What it doesn’t tell you is how the building industry will fight these by regulatory capture of city zoning laws, just as they fight tiny houses in so many places. Think of a small 3D-printed house as a slightly different kind of tiny house, and then look at the zoning wars and rules in their way.
From a libertarian perspective, one can be delighted and excited to see such technological progress to make more affordable housing. But from a view of the briarpatch of zoning laws that nimbys and builders have erected to block such progress, it’s easy to become cynical about how much, can actually be accomplished, at least in the regulatory-burdened US. I did notice that your linked article mentioned that the first 3D project they were reporting on would be in some as-yet-undisclosed Latin American country.
The technology is amazing. These 3D printed homes can provide more stable and safer homes in many of the third world countries. Too bad the US building industry will fight this because it replaces out a sizable portion of construction trade of frame building. Will be interesting to see how this affects the industry in the future.
