Abstract

La présente invention concerne un dispositif d'impression pour la fabrication additive d'objet en trois dimensions par polymérisation successive de couches de résine comportant une structure de support permettant la réception d'une plateforme de fabrication de l'objet en trois dimensions et la réception d'une source optique, ladite plateforme, permettant le support de l'objet dans un bac de résine, étant mobile en translation verticale à chaque ajout de couche selon une hauteur fixe et tel que, selon l'invention le dispositif comprend en outre : - des moyens de mesure de la distance entre la source optique et la surface de la résine dans le bac, - des moyens d'ajustement verticaux et horizontaux de la position de la source optique, disposés sur la structure de support, en fonction des valeurs mesurées par lesdits moyens de mesure permettant d'obtenir une distance constante entre la source optique et la surface de la résine, - des moyens de commande du déplacement des moyens d'ajustement verticaux et horizontaux pour délivrer une commande de déplacement des moyens d'ajustement verticaux et horizontauxThe present invention relates to a printing device for the additive manufacturing of a three-dimensional object by successive polymerization of resin layers comprising a support structure allowing the reception of a platform for manufacturing the three-dimensional object and the reception. an optical source, said platform, allowing the object to be supported in a resin tank, being mobile in vertical translation with each addition of layer at a fixed height and such that, according to the invention, the device further comprises: - means for measuring the distance between the optical source and the surface of the resin in the tank, - means for vertical and horizontal adjustment of the position of the optical source, arranged on the support structure, according to the values measured by said measuring means making it possible to obtain a constant distance between the optical source and the surface of the resin, - means for controlling the displacement of the means vertical and horizontal adjustment for providing a command to move the vertical and horizontal adjustment means
