Here’s to hoping this reduces the amount of trees we have to clear for home building and makes increasing the supply of affordable homes easier.

Concrete isn't sustainable - trees are.

The cement industry is one of the biggest producers of CO2 - trees capture CO2.

Supply issue has nothing to do with the raw materials. This is not the way.

Ok I agree on the trees.

But if 3D printing can make homes easier to build and cheaper then perhaps we can build more and help increase supply lowering housing prices.
