3D printing a house

See Contour Crafting: Automated Construction (via Peak Energy)

Behrokh Khoshnevis, an engineering professor at the University of Southern California, is developing a scaled up version of 3D printing that he has dubbed ‘contour crafting’. He hopes that it may one day be able to alleviate housing shortages in the world due to its speed (he estimates that an entire house can be constructed in about 20 hours) and the reduced costs associated with its use.

This is a clear cut example of a solution that, as Khoshnevis says, “benefits from advanced technology”. It tackles the complicated problem of affordable and abundant housing head on, though it would appear to do nothing about addressing the larger problem of poverty. Opponents to the technological approach might argue that the real problem has to do with the structure of societal and financial systems. Though a cheap and sturdy home might be a step up from the slums, if the underlying problems of income inequality and resource allocation still remain, they will surface in other ways. One only needs to look towards housing projects in American cities and elsewhere to know that giving someone a roof over their head doesn’t necessarily free them from a life of poverty and crime.

Khoshnevis mentions another potential use, which is using contour crafting to construct buildings in situations where previous construction methods could not work (such as in building a moon base). This strikes me as a better use of the technology, since the problems it solves here are more straightforward and direct, rather than being simply one small subset of larger socio-economic issues.
