I have to admit that I'm somewhat fascinated with 3-D printing. What do y'all think about it? Do you think it will change the world as some are suggesting or is it just being over hyped? http://hbr.org/2013/03/3-d-printing-will-change-the-world/
I'll have to find links later but current and potential applications are mind boggling. A researcher at Wake Forest (?) has used a 3D printer and stem cells to print replacement organs and I read an article last week suggesting that 4D printers may be on the horizon.
NASA and JPL are looking at creating robots that will land on the moon and use a 3D printer to create a domed moon-base with the dust from the moon. There's a kid who built a robotic arm using parts made with a 3D printer because he thought it would interesting to make. These printers costs about $1500 for the cheap models. I remember when my first color printer cost almost that much as a kid. I cannot wait until I can afford to buy one...
In many ways, current 3D printers are like the old dot-matrix printers in the dawn of personal computing. They make objects, but they are still pretty coarse. Resolution will have to improve manyfold before this replaces casting, forming, and machine tools. Time will tell.
Here's the link to a TED Talk about 3D printing a kidney. http://www.ted.com/talks/anthony_atala_printing_a_human_kidney.html Here's the link to an article and video about 4D printing. http://www.smartplanet.com/blog/bulletin/the-next-big-thing-4d-printing/13898 Absolutely. In fact, I was thinking the exact same thing when I posted the first time in this thread. If, and I realize that's a big if, the speed and resolution take the same leaps that printers have taken, we'll see something like the replicators on Star Trek TNG. Just as an example, over the weekend I was preparing for a trial and had to print so many documents that they filled 2 two inch binders. With an old dot matrix printer that would have been a day long (if not longer) project. With the ink jet I used when I opened my practice, it would have taken several hours (and a few cartridges to boot). With the middle of the pack laser printer I now use, it took about 30 minutes.
