I assume the row house design is due to the gantry that the 3D printer sits on.
- Kirby64 2y agoThere’s gaps inbetween the walls and they add insulation as far as I know. Concrete by itself isn’t very insulative even with an air gap.

- stufffer 2y agoI 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.
- binary_slinger 2y agoIf electrical and plumbing needs rework can the walls be safely cut without to much structural damage? How would repairing the cuts work?
- stufffer 2y agoIf 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.
- rawgabbit 2y agoThanks. I read that PERI printed a house in Houston with an extremely large U shape gantry. The house is waiting to be finished though. https://www.chron.com/news/houston-texas/article/houston-3d-printed-home-19368865.php https://www.chron.com/news/houston-texas/article/houston-3d-...
