A method cycle of a method for layerwise production of a tangible object (5) comprises the steps of: - solidifying a predetermined area of a layer (10) of a liquid (3) when said liquid layer (10) is adjoining a construction shape, so as to obtain a solid layer (14) of the tangible object (5); - separating said solid layer from said construction shape; and - moving, relative to one another, the separated solid layer and the construction shape to a predetermined position relative to one another for carrying out a successive such method cycle, so as to obtain a successive such solid layer adhered to the solid layer. For at least one of said method cycles, said solidifying and said separating are carried out such that solidifying of certain parts of the layer (14) takes place simultaneously with separating of other, already solidified parts of the layer.

Un procédé par cycles de fabrication par couches d'un objet tangible (5) consiste à solidifier une zone prédéterminée d'une couche (10) de liquide (3) lorsque ladite couche de liquide (10) est assemblée à une forme de construction, de manière à obtenir une couche solide (14) de l'objet tangible (5); à séparer ladite couche solide de ladite forme de construction; et à déplacer la couche solide séparée et la forme de construction dans une position prédéterminée l'une par rapport à l'autre, pour exécuter ledit cycle successivement, de manière que ladite couche solide adhère à la couche solide. Pour au moins un desdits cycles, le dit procédé de solidification et ledit procédé de séparation sont exécutés de sorte que la solidification de certaines parties de la couche (14) intervienne en même temps que la séparation d'autres parties déjà solidifiées de la couche.
