Abstract: A manufacturing system carries out a method for additively manufacturing ophthalmic devices, and includes a tank filled with a predetermined material, a single curing device for curing volumes of the predetermined material to harden layers of the ophthalmic devices, a layering device for layering volumes of the predetermined material onto harden layers of the ophthalmic devices. The manufacturing system includes building platforms movable relative to the tank and on which are supported the ophthalmic devices.
