think about it, you can't add the "spacers and diagonals" after they need to be done in real time, my guess electrical and plumbing would be the same.


I am no builder and know nothing about cement of any kind. but I would guess

1) you could always have multiple arms going at once each printing its own section.

2) it might not need to be totally dried but the house goes up in rows (round and round and round again in inches until you have the full height. Obviously the previous row needs to be dried enough so that that it can support the current row and even more dry and solid before it adds the next row...

Did you see the second video? at between 3:50 and 4:00 they discuss it. It is a vinyl paint that they can apply immediately after the printing ends.

agree with you, not only that but also a step by step guide. On the other hand you can still buy Lego's (or other similar blocks) that are not kit specific and some that come with multiple schematics for different stuff.

lol

So they squirt out enough cement in 24 hrs to make a round house and painted over a crappy looking finish. I let out a crappy looking round brown house watching that.

The Model T was the first car to roll off an assembly line. Compared some of the other cars at the time that were being hand built,the Model T looked like a turd with wheels on it. But the process was innovative and revolutionized manufacturing.

agree

plus

1) Round is much stronger, that is why windmills, lighthouses and traditional towers were round.

2) The round shape has the largest area for the smallest perimeter (biggest house for the least amount of walls)

3) if one looks at the video they can see that not all the walls are round (the interior bathroom wall? is flat). I am guessing the house was round due to the limited radius of the device and them wanting to say we can build a home that is 38 m^{2 (~400 square feet) in 24h (and let's not forget painting where corners add a lot of time)}

Round may give the most area for the smallest perimeter, but you end up with a lot of wasted space because almost all furniture, appliances, and other home furnishings are designed for rooms with 90 degree corners.

You can easily place and functionally use furniture that is more or less rectangular. This is not true for circular furniture. Imagine circular seating around a circular dinner table.

First I see this as a publicity stunt, it is all about the headline home built in 24h. Maybe it could be used to build emergency shelters (but then you probably want something less permanent) but for the most part people don't need to build a home in 24h. So what fits in it would be secondary

Second what you say is true only if the circle is small compared to the length of the object in it.

look at this pic

the triangle wastes a lot of space (white space between triangle and circle) , the decagon at the lower right has almost no wasted space. So (like any small place) it would all be about being smart (e.g. two love seats against the external wall would waste less space behind them then a sofa that fits 4)

I see this technology possibly being a factor in the future of home building. It could possibly reduce the cost and time to build a home if the machinery is inexpensive enough. Many construction workers would be without jobs if something like this became practical for builders. Believe me they would replace workers with robots now if robots were cost effective for building a framed house. I don't know if this will catch on, but if it does I think we will see a lot of them.

Split those circles into rooms. Usually wedge shaped rooms.

If we are talking this house, we know the rooms, the interior walls are "printed" at the same time as the external walls. It has a vestibule (entrance hall), washroom and open concept room that is used for everything else.





now if we are talking in general, I agree some people might over do it with the idea of "it is not the normal box so I don't want any walls that are 90^o


but they don't need to and you can have 90^o walls and rectangular rooms if you want
