The Crane WASP, also known as "the infinity 3D printer," uses locally sourced clay, mud or cement to 3D-print affordable homes. It can even use agricultural waste as aggregate. The system is now being used to build much-needed housing in Colombia.
This is the UN, remember. They aren’t worried about people with options. The question is if this thing is actually easier and cheaper than local labour.
I’m no luddite, if it makes sense to automate some menial task we should. Let’s do the napkin math.
It says it costs 180,000USD. A labourer in rural Columbia might cost 1USD per man-hour. If we assume it replaces two workers, and produces a house generously 3 times as good, that’s your investment back in 30,000 hours, or ~3.5 years.
Actually, that’s decent. I guess I was expecting it to cost millions. If you make less generous assumptions, you get a less generous result, but they have a shot.
It uses soil, without firing it sounds like they’re just expensive mud huts?
Better than nothing!

Another good point- lets fix poverty by replacing local labor with a 3d printing machine!
