Abstract
The disclosure provides an additive manufacturing system comprising 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, 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), the additive manufacturing system (1) being configured so that the transparent plate, the flexible separation film and the building platform are movable 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 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.
