Even if it's not prefabricated - what is the advantage over concrete forms? This is similar to injection molding vs 3D printing, however concrete forms are much easier to construct than injection molds. We also have the issue of site prep, roofing, insulation, wiring, windows, doors, etc., all of which are not 3D printed. You could have a 3D printer handle millwork, decorations, inlays, embossings, and things like that, but for the giant blocky structures it doesn't do much.
