I'm a conservative believer in the printing tech. I'm an outright hater on the 'concrete ink' being used. Rael has the right idea with 3d printed adobe/cob/earth. The Cobbauge project is another interesting approach. There are questions of scale, (can a city be built within the footprint of the amount of sub-soil it would need to take), and questions of durability and pests. It also takes you into bizzare economic circumstances, with material that is nearly free, machinery that is very expensive up front, and labour costs that are still uncertain. BUT it looks to be more flexible and wet weather tolerant than rammed earth approaches.
