Abstract

The article provides an analysis and comparison of 3D printing options for lunar regolith using solar and laser radiation. This technology may be in demand during the construction of lunar base facilities. An urgent task is to analyze possible methods of constructing structures of various structures on the Moon and, first of all, to solve the issue of obtaining building materials from the lunar soil. The most optimal construction technology from local materials is considered to be the 3D sintering method. 
An analysis of the options for constructing regolith fusion systems shows that the combined method with indirect solar sintering retains the advantages of both the method of direct use of solar energy (high efficiency) and the advantages of using a laser source (mobility of the complex). At the same time, it reduces the disadvantages of these basic methods: the size of the main concentrator and the low maneuverability of the direct sintering system, and as a result, the limitation on construction tasks, as well as serious losses in the efficiency of laser sintering.The use of a number of modifications, such as «Sun Simba» concentrators, hollow light guides for delivering energy to the output and rod, and the sapphire glass output rod design will further increase the efficiency of the indirect solar sintering method.
