Printed concrete houses are built fast and if done right will be strong. Two or more stories will require some I beams I believe. They can be built in any style, you can customize them, add a garage or two etc. The rough surface can be smoothed flat or drywall put over it. The reason multiple stories will be a problem is that the concrete is poured without any voids in it as you will find with concrete blocks. This makes it heavier and denser. Even block homes I've seen built usually have the second floor made of wood. At 3 or more stories the weight of the upper floors will be a problem unless you support them.
Electrical wiring and plumbing is a bit more complicated. Little tasks like attaching wires, installing receptacles, light fixtures, etc requires manual dexterity and each job is slightly different making it hard to automate. Plumbing too has these problems. Some construction jobs can be automated but not all, not yet.

Woah there, I was told that work was the only thing that made life worth living. If everyone didn't have a job, they would waste away and die. Now you tell me people don't really like to work, they will do it for enough money but not manual labor? Would you be happy if you got a paycheck and didn't have to work? Would you be able to find things to do? Rich people seem happy and they don't have to work
