Embodiment 1
[0031] Such as figure 1 As shown, the embodiment of the present invention provides a method for preparing complex structural parts in situ using extraterrestrial planetary resources. The method is implemented in the microgravity environment of the extraterrestrial planet, including the following steps:
[0032] S1, collecting extraterrestrial planet soil and sieving it to obtain soil powder with a particle size ranging from 0.01 μm to 20 mm;
[0033] S2, mixing the soil powder with the photocurable resin to obtain an exoplanet soil slurry with a viscosity in the range of 2 to 100 Pa·s;
[0034] S3, use the extraterrestrial planetary soil slurry, adopt stereolithography 3D printing to form, and obtain a stereolithography 3D print, the minimum pixel size of the light source of the print is 50 μm, the dimensional accuracy error is within 0.5%, and the surface roughness is in Below 5μm;
[0035] S4, sintering the stereolithographic 3D printed parts to complete the preparation of...
Embodiment 2
[0055] Such as figure 2 As shown, the embodiment of the present invention provides a device for preparing complex structural parts in situ using extraterrestrial planetary resources, including: a slurry mixing device 9, the inlet of the slurry mixing device 9 is screened with the soil of the extraterrestrial planet respectively The device 4 is connected to the photocurable resin magazine 1, the outlet of the slurry mixing device 9 is connected to the slurry collection and storage device 14, and a stereolithography 3D printing device 17 is arranged above the slurry collection and storage device 14, and the slurry A sintering device 15 is arranged behind the material collection and storage device 14 , wherein the inlet of the exoplanet soil screening device 4 is connected to the air flow device 3 .
[0056] The process of using the above-mentioned device is as follows:
[0057] Such as figure 2 As shown, by connecting the inlet of the slurry mixing device 9 with the exoplane...
