Humans exploring Mars will probably get around in a Humvee-sized rover with a pressurized cabin like this one NASA is testing in the Arizona desert. It contains about 70 parts made with a Stratasys production-grade Fortus printer, including pod doors, camera mounts, vents, and housings.
Ann, I just wanted to say. I know I go on and on about this 3D printing, but it just fascinates me to no end. We talked just a few months ago about materials and they are already here. Like you said, it's progressing very fast. I'm just really interested in this.
That person would still need machining knowledge. At least knowledge of the measuring tools. I can see it as a trade school thing. Now instead of going for machining you go for 3D printing. I might be wrong, but it seems possible.
I agree about tight tolerances. The fact that this technology is being used in commercial aircraft and medical applications speaks volumes about its success in achieving consistent, repeatable, very tight tolerances.
One more thought. One thing that comes to mind to me, being an ex-machinist is the precision i.e. tolerances they can hold. I am betting they get better at that. You can print something all day long with whatever material, but if you can't hold certain tolerances then it isn't good for precision work.
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.
