This here is low cost and affordable: https://en.m.wikipedia.org/wiki/Plattenbau https://en.m.wikipedia.org/wiki/Plattenbau Almost 100 years ago Germans discovered the way of cheap building. The first houses are still used according recent documentary. This 3D printing might be novel, but basically they move their factory each time for a new house while Plattenbau factory must be installed once. Plus Plattenbau has canals for cables and already installed windows and doors. Plus Plattenbau can be a high building. I live in one from 1965, it’s really shitty. Insulation between concrete layers is gone, you can hear TV of the neighbors and it’s cold in winter.
