As usual for "3d printed house" stories, there's no mention of reinforcement. Is this just unreinforced concrete?

  Or, you know, foundation.

  I'd guess maybe fiber reinforcing?

  Doesn't reinforced concrete have a lot of longevity problems? If the printing is limited to the walls, i.e no large suspended horizontal section, it seems better to stick to pure concrete from my non-expert understanding.

    The climate may require using corrosion resistant rebar; most non-corrosion failure modes would happen with unreinforced OPC.

Mostly near sources of (salt) water: put a roof on a house, and make sure you have slopes away from the structure, and it's not a large problem. Or, instead of metal/steal rebar, you can use composite rebar: * https://www.jlconline.com/how-to/foundations/composite-vs-standard-steel-rebar_o https://www.jlconline.com/how-to/foundations/composite-vs-st... There's also fiber-reinforced concrete (which may not always be a replacement for rebar): * https://en.wikipedia.org/wiki/Fiber-reinforced_concrete https://en.wikipedia.org/wiki/Fiber-reinforced_concrete
