I have read interesting articles and reports, watched videos of “printed” structures, mostly as experiments as part of research at universities. The material used in producing these is usually a specialized concrete mixture that flows easily, yet has body and gains reasonable strength when cured.
I originally saw the video below on curbed.com at this link. I’ve included the video from YouTube due to its interesting nature, with the realization that this is a corporate film produced to promote a product, and therefore, may have a bit of puffery. Obviously, most people would not be able to rush out and order one of their own, but maybe sometime in the future such technology might be available.
As for now, I can imagine that the technologies displayed below would be a useful hybridization of current building techniques. For example, suppose the foundation or basement of a house were “printed” instead of laid out in block or poured with concrete forms. For that matter, anything that could be produced with this technique such as steps or a porch would save tremendous amounts of time and labor.
This is just a preliminary. I plan on a couple of articles on alternative building techniques such as these for the near future, along with another article on unusual prefab buildings.
Here is the video:
