“ICON prints the homes on site, using its Vulcan construction system, which spits out a “proprietary extrudable concrete”...

Calling it a 3D printed house is an exaggeration. Typical for the press. It’s an extruded concrete foundation, which I would have to wonder about its cost-effectiveness compared to the typical form-built foundation. This “3-D” is just hype.
The first floor walls are also extruded.
This is not an exaggeration. The lower level goes down with very little labor and it goes quickly. Eventually they will certify two story construction, perhaps even roofing. Imagine building a house with three people, someone to run the printer, an electrician and a plumber. Concrete is cheap.
Thank you for your perspective. It helps me make heads or tails of this movement.
