How long will it take to 3D print a house?

The time necessary to print a house will depend on a series of factors, starting with the materials: using rapid set cement (which does not interest us although our BigDelta is able to print it) times are significantly shorter and it would take only a few hours to build walls that are several meters tall. If, instead, we choose locally sourced materials, such as clay and raw soil, it is necessary to let the material dry out before depositing more of it, in order to keep it from collapsing. For this reason, if we use natural raw materials without additives, a lot depends on the climate. In a dry and mild environment soil dries up much faster. We do not have a precise answer to this question. It could take a day as well as week. Much depends on the in-field variables.
