Spiral City

When I read that it was possible to create marble-like structures with 3D printers (e.g. D-Shape) by binding sand or gravel together, it got me thinking about how the technology might evolve in the future.

This is what I have come up with.

Standard 3D sandstone printers (wouldn't it be cool if they were common enough for there to be a standard) work by putting down layers of material one on top of the next to build a structure from the ground up. These sort of printers will be capable of building awesome monuments & designer buildings, but what could be even more useful is a 3D printer mounted on wheels or tracks. It could be used to build roads or walls in sandy areas. After depositing a layer of rock the printer could move forward slightly before moving on to the next layer. Looking inside the printer from the side you would see a series of steps, but it would appear like the road or wall or what ever you were building was being extruded from the back of the printer.

Thinking even bigger, gigantic 3D printers could build whole cities, by spiraling ever outwards from a starting point. Apartments, offices, shops, pathways, roads, conduits etc., could be built simultaneously, and a green space could be left between the spirals for the growing of food, and outdoor recreation.

The design of the city could be planned out years in advance, or be semi-random so that the latest section would always be a surprise.

What do you all think? Could this work?
