The TSA mandates that all checked luggage must be locked with a deliberately flawed lock that can be opened with one of a handful of skeleton keys that are supposed to be kept secret. It's been more than a year since the TSA allowed a newspaper photographer to print a high-rez photo of its universal luggage-lock keys, allowing any moderately skilled locksmith to create her own set. Ars Technica downloaded a set of key STL files from Github, printed them on a consumer 3D printer, and showed that they could gain entry to any luggage.
It's a model for what happens with any kind of law-enforcement/public safety back door: the universal keys leak and there's no way to re-key all those locks out there in the field. The FBI and UK security services are calling for backdoors in all crypto -- the code we use to protect everything from pacemakers to bank accounts. This is as neat an illustration of why that's a bad idea as you could ask for. Read the rest

MIT researchers built a 3D printer from just $7,000 in off-the-shelf parts that can print ten different materials at a time. Current multi-material 3D printers generally can only spew out three materials and cost more than $200,000. From MIT News:
MultiFab gives users the ability to embed complex components, such as circuits and sensors, directly onto the body of an object, meaning that it can produce a finished product, moving parts and all, in one fell swoop.
The researchers have used MultiFab to print everything from smartphone cases to light-emitting diode lenses — and they envision an array of applications in consumer electronics, microsensing, medical imaging, and telecommunications, among other things. They plan to also experiment with embedding motors and actuators that would make it possible to 3-D print more advanced electronics, including robots.
