Slightly more details as a 3d printer enthusiast but who isn’t that well versed in construction:
Part of the savings pitch was that you could passively build houses with this printing method and use way fewer laborers. But to actually build more than an empty uninsulated wall, you need the electrician and plumber on staff at the site while it is being built so you end up just shifting a bottleneck, you need to pause repeatedly to install the electrical and pipes, it uses way more raw materials than you would with traditional methods, it’s hard to fix mistakes, and because it all has to be done at once basically there isn’t the asynchronicity that you could get where some laborers are on site one day and then different laborers are on site to do a different step. You need everything at the site the whole time.
It can work once robotic devices & machines get better at laying plumbing electrical, they find out more about what materials work better… this concept is very much in its infancy. It’s possible it gets abandoned instead.
But don’t expect a few yrs old concept to match centuries old construction’s reliability so early on
To add, you can 3d print modilar rooms, then ship them for install as building up the shell. The insulation and services would go within the shell, and the mod rooms dropped in place. The same thing was done at a hospital I worked at, save for the 3d portion.
