Abstract: The invention relates to a method for outputting a manufacturing file for producing an optical element (100) from a curable material (50) by using an additive manufacturing technology, comprising the steps of:—acquiring the desired geometry of the optical element,—obtaining a discretization of the desired geometry in volume units described by data relative to position parameters of the volume units and to the dimension of the volume units,—associating at least a volume unit with a kinetic parameter that relates to the curing pace imposed to the curable material of the volume unit,—producing, using at least one processor, a manufacturing file comprising said data and said kinetic parameter for manufacturing at least the optical element, and—outputting said manufacturing file.

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.
