Manufacturing system configured to carry out a method for additively manufacturing an ophthalmic device and such a method

A method for additively manufacturing an ophthalmic device layer by layer, the manufacturing method comprising the steps of:

• providing a manufacturing system (1) having a tank (10) filled with a volume of a predetermined material (11), a building platform (20) on which layers (3) made from the predetermined material are formed, a curing device (12) configured for at least partially hardening the layers of the ophthalmic device to be manufactured, a transparent plate (21) located between the building platform (20) and the curing device (13), and a flexible separation film (22) mechanically connected by ends (31) to a frame (30) and at least partially located between the transparent plate (21) and the building platform (20);
• controlling the additive manufacturing system (1) so that the transparent plate, the flexible separation film and the building platform are moved one relative to the other and admit first relative positions corresponding to building positions of a layer, in which the transparent plate is applied against the flexible separation film which is in a tense state;
• and
• controlling the additive manufacturing system (1) so that transparent plate, the flexible separation film and the building platform are moved one relative to the other and admit second relative positions corresponding to layering positions of a layer, in which the transparent plate is moved relative to the frame and is remote to the flexible separation film which is at least partially in a loose state,
• wherein the transparent plate, the frame, and the building platform are movable relative to one another and to the tank between the respective first relative position and the respective second relative position.
