In spite of the demonstration videos of robots running and jumping and carrying boxes and slowly sorting packages, none of them are anywhere close to being ready to handle construction jobs, or most manufacturing jobs. And, they can't design or make the machines that automate the processes.
It's a billionaire's dream that this is happening now, it's not. One of the major hurdles is power consumption, as we're all seeing while they build out these "data centers". Robots and computers cannot match the efficiency and self-sufficiency of a human. In a picture:
Don't they have "3D Printed" houses?
I think the issue is, we are thinking of robots carrying boards and hammering nails etc.
Even not 3D printing you cpuld have a factory that cranks out walls and some sort of automated system that assembles them on site.
IIRC “3D Printed” houses are falling apart due to lamination issues. That said, I think it's a solvable problem, though it will take awhile to sort out the issues. Modular systems also show a lot of promise for mass production, potentially even of higher quality, and likely amenable to robotic assembly if carefully designed for it, but we know it'll just be a profit seeking race to the bottom. Those construction jobs are safe for at least a decade, likely more.
You'd probably have to invent a new type of concrete first. You can add resin binders to concrete to make wet concrete somewhat stick to drying concrete but it doesn't work very well. The drying concrete tends to pull the moisture from the wet concrete which ends up interfering with the curing of both sides.
The main issue with 3d printing concrete is more of an inherent issue with how homes settle over time. Unless you are building on bedrock or you're driving a massive amounts of piles for the foundation, structures will move and settle over time. This is why brick and mortar have been around for such a long time, the mortar gives the bricks enough flexibility to accommodate movement.
Concrete lacks this flexibility and will crack and crumble apart unless you reinforce it with rebar. Rebar gives concrete tensile strength, distributes weight across the whole structure, and holds cracked pieces together. So really any 3d printed home that isn't reinforced somehow wont last very long.
