Safety has a price and, though expensive, deliberately crashing cars remains a good way of testing an automobile's safety features. However, there is a new crash simulation facility that promises a decrease in the number of cars destroyed during tests. Developed by the German company Instron, and recently installed at BMW in Munich, the non-destructive method relies on reverse acceleration. To work, the car mounts on a rail-borne slide. A hydraulic catapult accelerates the car backwards, producing 70g shock levels. Controlled by the Siemens PC-based SIMATIC WinAC, which communicates with the system via the Profibus-DP and AS interfaces, the process uses reference traces of the motion parameters derived from actual destructive crash tests. The only difference is that they are "replayed" in reverse. Optical and electrical sensors, mounted on the slide, record performance of the car's safety equipment. Not only does the system save money and metal, it allows more frequent testing. Contact Juergen_Kraemer@instron.com or visit www.instron.com/ist.

The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
