GENIAL : Habitat gonflable sur Mars et la Lune : Pneumo Planet
Un nouveau concept d'habitat for pour Mars ou la Lune
It is based on an inflatable structure shielded by a deposit of regolith. It also reflects natural sunlight into the habitat. So there is plenty of sunlight to grow plants for self sufficient production of food and oxygen, and to heat the habitat.
High energy consuming 3D print technology is not needed for that structure.
