It is known that the delivery of each kilogram of payload to Mars costs a lot of money - more than $ 100, 000, while the transport capabilities of the spacecraft will be very limited. It is not surprising that even now, many years before the planned start of the first Martian mission, scientists are racking their brains about how to save money.
Researchers from NASA and the University of Central Florida have proposed a solution to the "housing problem" of the first Martian colonists by building houses from "local" materials - Martian soil, from which "ink" will be made for a construction 3D printer.
The dwellings are supposed to be built from regolith, which will be melted in a special chamber at a temperature of 1650 ° C, after which it will be subjected to electrolysis. This will allow you to extract the necessary metals and vital oxygen from it.
The molten metal can then be used as a component of the "ink" for a 3D printer to print parts of the Martian houses, much like an igloo concept.
It should be noted that the use of 3D printing technologies in construction is no longer news. So in Dubai (UAE), several office buildings have been built, and Chinese companies offer the construction of up to 10 printed houses per day.
