China has a way with construction.

"using a proprietary 3D printer that uses a mixture of ground construction and industrial waste, such as glass and tailings, petrochemical refinery sludge and human waste.

Fixed it.

Layering looks crude and odd.

That could be fixed.

Concrete diluted with ground glass and industrial waste, and no rebar?

Oh well, There's 6 Billion Chinese, they won't miss a few hundred killed...

...around a base of quick-drying cement mixed with a special hardening agent.

Must've found a cheap substitute for Viagra.

Made with clean, reliable, non-toxic Chinese materials. What could go wrong?

Am not impressed.

They printed parts and then constructed buildings on-site with those parts. That is prefabrication which is done regularly in many different ways.

When a building is completely printed on-site they will have done something new.

It was bad enough when a lot of homes had to rip out all their contaminated Chinese drywall. Now you too can have a whole house made of material of unknown origin that may have embedded toxins. There is no way to certify such a house unless someone can certify the material it is printed from.
