Construction method of lunar base outer shell layer

Abstract

The invention discloses a construction method of a lunar base outer shell layer. The method comprises the following steps of designing and slicing a three-dimensional model diagram of the lunar base outer shell layer; spreading powder along the outer side of a lunar base inner shell layer by a powder sending cylinder and a pressing roller; selectively scanning a powder spreading layer by a laser so as to form a sintered layer; lifting the laser, the pressing roller, the powder sending cylinder and an auxiliary device at the same time by the thickness of one layer by utilizing a mechanical armevery time after one layer is sintered, then sending powder, spreading powder, slicing and scanning with a laser beam so as to form a new sintered layer again, and combining with the previous sinteredlayer; and repeating the process, and overlaying layer by layer until the whole lunar base outer shell layer is constructed. According to the construction method, lunar soil is used for directly printing the lunar base outer shell layer by utilizing a selective laser sintering process, so that the transportation cost of construction materials transported from the earth to the moon is reduced, a constructed lunar base has good compactibility and is easy to repair after being damaged, and the mode that a plurality of laser printers are operated at the same time can be adopted, so that the construction time is shortened.

Description

technical field [0001] The invention relates to the field of space base construction, in particular to a method for building the outer shell of a lunar base. Background technique [0002] The moon is the only natural satellite of the earth. The exploration and development of the moon is the first step for human beings to enter the vast universe. As early as the "Apollo" program in the 1960s and 1970s, humans began to conceive of building a lunar base. But so far there is no feasible method for building a lunar base. In response to this situation, the present invention proposes a method for building the outer shell of a lunar base; the moon is 384,400 kilometers away from the earth, and it takes 11 hours to transport 1kg of materials from the earth to the moon at present. ~$220,000, if transporting construction materials from the earth to the moon, it will cost a lot of money.

But so far there is no feasible method for building a lunar base. In response to this situation, the present invention proposes a method for building the outer shell of a lunar base; the moon is 384,400 kilometers away from the earth, and it takes 11 hours to transport 1kg of materials from the earth to the moon at present. ~$220,000, which would be prohibitively expensive to transport building materials from Earth to the Moon

[0003] Building a lunar base with traditional craftsmanship requires a lot of manpower and machinery, which is difficult to achieve on the moon
