Abstract
We proposed extremely simple and low-cost conception of slow lunar apartment building using solar energy and lunar material - regolith and basalts. When solar radiation is focused into small patch, temperature inside the patch will be more than 3000K that is enough to melt any lunar material. Having concave film mirror 4-meters in diameter, we can melt about 10 g of stony material every second. If this material is in sands form, it may be poured into light patch to produce monolith construction. Such 3-D printer may be programmed for building any complex construction of walls, floors, studs, stairs, hatches and so on. One 3-D printer with 4-meter mirror can produce about 3,4... 4,0 m3 of monolith construction during one lunar day and 120-tonn building after 1 year work. During lunar night the printer will be at inoperative mode, but it will not be broken. After sunrise it will continue its work. Assuming that thickness of walls and studs would be 50-cm (to protect rooms from space radiation and micrometeorites), the 120-tonn building will have at least 21 m2 of gas proof room. Such light 3-D printer may be delivered to the landing point several years before manned mission, so when astronauts will install proper lids and life support system, they will have enough habitable room for long work.
