Future of construction process

[metoo6000]

Have you heard about Additive (a.k.a. rapid or layered) Manufacturing processes, e.g., 3D printing? If so, have you seen any research or practice use the processes for construction applications? There are few works exist and the below link shows one of them. This short video shows the present and future of innovative construction process. What do you think?

The technology sounds promising.

However, how strong would be buildings built like this? There are no steel bars...

This is a post-tensioned component using rebar. If you see the last few slides, you can actually see the post-tensioned rebars in the component. In addition, the used cementitious material is actually more than three times stronger than normal concrete in terms of compressive and flexural strengths.

Possibility is endless.

I do not have a civil eng'g background, but this looks pretty amazing.
