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.
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.
TJ, your sci-fi movie scenario sounds just like what NASA envisions--feed everything into it and out comes the perfect replacement part. I'd like to see multi-material (metals + plastic) 3D printers, too. Those may not be so far away, since the architectural types use a wide variety of materials already.
Mydesign, thanks for your enthusiasm. There's a lot going on with 3D printing of metals, more than most people know, since these companies have been very quiet compared to the hobbyist end machines that use plastics.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
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.
