I toured their factory one time and saw some demo print structures. The walls were double layered, spaced out 8-12? Inches. The bead would flip from inner to outer to give lateral support. Inside the walls were insulation. Plumping in Texas is embedded in the foundation but I believe electrical wiring was in the walls as well.

The printing gantry only could move in one axis so building width is limited.

Thanks. I read that PERI printed a house in Houston with an extremely large U shape gantry. The house is waiting to be finished though.

If electrical and plumbing needs rework can the walls be safely cut without to much structural damage? How would repairing the cuts work?

If one needed to re-run electrical wires, I assume you could drill holes and pull new cabling through the walls into the attic space.

If you had to re-run water or sewer, you have to jack hammer the foundation. But that is the same a wood frame homes.
