Never saw the point of these 3D printed houses. They have been announcing them for almost 2 decades and all that for what?
3D printers can't apply rebar, which is absolutely fundamental for concrete under flection. Concrete 3D printers will never print slabs. They can't print foundations, those must still be excavated by a crew.
And even if you solve that what, you solved like 20% of a construction project and literally the part that goes up the quickest, well done, then you still need to do plumbing, doors and windows, electrical, finishes and a whole fuckton of other shit.
3D printed walls suck at thermal isolation too, even if you place some kind of thermal isolator in the middle of the 3D printed wall you will end up by design with a crapload of thermal bridges everywhere anyways.
