Looking at the picture on that article. I have seen people conventional frame a house that size in 2 days. So basically as fast. The thing with these 3d printed houses is it does nothing about the finishing work. That is where most the time is spent in construction. Those floors, doors, trim, electrical, plumbing, the painted ceiling, the roof, flashing windows and doors, the landscaping ect... in that 3d printed house took much longer than 18 hours. Framing is one the fastest stages in building a house. So you just make walls slightly faster it's not going to really speed up building a house overall. Like sure in these in pictures they forgo siding and drywall. But I will tell you inside the texture of that wall is going to collect dirt and dust overtime, and not everyone is gonna want a bumpy wall like that in every room. So avoiding some interior finish work like dry walling is not a given. Overall this does not speed up construction that much.
