3D-Printed House Constructed On-Site In One Day (treehugger.com)

Heffenfeffer writes: Russian company Apis Cor has manufactured a 3D printed concrete house on-site in 24 hours in Stupino Town, Russia. Using a tower crane-shaped concrete extruder that can rotate 360 degrees, the 38 square meter (408.88 square foot) rotor-shaped home walls were constructed in one day. Voids left in the manufacturing process were filled by hand, installing windows, doors, and adding polyurethane and fiber insulation to the hollow concrete walls. The roof was also constructed by hand using polymer membranes, welded together using hot air and special equipment. Total construction costs were $10,134 (USD), approximately $266.66 per square meter ($24.78 per square foot). They also constructed a temporary protective heated tent to surround the house as they constructed the house during winter. Though the printer can be used at temperatures down to -35C, concrete has to be at least +5C to cure. Further reading: Designboom Magazine

Insulation handling gear is pretty light, so it'll be easy to counterbalance, and can traverse in and out quickly. It should also spray in much faster than concrete, so the computer would just keep track of which voids still need insulation and are cured enough to accept it.

      Rebar will be much harder. I'm thinking of a rotary multi-head where the subarms are able to swing together and apart. As they come to a piece of rebar, one arm will approach it from the back and the other from the front. They'll come together briefly to make a continuous pour, then the back arm will swing away and around to get ready for the next piece. I don't see any reason why another arm can't place and weld the rebar, and then spray epoxy on later passes. The question will be time. The welds need to cool before the epoxy spray, and the epoxy needs to cure before the concrete, and the concrete needs to set before the insulation can be sprayed.

    ... Constructed On-Site In One Day ...

    Going from finished foundations to medium-size house in one summery day has been possible for 30-something years. It about logistics and quick-set cement, which no-one uses. A small wooden house with pre-fab frames can be done in a day also. The real problem is that there's no way to pre-fab brick, the most popular building material for houses.

    The construction industry has embraced pre-fab frames and walls poured on-site but not pre-fab walls. There was an episode of 'Grand designs' where the 2-story house was constructed from prefabricated walls and floors, complete with plumbing, wiring and paint. If the dream of 'The Jetsons' is to be realized, with high-rise apartment buildings completed in a week, this will be the way forward.

    But can I really build a home for $10,000? Aside from the sewer and electric and what not and the fact that it's kind of small. And of course the land.

    I didn't read this article, but I read another one which bragged that they could do this in other shapes and sizes.

    I don't need a big home but I didn't see what the bathroom looks like in this place and that kitchen looks horrible.

    I've got more home than I need right now, but sometimes it's really nice to have that much room.

      You can do it with a shipping container. Prices range from about $2k to $5k delivered depending on size and where you want it. You cut window holes out with a plasma cutter. Finishing the inside is non-structural, so it can be done by a monkey. Frame it in 2x2s and slap some 1" foam up inside. Or surround the outside with straw bales. Either way you get a structure which is proof against anything short of a tornado. If you want it to withstand a landslide, orient a long end towards the potential source of the sliding land.

  15. Nice printer size by John.Banister · · Score: 2

    It looks like a good size printer to rent for DIY projects. I'd like to see a printer like this using cellular lightweight concrete to print in place insulating concrete forms. Then, it would be very easy to make ICF walls that are any shape at all. Seeing so many houses with square corners just looks depressing to me.

    There are plenty of novel and exciting uses for 3D printing. This is not one of them. Why? We've had concrete tilt-up construction for a long time now. So they do it with a 3D printer instead of molds, it's still concrete. It will still have problems in seismically active areas.

      Foam blocking is how they do it in every other case of real construction where they pour concrete, so I assume here too. Of course, like most of this project, that took actual humans to accomplish.
