002 Neil Gershenfeld spun off from the Media Lab something called The Centre for Bits and Atoms. The Centre for Bits and Atoms is where I first encountered a 3D printer. "Ouch!"

Abuse awareness poster is 'only fully visible to children' - FrontMotion Firefox 6 May 2013Last updated at 15:18 GMT From the view of the average 10-year-old, more information is displayed on the poster A poster than can only be fully seen when looked at from a child's point of view has been used in an anti-child abuse campaign. Spanish organisation the Anar Foundation used lenticular printing - a technique which means those looking at different angles see a different image. On the poster, a "secret" message showing a child helpline would show up when seen from a child's height. The foundation said it helped children gain confidence to call the number. The campaign was designed get the information about where to find help to children who may be accompanied by their abuser. Seeking help The foundation worried that if a poster containing a phone number that both adult and child could see, the adult may possibly say things to dissuade the child from considering seeking help. Lenticular printing can also be used to produce a 3D effect
