The ability to fabricate parts in space would certainly take the drama out of an Apollo-13 type repair scenario. Instead of scrounging pieces and duct-taping them together, you could make a whole new part, or even a totally redesigned part to deal with the situation.
Nice to know that Pratt & Whitney is working with the University of Connecticut on additive manufacturing. As we've said in previous stories and comments, universities need to be on top of this trend because it's happening so fast. That way, our next generation of engineers will be ready for it.
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.
You can find out practically everything you need to know about engineering plastics as alternatives to other materials at the 2014 IAPD Plastics Expo. Admission is free for engineers, designers, specifiers, and OEMs, as well as students and faculty.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
