3D printed houses are coming and you could live in one from next year

I suspect when the technology is ready they’ll incorporte alternative reinforcing materials such as something like nylon mesh or even kevlar if needed. Something that can be co-extruded at the time of construction. I like the printed concrete idea myself, it’s really a small step from pumped concrete work that’s been done for years.

3-D Printer Ping!

Yep, I’ve seen them. But my first thought was what 2DV thought...The town of Bedrock.

Concrete has a terrible R-value.

Yes, but it can be hollowed out for insulation:

Don’t know where to start from your statement.

I can find you an open plot of land to build a house just about anywhere in the United States.

Where do you want to build?

Concrete has a terrible R-value.

These oddly shaped structures are not easy to insulate but normally shaped structures can be insulated with exterior foam ,,, keeps the thermal mass inside the envelope.. You can also just use cement with chopped polyester strands for added strength. The “all one piece” printed house will be plenty strong compared to cement block...

That would be good. Concrete construction has a lot of good features- fire resistance being something we could sure use out here. And no termites.

I don’t see any rebar in the pics but maybe they can integrate it. Not sure.

You definitely have something there.

Next we will be informed that the construction material used is human waste and a cow urine binder.

I recall reading a science fiction story, years ago, which had houses being formed in this way. The term "3D Printing" hadn't been coined yet, but the idea was there.
