Dan of Dan's Data has posted a look at the state of 3-D printing.  If you can afford one of the printers, you can have just about anything you can imagine.  Or if it works out like he is thinking, a trip to Kinko's or Office Depot may be a bit more interesting in the future.


"In The Beginning of "additive" 3D printing (as opposed to the old "subtractive" milling machines

that cut a shape out of a block of source material), there were stereolithography machines, that

UV-lasered a slowly growing resin prototype out of a bath of liquid, layer by layer. Now the big

news in general purpose 3D printing is a similar layered arrangement, but using a fusible powder

that gives more rapid printing with less fuss, and a more durable result. This is the same basic

idea as was used by MIT's original 3D printing machines, but those machines used cornflour or

plaster as the powder. Today's powder-printers (and their wire-fed competitors) can make objects

that don't, um, fall apart in the rain."
