NYT on 3D printing

The NYT covers 3D printing, from the Makerbot and textile printers to custom prosthetic limbs to a mighty house-printer:
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. Advocates of the technology say that by doing away with manual labor, 3-D printing could revamp the economics of manufacturing and revive American industry as creativity and ingenuity replace labor costs as the main concern around a variety of goods.

"There is nothing to be gained by going overseas except for higher shipping charges," Mr. Summit said.
