Abstract
(EN)
A three-dimensional printing system (2) includes a support plate (6) and a resin vessel (16). The support plate (6) defines a central opening (8) and an upper surface (14). The resin vessel (16) is disposed upon the upper surface (14) of the support plate (6) and includes a substructure (18) and a transparent sheet (20). The substructure (18) includes a vertical wall (46) and a tension ring (48) that extends inwardly and downwardly from the vertical wall (46). The tension ring (48) impinges downwardly upon an upper surface of the transparent sheet (20) and tensions the transparent sheet (20).

La présente invention concerne un système d’impression tridimensionnelle (2) qui comprend une plaque de support (6) et un récipient de résine (16). La plaque de support (6) délimite une ouverture centrale (8) et une surface supérieure (14). Le récipient de résine (16) est disposé sur la surface supérieure (14) de la plaque de support (6) et comprend une sous-structure (18) et une feuille transparente (20). La sous-structure (18) comprend une paroi verticale (46) et une bague de tension (48) qui s’étend vers l’intérieur et vers le bas depuis la paroi verticale (46). La bague de tension (48) frappe vers le bas sur une surface supérieure de la feuille transparente (20) et tend cette dernière (20).
