    having the potential to be significantly cheaper and faster than standard construction

    I don’t see how this can ever be true. The only material that can come out of the printer is the concrete for the walls. The walls then have to be reinforced (because concrete is only good under compression), insulated, finished, and then have windows, doors, wiring and plumbing installed… all of which is still just manual labor. The walls aren’t even the expensive part of homebuilding.

      It depends on what you’re building. If you want a normal rectangular house, 3D printing will be incredibly inefficient and pointless compared to traditional framing techniques.

      On the other hand, if you want curved walls, traditional framing becomes incredibly complex and expensive, whereas 3D printing takes exactly the same materials and labour regardless.

      I think 3D printing an entire house is just a gimmick, but it will still be an incredibly useful tool, even if only used for simple things like making rounded foundation pads or retaining walls that follow the landscape or curved hallways connecting modular buildings.

        How many people actually want curved walls though?

        You need curved couches, shelves, cabinets, windows and picture frames then too.

        Geodesic domes housing is even faster to build, but it turns out not very many people like living in circular (or spherical) houses.

          How many people actually want curved walls though?

          People who hire fancy architects. Not people who have to work for a living.
