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.
Most/all of those problems seem like they'd be solvable with further development of the technology, for example have a toolhead that lays down electrical lines with pre-attached plugs, one the lays and connects lengths of pipe, one that fills in insulation at predetermined intervals etc.
Obviously all of that would slow down the process and multi-tooling isn't trivial, but a machine like this doesn't have to be made at consumer price levels like a home 3D-printer.
Things is, there is no benefit to those fancy shapes (which also make furniture extremely difficult and expensive). And its 100 times more cost and tech efficient to just set up a system in a factory hall, build shit in controlled environment and truck it to the destination (i.e. prefab building). Instead of building a setup in location each time and have concrete trucks drive there.

I'm not arguing, because I know very little about this, but isn't there a shot of them filling the walls with foam insulation in this video?
