3D printing for all

If you are depressed about the economic state of the world, one way to cheer yourself up is to google things like "fracking" or "natural gas". Another is to try "3D printing". That was how I found my way to this piece, about a company which has started selling 3D printers to … people. From what I can make out, each printer now costs something like two thousand dollars, more or less, depending on whether you want it ready to roll or are willing to assemble it yourself.

I can think of three things, right away, that are bound to be true about such "printers". They will get cleverer. They will get cheaper. They will get smaller.

Currently, these gizmos seem to resemble those very early personal computers, circa 1975 (as I remember it). There are no very obvious things you can do with them, but despite that, they just reek of the future. Learn about them, and the next four decades of world technological history will be yours to surf at will, in ways that are impossible to know the details of but which are bound to be huge.

In due course, 3D printers may become no rarer than the 2D printers like the one I have on my desk are now. The first laser printer I blagged may way to using cost (someone else) around two thousand quid. My current one cost (me) about eighty quid, and is much better, not least because it is so much smaller. Presumably similar progress will occur with 3D printers.

I wonder what such machines will do to the world?
