@Broadway -- I agree, when I think "printing" I think flat pages spewing out. Even having seen a demo of one of these 3D printers in action still makes this hard to get the mind around when we're talking about applying it in the medical and space fields, for example!

For some reason I really have difficulty wrapping my head around 3-D printing. Perhaps I need to actually finally see it in action to appreciate it. I also think it could be the term "printing." I think it's a term still tied to dot matrix and roller holes that you have to tear off the edges of the paper. At least for me the semantics don't match the optics, or something like that.

Hi Leo, right -- 3D printing, increasingly sophisticated robots ... we can bring manufacturing back to the US, but not the actual jobs. There's the upside and the downside of automation and advanced technology!

It will be interesting to see how this all plays out. Some aspects will be slower than we hope, but other areas will leap surprisingly forward. It will probably still be cheaper to stamp out high volumes of "unnecessary plastics objects" (as Nanci Griffith calls them) in China for for some time, but I can see the time coming when, for most plastic objects, necessary or unnecessary as the case may be, where human labor makes NONE of them, we simply make (and repair) 3D printers, and the printers make all the "stuff". Nothing terribly new, just one machine substituting for another, but in this case, for many other machines that used to constitute an assembly line. The 3D printer becomes a "universal" machine in the Turing, 'universal computer', sense.

I thought this was a pretty interesting development: "For the first time, scientists have developed a way to make organs transparent to light while keeping them intact, providing a detailed glimpse of their inner structure." As reported by Yahoo! News, being able to "see the fine detail to be able to see the fine detail and the big picture at the same time" is apparently a "major unmet goal in biology," the study leader Karl Deisseroth said. Here's a video showing a transparent mouse brain!

Leo, interesting post! I had the opportunity to see a 3D printer in action last year while attending an engineering open house at the University of Illinois. Quite impressive. I think I even have a 3D-printed tchotchke around here somewhere!
