@Angilion: Hope you read this! It's a subject that`s fascinated me for ages.

Rather than ripping matter right down to pure energy (Star Trek style) you`d just rip it molecular levels. Ripping molecules apart is REALLY energy-heavy! Producing or requiring a LOT of it!
Ripping matter to small size, the re-arranging it SEEMS to me to be much easier. A way to permanently arrange the bits is required by both methods, eh? No difference there.

So you could toss literally anything in the "mass mulcher" and produce pure gold. The only difference would be efficiency.

>The amount of "pure energy" required per Kilo of matter is staggering.
>Breaking down matter to energy is a million atomic bombs worth of power, and some matter (mass) would be lost in the process.

So I figure a "half-way" solution would be best. You could still (in theory) do it the Star Trek way too.

Ripping matter down to energy and back to matter might prove inefficient: perhaps matter could be more easily "transformed" into similar stuff? Thus to make a desk? You toss some sawdust, woodchips and a few chemicals into the "printer". Some brass for the knobs, some metal for the hinges...

That would be far less efficient because it would require sufficient supply of suitable materials everywhere all the time. You'd also need to spend energy to break down the materials and more energy to reform them. How would it work, anyway? Nanobots working on a molecular scale?

This has already changed invention.
If your object is compatible with required wall thicknesses and is under 6 cubic inches or so, you can get pieces for mockup or substitution in hours rather than weeks.

Medical 3d printing already went into experimental application this year.

Dude: Stop listening to doom-gloomers. Really.
Actual statistic show the planet is becoming more passive the more educated and aware people are of the world outside of their own little corners.
My own opinion is "$1M in schools and internet is more devastating than $1B in military solution."

As long as evil exists these types of technologies will never be used for the good of the many.

This probably will change humanity for the better I hope. Of course with all things there's the ability for this to be abused to empower evil people but with that said. The applications of th is could be endless. This could literally create a utopia. Everyone has everything they would ever need. No need for economics as they currently stand. Interesting.
