Suivez @numerama pour anticiper l'avenir ! Des physiciens de l'université d'Amsterdam ont réussi à imprimer une structure de glace en 3D, en l'occurence un sapin de 8 centimètres ! La technique utilisée par les chercheurs s'appelle le refroidissement par évaporation, un principe physique qui fait qu'un objet se refroidit quand de la vapeur s'en dégage. La technologie pourrait servir à construire des structure 3D à moindre coût et impact écologique car il n'y a pas de résidu si ce n'est une flaque d'eau (à condition qu'il fasse froid). ️ Dans leur prépublication, les chercheurs évoquent par exemple une potentielle utilisation sur d'autres planète (comme Mars), où la température le permettrait pour construire toutes sortes de structures. __ #numerama #impression3d #tech #sciences #recherche #innovation
