From Andrey:

It has been two years since I first began toying with the idea of a 3D printer that was capable of constructing homes. In my vision of using 3D printers as new technology, I wanted a light, portable, and stable machine. First, I built a small 3D printer that used plastic for its main material, and from that, I started experimenting on enlarging the printer and using variations of cement mixes. Layering cement was an extremely difficult task- it required extensive tuning of the printer on a programming level, as well as using exact quantities for the cement mix. While testing the printer, I ran into obstacles (such as the nightmare of the extruder clogging) and discovered even further abilities of the printer, like that it can print much more than 50cm a day as I originally thought.
