  1. A few comments: 1. I suspect they are showing the walls are hollow and will be filled with insulation later. 2. The external pattern of lines formed by the printing process is interesting, but not necessary. They could finish with standard gunnite and give a flat textured surface. 3. Obviously the interior walls are cement. 4. The strength of the building needs to be proved.
