A house 3D printed from raw earth
Yet another example of the over-hype of “3D Printing”. Yes it’s neat that they collected some local dirt, mixed it with some non-locally sourced water and binder, and poured it into an extruder run on some kind of non locally sourced energy, then sprayed it with some protective coating - it baffles me that people see this as a possible mainstream building technique. Running electrical, plumbing, air conditioning etc through this structure is doable but much harder, as the expectations of these niceties have evolved with modern construction and need easy access and hiding with things like dry wall.This almost reads as an onion article with the headline “brilliant scientists figure out how to overcomplicate the construction of mud huts similar to our earliest human ancestors”.
