Opel is in the news almost weekly for financial reasons. But the German-based subsidiary of General Motors is also making some technical news. Opel joined with Recaro, a Tier II seat maker, and BASF to develop an all plastic car seat that eliminates the requirement for a steel frame.
The seats are low weight while offering high mechanical strength, good ergonomic properties and a sporty look. The seat pan is made of Ultramid B3ZG8, a very tough yet stiff PA6. Ultramid B3G10 SI is used in the large, free-standing backrest shell as well as in the crossbar. The insert for the backrest shell is made of Neopolen P 9225 K (EPP), an energy-absorbing foam that also covers edges and serves as a module carrier for motors and seat components such as the spinal column support.
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
A tiny humanoid robot has safely piloted a small plane all the way from cold start to takeoff, landing and coming to a full stop on the plane's designated runway. Yes, it happened in a pilot training simulation -- but the research team isn't far away from doing it in the real world.
Some in the US have welcomed 3D printing for boosting local economies and bringing some offshored manufacturing back onshore. Meanwhile, China is wielding its power of numbers, and its very different relationships between government, education, and industry, to kickstart a homegrown industry.
