Get ready for buildings a whole lot more complex and cheaper and creative.
My first thought is that the time, trouble and logistics to transport the 3D builder to the site coupled with the site preparation, dealing with weather, excess room required for the builder would limit the type and frequency of structures that could be built.
In the end, I think that premanufactured panels, modules and components of a structure in a controlled environment would be quicker, more efficient and cheaper.
Maybe for building a base on the moon out of local media or something like that would be the best use....
just a few thoughts.
Didn’t read the article so bear with me
Saw a great show on 3D printing pressurizable lunar habitats for moon exploration. I believe they heated to the melting point the lunar regolith that they used as a building material. They practiced on earth with a similar material. We live in amazing times......if we don’t blow ourselves off the face of the earth.
Whole lot of guys are going to be out of work. Probably kitchens and bathrooms offer some opportunity later to get in on the closest thing to a ground floor. At some point printers capable of printing countertops will be available, meanwhile if you save on the building itself you might be more apt to spend a fortune on pretty kitchens and bathrooms.
3D print a Mohammed, and drop it in the middle of Mecca, with a sign that says, “I’m back”. sit back and watch what happens. Endless hours of entertainment.
