I'm bored today so I was reading up on 3D printing and am surprised by what they already have done... basically, as the name suggests, you print 3D objects from a printer, layer by layer using powder (or something like that.) Doesn't sound impressive, and my friends weren't as I was talking to them (they weren't too interested) but it isn't just some shoddy stuff you can print out, they've actually printed out some crazy model airplanes:
That thing would probably cost hundreds or thousands of dollars, but after getting the printer, the materials needed to print it from the computer files isn't much at all, and the price will only go down. People are even working on projects where you can print almost all of a 3D printer from a 3D printer:
Maybe it's all just a flop, but I really see this becoming a household item in the near future, maybe 10 years or so. The crude ones now are only a couple thousand USD, the good ones (ones that can print metal IIRC) are up to a million USD, but I think one day you can simply download the blueprints for an Ipod or something and print it out... they are already working (or have already invented) ways to print actual circuit boards from 3D printers.
None of my friends seem to care, but I know there are enough tech geeks on this forum to at least get 1 response What do yall think??
