How come America even though richer lags behind Asian and developing nations that leapfrog in tech? This list of excuses is depressing: https://www.probuilder.

  If the idea is that of building a one storey circular shed roughly 5 meters in diameter (which is what essentially current 3d building is capable of) we might sit down and compare costs against other building techniques (and I strongly doubt that the 30-40% savings touted is achievable, particularly in countries where the workers wages are not particularly high). If instead the idea is to use 3d printing to build actual homes, the technology is simply not there to do much more than erecting the (not insulated) walls, that represent (of course it depends on countries and local building standards) a small percentage of the building costs, likely less than 10%.

    It’s difficult to move things along in America due to govt and labour unions. Things that are supposed to raise quality of life for the masses.

  I don't see in rebar in the construction process. It will crack and fall apart in a short time.

    Of course, there is rebar in 3D printed constructions. They also use proprietary concrete/cement.

  America has more developed systems so there’s less need for innovation. If you think the US is bad Japan still uses fax machines in common usage
