In the year 2100, how much of construction will remain in human hands? Precious little, I would think.

Pluses include much cheaper structures that are much quicker to completion, home costs being lower and personalized architecture being readily available. The chief minus is, of course, the number of jobs lost. If just the construction and trucking industries were lost to printing and automation, that would leave a huge gulf in the U.S. Labor market.

From Andrew Torchia of Reuters:

DUBAI (Reuters) – Dubai said it would construct a small office building using a 3D printer for the first time, in a drive to develop technology that would cut costs and save time as the city grows.

3D printing, which uses a printer to make three-dimensional objects from a digital design, is taking off in manufacturing industries around the world but has so far been used little in construction.

Dubai’s one-storey prototype building, with about 2,000 square feet (185 square meters) of floor space, will be printed layer-by-layer using a 20-foot tall printer, Mohamed Al Gergawi, the United Arab Emirates Minister of Cabinet Affairs, said on Tuesday.

It would then be assembled on site within a few weeks. Interior furniture and structural components would also be built through 3D printing with reinforced concrete, gypsum reinforced with glass fiber, and plastic.•
