This is true, but for a regular bungalow, 3 bedroom, 2 bathroom house on one floor,
If you 3d print,
You make a slab foundation, let’s call that week 1
you pay one truck to haul the printer there, and setup, calibrate etc, 3 days,
Pour the house, with say 5 cement trucks worth of haul, we will er on caution and say 4 days
3 days to put up rafters, sheath the roof and shingle. (With a decent crew) and have a stucco guy smooth the exterior.
In three weeks your exterior is done and you’ve moved on to interior and exterior finishing.
After a month and a half you’ve built a house with virtually no over head. No warehouse or factory, no rent, just materials and labor cost. This simplifies it of course, but I can totally get the appeal.
It’s like a construction company version of a food truck.
Mind you for anything larger yes I would want more substantial slabs etc, so for larger projects that totally makes sense. For economical affordable housing this country desperately needs? This is a great way to achieve that
Housing costs are on a runaway. A bungalow just like described just sold for 500,000 next to my inlaws in the middle of nowhere with no real yard or anything. Investment properties charging more then a mortgage for rent. Hell there’s tent cities popping all over the nation because people can’t afford the system we are building up And god help you if you want to buy your first house as a young couple with kids without help
