Futurology

Thanks! Very interesting.

I suppose you could print the plumbing directly into a building, but that has obvious maintenance risks.

because almost always if you have the land to build a shack, the cost of the shack isn’t going to keep you on the street.

That's also thought-provoking. For scavenged sheet metal screwed together I'm guessing it's always true. Rammed earth is a bit more work, but I don't know how it compares to cinder block both performance and price-wise.

In any case, a 3D printer imported from the expensive West will take a long time to earn itself back.
