Methods and systems for manufacturing optical volume elements from curable materials using additive manufacturing techniques

摘要

A method for manufacturing an optical element (100) from a curable material (50) using additive manufacturing techniques, the method comprising: - providing a first portion of the curable material (50); - a surface of the curable material with a first cured surface energy; forming a first part of the optical element by irradiating (55), wherein a first hardened surface energy is strictly lower than a first predetermined energy threshold and higher than a second predetermined threshold; and - at least a second part of the optical element separated from the first part of the optical element by irradiating the surface of the curable material with at least a second hardened surface energy after irradiating the first part with the first hardened surface energy. forming, wherein the second hardened surface energy illuminates both the second part of the optical element 100 and at least a portion of the first part of the optical element, wherein the sum of the first hardened surface energy and the at least second hardened surface energy is greater than or equal to a first predetermined energy threshold. A manufacturing system (1) for manufacturing an optical element.
