"One can see the free software movement as a precusor for a "free hardware" or "free wetware" movement--one that will provide free libraries of designs for biological or nanotechnological products that replicators can be programmed to churn out."
- Charles Stross

  Send a copy of a three-dimensional object to a distant place.  

If you think that this sounds unlikely, you should understand that something like this already exists, and was in use for at least a few years before being described in the novel. It's called stereolithography, and it is used to create a three-dimensional plastic model from a three-dimensional computer-aided design (CAD) drawing. All you need is your CAD model and

  • A tank full of liquid photopolymer
  • a perforated platform in the tank (which moves up and down)
  • an ultraviolet laser (which solidifies the photopolymer at particular points)
  • and a computer that drives the laser and the platform.
Sound expensive? Read on.


"Everything the name implies," says Klaus, "and considerably less."

"What's that supposed to mean?"

"Nanofax AG offers a technology that digitally reproduces objects, physically, at a distance. Within certain rather large limitations, of course. A child's doll, placed in a Lucky Dragon Nanofax unit in London, will be reproduced in the Lucky Dragon Nanofax unit in New York-"

Stereolithography (or a nanofax machine) is not likely to show up at your local convenience store anytime soon. The machines cost about $250,000 and the polymer is about $800 per gallon.

Keep in mind, of course, that computers no more powerful than a $5 calculator once cost millions of dollars, and random access memory (RAM) that I once paid $600 for now costs one-half of one cent.

The commentary for dustmice discusses a very small robot that is partly fabricated using stereolithography.
