3D-printed homes are far stronger than most people realize

    1. I don’t question how strong they are. I question how pricey it is to build. They were supposed to be cheaper than traditional. Are they yet?

      People in the comment acting like houses around the world outsides of the USA aren’t made of cardboard and wood but out of bricks, stones, concretes, etc and we don’t have a problem adding rooms, fixing electricity or plombing etc… the problem isn’t how hard the wall is really, it’s more about the shape and structural integrity overall but people act like a wall made of sturdier elements than cardboard is “unbreakable” and you can’t fix your house down the road lmao

      But it can’t shift unlike bricks or timber when the water table drops over summer. . .

      It shall be very interesting to see how it plays out.

      Who thought that 6 inches of pure concrete was going to be weak?
      I just think the walls look stupid.

    5. Strong against a hammer, sure. But it’s still concrete: without rebar it’s only strong in compression, not in tension. Can’t build anything like this in hurricane or tornado regions, or even really anywhere that gets strong storms at all, it would tear apart like putty.

      Every time I see stuff like this showing off how strong it is by smacking it with a hammer…. that’s not what houses are dealing with. The real challenge is longtime weight. The forces in play there require a completely different approach than impact absorption

    7. Query – how do these things perform in earthquake zones? Don’t you have to reinforce the walls with something like rebar or wire mesh? How is that 3D printed?

      The problem with them isn’t strength- it’s that they use 5x as much concrete, and as a result are 2-3x more expensive to build.

    9. Being “3d printed” doesnt make it weaker or stronger. Its what the material is.  You could 3d print in pooh
