3d printed concrete houses exist. Why can't you 3d print a house? Not the best metaphor lol
You can certainly 3D print a building, but can you really 3D print a house? Can it 3d print doors and windows that can open and close and be locked? Can it 3D print the plumbing and wiring and have it be safe and functional? Can it 3D print the foundation? What about bathroom fixtures, kitchen cabinets, and things like carpet?
It's actually not a bad metaphor. You can use a 3D printer to help with building a house, and to 3D print some of fixtures and bits and pieces that go into the house. Using a 3D printer would automate a fair amount of the manual labor that goes into building a house today (at least how it is done in the US). But you're still going to need people who know what they are doing put it all together to transform the building to a functional home. We're still a fair ways away from just being able to 3D print a house, just like we're fair ways away from having a LLM write a large, complex piece of software.
Exactly this.
No they aren't. With enough setup and very unique and expensive equipment, you can pour shitty concrete walls that will be way more expensive and worse than if you did it normally. That will give you 20% of the house, at best. 20% of not very good of a house.
You don't like glass windows? Air conditioning? A door?
