Title
(EN) A SYSTEM AND METHOD FOR THREE-DIMENSIONAL (3D) PRINTING
(FR) SYSTÈME ET PROCÉDÉ D'IMPRESSION TRIDIMENSIONNELLE (3D)
Abstract
(EN) A method for a three-dimensional (3D) printing includes obtaining a 3D model for printing, the 3D model comprised of a plurality of horizontal layers each horizontal layer being comprised of pixels; analyzing, a given layer, to identify one or more reinforcement areas comprised of reinforcement pixels of the pixels, wherein each given reinforcement area of the reinforcement areas is: (a) associated with a full projection pattern so that the reinforcement pixels are projection pixels, (b) corresponds to an area, within a preceding layer preceding the given layer, that includes projection pixels only, and (c) located at a distance higher than a threshold from the no-projection pixels, within the layer and within the preceding layer; causing, a projector to project the projection pixels of the given layer; after completion of a given layer, moving a movable stage, to enable printing of a subsequent layer of the horizontal layers.
(FR) L'invention concerne un procédé d'impression tridimensionnelle (3D) consistant à obtenir un modèle 3D pour l'impression, le modèle 3D comprenant une pluralité de couches horizontales, chaque couche horizontale étant constituée de pixels ; à analyser une couche donnée pour identifier une ou plusieurs zones de renforcement constituées de pixels de renforcement des pixels, chaque zone de renforcement donnée des zones de renforcement : (a) étant associée à un motif de projection complet de telle sorte que les pixels de renforcement sont des pixels de projection, (b) correspondant à une zone, au sein d'une couche précédente précédant la couche donnée, qui comprend des pixels de projection uniquement, et (c) étant située à une distance supérieure à un seuil par rapport aux pixels non de projection, au sein de la couche et au sein de la couche précédente ; à amener un projecteur à projeter les pixels de projection de la couche donnée ; après l'achèvement d'une couche donnée, à déplacer un étage mobile, pour permettre l'impression d'une couche subséquente des couches horizontales.
