Abstract

L'invention concerne un procédé de production d'un objet moulé en céramique, qui produit un objet moulé en céramique par (i) une étape consistant à lisser une poudre de céramique pour former une couche de poudre, (ii) une étape consistant à envoyer un faisceau laser sur la couche de poudre sur la base de données tridimensionnelles pour cristalliser les sites exposés au faisceau laser, et (iii) la répétition des étapes (i) et (ii), caractérisé en ce que, à l'étape (ii), le faisceau laser envoyé sur la surface de la couche de poudre n'est pas focalisé.
