Hello. My name is Georgiy and I am from Ukraine. I would like to offer you a project of a building for the first Martian colonists which is done using the technology of 3d-printing. The main idea of the project is the minimal usage of subsidiary building materials such as cranes, check rales, hawsers for loads suspension, etc. The reason is that after finishing the building all these materials become useless and their delivery on such distances is quite expensive and will entail significant difficulties. Taking into account all these facts, the most convenient solution is to use the printing robot for such building. When choosing the building sight the printing robot creates himself the constructions necessary for manufacturing works, and these constructions later become the walls of the buildings. This approach allows economizing on the delivered materials and decreases the influence of the external factors. Modularity of the building provides a possibility of the next completion of new sections, and this also allows economizing on materials, continuing building while having some blocks partially inhabited, and reducing overall expenses on energy and resources. Modules do for both living and growing up the food. Equipment that is not susceptible to the influence of external factors is placed on the outside of the modules in order to save the internal space of the buildings and is covered with a light rounded roof in so that to save it from the dust. Power supply is put into effect using solar panels near the buildings.
