Apis cor had some dealing with Samsung I remember. To me, they felt almost like marketing shop for their partners than a genuine engineering company.
When I voiced something about their engineering during an event, they weren't really able to reply with anything other than recital of their marketing.
IMHO, in its current iteration, 3d printed building are completely nonviable commercially.
The main point of 3d is to expensive, and error prone manual labour with a single pass automated process. 3D printed buildings as of now require more labour, more operations, and more materials than most conventional building techniques.
If we are still thinking of a house that has hidden wires in the walls and plumbing that is hidden in walls.... Then yes, printed homes as they are currently are not going to work.
If we embrace exposed conduit, exposed ducting and exposed plumbing lines, printed homes could be an order of magnitude cheaper.
What about getting a house with conduits for hvac, electric, and plumbing, and still get it cheaper than 3d?
Construction technologies to make lowrise housing super duper cheap are already here: panels, lgsf, large prefabs, light concretes
And for really tall highrises, they are already coming within 50-40% of their materials costs in Asian countries. So for them, it will make no difference even in the most optimistic case.
You can't do much physically about price of steel and cement, other than finding ways to use less of them.
