Efficient 3D printing device and method for preparing high-strength complex component through extraterrestrial planet in-situ resources

Abstract

The invention discloses a high-efficiency 3D printing device and method for preparing a complex component through extraterrestrial planet in-situ resources, and belongs to the field of space additive manufacturing. The method comprises the following steps of: firstly, providing a mixture raw material consisting of extraterrestrial planet soil particles and a resin binder, then providing a first laser beam and a second laser beam, forming a large-range irradiation area by using the first laser beam and preheating, irradiating a part of the area in the irradiation range of the first laser beam by using the second laser beam, and irradiating the part of the area in the irradiation range of the second laser beam by using the resin binder. Melting and bonding to form a structure; in the whole process, continuous feeding of the mixture raw materials, irradiation of the first laser beam and irradiation of the second laser beam are kept to be controlled by a master controller, all links are precisely connected, and a high-strength complex component is printed in a 3D mode through the modes of large-range preheating, heating melting, cooling solidification and layer-by-layer stacking of each layer. Due to the fact that the first laser beam preheats the mixed material in a large range, the second laser beam can melt and bond the material more quickly, and the 3D printing efficiency is greatly improved. In-situ resources of an extraterrestrial planet environment are utilized as printing raw materials, and the 3D printing method is suitable for manufacturing of extraterrestrial planets in shortage of resources and 3D printing manufacturing of large components or bearing structures of future extraterrestrial planet bases.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a method and device for laser 3D printing using in-situ resources of extraterrestrial planets. Background technique [0002] Deep space exploration is an important development direction of scientific and technological development. With the improvement of our country's scientific and technological strength, significant improvements have been made in deep space detection capabilities. With the continuous development of the lunar exploration project and the Saturn exploration project, the construction of outer space bases and infrastructure has been put on the agenda. However, if the construction materials are all made of resources on the earth, the construction cost will be greatly increased, and it is a very economical way to use in-situ resources in outer space as much as possible. In particular, there are abundant lunar soil resources available on the moon. The lunar soil components m...
