Mmmmmm 3D printed houses. I would slury the earth on site and extrude clay, also thinking about a foam extruder that could print cacuoons for the unhoused with an embedded solar panel. Good to see progress in standard construction.

I can't tell much from the video, but are they able to print pipes, wires, doors? They also mentioned they 'finished it off' with shingles and such. I started thinking about buying some land and building some kit A frame home for glamping, and it seems like the grading, foundation, plumbing, windows, interior, etc are all a bigger cost than the walls. I never realized this before looking into it.

  Nope, they didn’t print the pipes, wires, and doors as loosely alluded to here: “Andersen said the actual printing time for the walls took about 48 hours, part of an overall eight-day process to build the entire home.” It strikes me that the part of the house building this aims to improve is one of the cheaper parts of house building. I suppose it ultimately saves on time, although with enough carpenters, they could get something done in far less than 8 days.

  From a different site (https://3dprintingindustry.com/news/sq4d-3d-prints-1900-sq-ft-home-in-48-hours-167141/ https://3dprintingindustry.com/news/sq4d-3d-prints-1900-sq-f...) it seems to me like they print the framing/sheathing/siding with rough openings for doors and windows, but not much else. It’s still thin on details but I think they rely on standard processes for roofing, wiring, plumbing, HVAC, etc. It’s a bit disappointing because I feel you could just as well pour concrete foundations and walls and achieve the same.

I don’t understand the economics of it. They must... some business plan must certainly demonstrate the wisdom of this. But I just don’t grok it... a pre-fab can be trucked in and thrown together in a couple days, plumbing, electrical, and all.

$212 per sqft is pretty average (considering the price of the land). I am not sure how much this actually saved. The biggest benefit is that you need less workers on site. If they had built a duplex or triplex it would have been a net gain though.
