Method for manufacturing an optical element from a curable material using an additive manufacturing technology comprising steps of: - providing a first portion of uncured curable material, - forming a first part of the optical element by irradiating the surface of the curable material of said first portion with a first curing surface energy (E 1), the first curing surface energy (E 1) being strictly lower than a first predetermined energy threshold (T 1) and higher than a second predetermined threshold (T 2), the first predetermined energy threshold (T 1) being lower than or equal to a solid predetermined energy threshold (T S) corresponding to an energy sufficient to make the first part of the optical element solid on the whole thickness of said first part of the optical element, the second predetermined energy threshold (T 2) being equal to an induction surface energy (E I), and - forming, after the irradiation of the first part with the first curing surface energy (E 1), 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, said second curing surface energy being higher than the second predetermined energy threshold (T 2) the surface of the curable material, the second curing surface energy irradiating both the second part of the optical element and at least a portion of the first part of the optical element, the sum of the first curing surface energy (E 1) and the portions of the at least second curing surface energy received by said first part of the optical element being sufficient to make the first part of the optical element solid, the sum of the first curing surface energy (E 1) and the portions of the at least second curing surface energy received by said first part of the optical element being preferably higher than or equal to the solid predetermined energy threshold (T S). - providing a first portion of uncured curable material, - forming a first part of the optical element by irradiating the surface of the curable material of said first portion with a first curing surface energy (E 1), the first curing surface energy (E 1) being strictly lower than a first predetermined energy threshold (T 1) and higher than a second predetermined threshold (T 2), the first predetermined energy threshold (T 1) being lower than or equal to a solid predetermined energy threshold (T S) corresponding to an energy sufficient to make the first part of the optical element solid on the whole thickness of said first part of the optical element, the second predetermined energy threshold (T 2) being equal to an induction surface energy (E I), and - forming, after the irradiation of the first part with the first curing surface energy (E 1), 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, said second curing surface energy being higher than the second predetermined energy threshold (T 2) the surface of the curable material, the second curing surface energy irradiating both the second part of the optical element and at least a portion of the first part of the optical element, the sum of the first curing surface energy (E 1) and the portions of the at least second curing surface energy received by said first part of the optical element being sufficient to make the first part of the optical element solid, the sum of the first curing surface energy (E 1) and the portions of the at least second curing surface energy received by said first part of the optical element being preferably higher than or equal to the solid predetermined energy threshold (T S).
