Ok so this is as off topic as it gets but. What if you built an entire house out of 1 single seamless mold using super tough polymer and super thick walls. Granted it would be expensive but it would be a super house. You could even build it as a large sphere with half above ground and half under ground if you wanted super resiliance but probably a capsule shape or a blimp liek shape with a slight arc all the way along the length with half above ground and half under would be best for a family or what not. The strongest earthquake ever recorded wouldn't phase this thing and it could potentially last idk hundreds of years before getting worn out, some polymers are amazingly tough, like the stuff they make 55gallon drums out of, imagine if that was a foot thick. Hell it would practically already be a boat, attach a rudder and a sale. It would be COMPLETELY air tight, you could place it in the middle of the amazon jungle and not have a bug problem. I bet it would even be partially bullet proof.

so someone tell me why this isnt done please. Would it just cost like literally a million dollars to make a single house? To heavy to move to location? No one cares about passing a legacy on to their children and then grand children and great grand children ect?

Plastic is more expensive than you might think.

Yes, such a home would cost in the millions at first, but even if mass-produced it would still be an incredibly expensive method.

On the same vein, if we know so much about food, vitamins, antioxidants and all that stuff, how come no one company simply produces a superfood that is perfect for humans? We could eat nothing but that superfood for a month, getting super nutrition, losing fat etc. Heck, maybe eat nothing but that every other day? Then we'd never have cancer or pimples or anything...

Point is, if the market is there it can happen. If not, it won't.

I don't think there's a market for multi-million dollar plastic homes, when fiberglass yachts are already a thing - and they're mobile too.

No need for polymer, someone's already found out how to make some pretty fast concrete, much cheaper too.

More interesting to me is the idea of printing buildings. Imagine a really large 3D printer that you can set up and feed in the design files, and it will build it.

It'd prolly give you cancer... living inside of one...

That printer would cost an incredible amount of money.

Hemp houses are more environment friendly, they have a negative carbon footprint and strengthen over time.

Maybe not. You could have a little one that just walks along the ground, printing as it goes, transitioning to walking on top of the walls once they're high enough.

Ooh, nice catch.

If a 3Doodler (http://www.wired.com/design/2013/02/3doodler) only costs $75, imagine mounting a few hundred of them on little wheels to drive around behind each other in series according to a program. Since those things dry so fast, what shape couldn't you build this way?

Imagine feeding this printer concrete and water etc., set a track for it to follow for the perimeter, and have it go to town.

It could even work with local materials, making concrete out of local soil. (and by local, I mean what used to be where your basement/foundation is now)

True, or even adobe huts etc. could probably even program it to "print" pieces of straw/hay for roofing.

I'd prefer clay tiles to thatching, myself. save the hay for the walls. ;)

Neat.

Now, imagine if that were a quadcopter....
