Abstract

Ce procédé comporte : la fourniture (212) du matériau dans un état de poudre en plusieurs points de l'espace ; et, en fonction du point de l'espace, soit l'agrégation (214) du matériau pour le faire passer à l'état solide, soit le maintien du matériau à l'état de poudre. Le matéri au à l'état solide formant la pièce (104) délimite au moins une cavité fermée (402) remplie du matériau laissé à l'état de poudre.
