I *can* imagine the possibility that within 5 years, we'd have portable enough 3d imagers and powerful enough phones to both stick the hardware in a phone-sized device and have a phone-sized device run the required software. I have no real understanding of how the physics of that would really work, granted, but it doesn't seem totally outside the bounds of possibility.
But that's just the input. I *can't* really imagine the possibility that within 5 years, we'd have powerful enough *printers* to take the output of such a precise scanner, and recreate it anywhere near so precise, even if you're only talking about an object made entirely out of one or two kinds of plastic, which is unlikely to be the sort of object people would really want to "replicate". "Just about anything"? Yeah right.
Wake me up when we can replicate food, say, and have it taste the same as the original. Will we see that in my lifetime? Maybe, if I'm lucky. Will we see that in 3-5 years? I'd bet quite a lot of money on "no", and I'm not a betting sort of person.
