3D Concrete Printing

This is an interesting image followed by a link to a video showing this concrete printer in action. Although it's a bit sloppy, I'm sure they could work on that a bit. I could easily see a machine like this printing a home sometime in the near future.....

That's not concrete. It's cement. Concrete has stone aggregate mixed in.

Could produce a better finish if they made a trowel fitting that soothed the sides of the extrusion as well as the top.

OME

duh... look like crap? :P
