"3-D Printing Spurs a Manufacturing Revolution
By ASHLEE VANCE
SAN FRANCISCO Businesses in the South Park
district of San Francisco generally sell either
Web technology or sandwiches and burritos.
Bespoke Innovations plans to sell designer body parts.
The company is using advances in a technology
known as 3-D printing to create prosthetic limb
casings wrapped in embroidered leather,
shimmering metal or whatever else someone might want. . . .
A California start-up is even working on building
houses. Its printer, which would fit on a
tractor-trailer, would use patterns delivered by
computer, squirt out layers of special concrete
and build entire walls that could be connected to form the basis of a house.
It is manufacturing with a mouse click instead of
hammers, nails and, well, workers. . . ."
