Your 3d printer doesn’t have other utilities to accommodate. The printing is basically just the walls. Every other utility (Power, water, sanitary, HVAC, foundations, windows, doors, metal fabrications, networking etc) are all still done by people, all made with options made by other manufacturers.
Your printer also uses quick setting thermoplastic, not a concrete slurry that needs to set over the course of days instead of fractions of a second.
This and typical FDM printing are related, but truths about printing out a plastic trinket don’t necessarily translate to large concrete structures.
I ended up falling into using a surface for my travel and it’s been surprisingly good. I have surface pro 7+, and it’s small enough to use on an airplane seat, has good battery life, a great screen, and can do some limited gaming. With an upgraded drive (1TB for $100) for movies and low end games it’s a great little computer. They also run for 200-400 dollars on eBay.
