Method for volumetric printing a three-dimensional object by multi-color photopolymerization of a photocurable resin

An apparatus for volumetric printing a three-dimensional object by multi-color photopolymerization of a photocurable resin, which comprises an irradiation device for performing an irradiation process of irradiating, on basis of a plurality of printing parameters, a photocurable resin with light of a first wavelength and light of a second wavelength, different from the first wavelength to form, by multi-color photopolymerization, a three-dimensional object in at least one direction, wherein the light of the first wavelength and the light of the second wavelength intersect in a formation zone, wherein the apparatus comprises a controller configured to spatially and/or temporally vary at least one printing parameter, particularly a printing parameter influencing the curing behavior of the photocurable resin, during the irradiation process.
