(54) Title (FR): PROCÉDÉ ET SYSTÈME DE MISE À NIVEAU D'UNE COUCHE DANS UNE FABRICATION DE FORME LIBRE

(57) Abstract:
(EN): A method of fabricating an object in layers, comprises, for at least one layer: dispensing a building material formulation to form a first portion of the layer, and leveling the first portion by a leveling device; increasing a vertical distance between the first portion and the leveling device; and while a topmost surface of the first portion is exposed and beneath a segment of the leveling device: dispensing a building material formulation to form a second portion of the layer, laterally displaced from the first portion along an indexing direction, and leveling the second portion by the leveling device.
(FR): L'invention concerne un procédé de fabrication d'un objet en couches comprenant, pour au moins une couche : la distribution d'une formulation de matériau de construction pour former une première partie de la couche et la mise à niveau de la première partie par un dispositif de mise à niveau ; l'augmentation d'une distance verticale entre la première partie et le dispositif de mise à niveau ; et tandis qu'une surface la plus au-dessus de la première partie est exposée et en dessous d'un segment du dispositif de nivellement : la distribution d'une formulation de matériau de construction pour former une seconde partie de la couche, déplacée latéralement par rapport à la première partie le long d'une direction d'indexation, et la mise à niveau de la seconde partie par le dispositif de mise à niveau.
