Tech experiment - 3D printing metal parts in conditions similar to Lunar surface

Technological experiment on the way to 3D printing metal parts on a lunar surface. Direct Metal Evaporation And Condensation method. - lunar regolith consists with some, non zero amount of metals; - extraction of different metals, can be done by applying different temperatures; - vacuum conditions allow to do this with precision; - Direct Metal Evaporation will be done inside evaporation chamber directly from a lunar regolith, or from already extracted metals; - Condensation of the evaporated metal can be done on even surface with temperature up to 200C; - Evaporation chamber can be positioned by applying the 3D printing technique; Other technique - condensation surface can be a cavity formed by applying parts to a surface, and evaporation chamber could be fixed till a moment when metal will fill up mold's cavity. Well, it is slow, but it can be precise, and in a case of remote controlled from the earth time is not critical. Promising part of the story - on the Earth and at zero-gravity the same technique allows to 3D print parts with better precision than existing technologies.
