Abstract

The invention discloses a method and a device for preparing a complex structural piece from superior planet resources in situ, and relates to the technical field of aerospace. According to the scheme,the device is applied and used in the environments including microgravity and the like of a superior planet, superior planet soil is utilized in situ and is screened by the aid of a gas flow device,then soil powder is mixed with light-cured resin, evenly-mixed superior planet soil slurry is combined with a stereo lithography 3D printing technology, a structural piece is printed and formed and issintered in a sintering device, and the structural piece is prepared. The complex structural piece is prepared from the superior planet resources in situ, the device has very high environmental adaptability, the obtained structural piece can have the complex geometrical shape and is high in forming precision and good in surface quality, and then the progress of building a superior planet base tocarry out relevant scientific research can be accelerated; and meanwhile, the part has the relatively high density and the relatively high mechanical property after being sintered, so that the application range is broadened.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a method and a device for preparing complex structural parts by utilizing extraterrestrial planetary resources in situ. Background technique [0002] With the continuous development of science and technology, human beings' exploration of space is not limited to short-term stays, but is aimed at living and living for longer stays. The construction of extraterrestrial planetary bases such as moon bases and Mars bases has become a difficult problem for aerospace workers, and the construction of extraterrestrial planetary bases requires many structural parts, especially complex structural parts, such as: curved surface structural parts, Hollow structural parts, etc., its structure is complex. The manpower, financial and material resources consumed to realize this magnificent and huge aerospace project by transporting raw materials such as buildings up from the earth make it unrea...
