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.
Linear guides are one of the most important components required for the design of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides, can enable designed-in functional features.
