    Abstract: A method for manufacturing an optical element (100) from a curable material (50) using an additive manufacturing technology comprising steps of: - providing a first portion of curable material (50), - forming a first part of the optical element by irradiating the surface (55) of the curable material with a first curing surface energy, the first curing surface energy being strictly lower than a first predetermined energy threshold and higher than a second predetermined threshold, and - forming, after the irradiation of the first part with the first curing surface energy, at least a second part of the optical element, distinct from the first part of the optical element, by irradiating, with at least a second curing surface energy, the surface of the curable material, the second curing surface energy irradiating both the second part of the optical element (100) and at least a portion of the first part of the optical element, the sum of the first curing surface energy and the at least second curing surface energy being higher than or equal to the first predetermined energy threshold. A manufacturing system (1) for manufacturing an optical element.
