If humans move to Mars, what new requirements do people have for building decoration materials?

"Within 10 years, human footprints will be printed on Mars" is the goal announced by NASA, and it is still unknown whether this grand plan can be completed.

However, scientists have begun to design and develop the residences of Martian immigrants. The harsh living environment of Mars made the first group of Martian colonists have to face the problem first, because you didn't go to Mars to die, "survival" came first!

Mars Palace must be protected from radiation and cold. This goal seems to be well achieved, and scientists can design and produce this building material on earth. But how to send it to Mars? The carrying capacity of the rocket denies the possibility that "building materials come entirely from the earth"!

The building materials of Mars House can only come from Mars! Martian soil is rich in iron oxide. It is the only feasible way to use the increasingly mature 3D printing technology, make rational use of Martian soil and build a Mars house!
