1. A method for outputting a manufacturing file for producing an optical element from a curable material by using an additive manufacturing technology, comprising:
acquiring a 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;
and further comprising:
associating at least a volume unit with a kinetic parameter that enables control of a curing pace imposed to the curable material of said at least a volume unit;
producing, using at least one processor, a manufacturing file comprising said data and said kinetic parameter associated to said at least a volume unit for manufacturing at least the optical element; and
outputting said manufacturing file;
wherein control of the curing pace controls optical homogeneity between the cured volume units.
