"Aaaahhh Mom, are we having zymoveal again?" That was the complaint of a jaded kid in one of Isaac Asimov's best science fiction novels. The food item was imitation beef, cranked out in the underground city's big yeast vats.

One day a 3D printer will be both able to and programmed to print out several 3D printers each being identical to itself and each one of those 3D printers will print out several more identical 3D printers and so on and on forever.

Originally posted by humyThe biggest constraint as it currently stands is that 3D printers need materials to print with. So until they develop the ability to seek out raw material on their own, uncontrolled reproduction just cannot happen. And lets not forget the power supply, but I guess solar powered ones would resolve that.

I could currently afford a 3D printer, but have not bought one because the cost of the supplies is still too high. Incidentally the same argument explains why I haven't bought an inkjet printer.

Modern inkjet printing is one big rip-off.
