Abstract
This paper presents the results of laboratory studies on the use of a new technology of selective laser melting to obtain experimental products from the lunar regolith without special additives. The main properties of the natural regolith, which significantly affect the fusion process, are determined. The first samples of a given geometry were obtained from labradorite and gabbro-diabase powders, which are natural analogues of lunar regolith, using this technology. The research results are planned to be used in the preparation of initial data for the development of the Lunar Printer space device as part of the complex of scientific equipment of the promising lunar project Luna-Grunt.
