> It seemed slightly more trouble to do modifications than a cinder block wall, but the quality and strength was much higher. I went with low expectations but I was impressed.

So the electricians and plumbers would all come in after the wall was printed, and saw through it all? Sawing, adding and then filling it back in sounds like lots of work to me. With stick-frame, wiring and plumbing are still a significant cost, but the actual hole-making part would be a small proportion of it.
