Indeed, Debera, 3D printing is proving to have far-reaching applications, maybe more than people imagined it would initially. Check out this slideshow I did on 3D printed body parts...this is the future! It's pretty incredible: http://www.designnews.com/author.asp?section_id=1386&doc_id=263240
Isn't this just amazing work? Soon enough people will be able to have brand new teeth that fit their gums the perfect way and a fast and efficient manner. Long live 3d printing. At this point it's beyond imagining how far this technology could go. There are some great reviews about that on this local site. A lot of people might find it quite informative.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
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.
