C\u2019est une possibilit\u00e9 que l\u2019ESA et ses partenaires industriels \u00e9tudient actuellement afin d\u2019utiliser la technique r\u00e9volutionnaire de l\u2019impression 3D pour cr\u00e9er une base directement sur le sol lunaire.<\/p>\n<\/div>\n<p>L\u2019impression 3D n\u00e9cessite une machine sp\u00e9ciale, fournie par l\u2019entreprise britannique Monolite. Cette technique permet d\u2019assembler un objet solide couche par couche. Le projet de base lunaire de l\u2019ESA utilise une imprimante sp\u00e9ciale qui comporte une rang\u00e9e de buses d'impression permettant de consolider, par pulv\u00e9risation d\u2019une solution adh\u00e9sive, un mat\u00e9riau ressemblant \u00e0 du sable et similaire au sol lunaire.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"945\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2013\/02\/1.5_tonne_building_block_produced_as_a_demonstration\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2013\/02\/1.5_tonne_building_block_produced_as_a_demonstration\/18245255-2-eng-GB\/1.5_tonne_building_block_produced_as_a_demonstration.jpg\" alt=\"1.5 tonne building block produced as a demonstration\"><figcaption>1.5 tonne building block produced as a demonstration<\/figcaption><\/figure>\n<p>\u00ab Tout d\u2019abord, nous devons m\u00e9langer le mat\u00e9riau lunaire artificiel avec de l'oxyde de magn\u00e9sium.

Des facteurs thermiques tels que les temp\u00e9ratures lunaires extr\u00eames devront \u00e9galement faire l\u2019objet d\u2019une \u00e9tude, car l\u2019impression 3D est faite pour fonctionner \u00e0 temp\u00e9rature ambiante.
