    摘要： A method for processing an optically reactive material, particularly for manufacturing or structuring of an object. The method can include optically processing a starting material in a working volume by irradiating light of a first wavelength and light of a second wavelength different from the first wavelength, wherein at least one material property of the starting material is changed by the optical processing. The optical processing can include irradiating a first partial volume of the working volume at least partially filled with the starting material using the light of the first wavelength; irradiating the first partial volume of the working volume using the light of the second wavelength, wherein the light of the second wavelength is projected into the working volume; and irradiating a second partial volume of the working volume at least partially filled with the starting material, which is different from the first partial volume.

    摘要： The invention relates to a method for producing a three-dimensional object in an optically reactive starting material, comprising: providing an optically reactive starting material (4) in a working volume (5), wherein the optically reactive starting material (4) contains active molecules of a dual-color photoinitiator; and optically processing the starting material (4) to produce a three-dimensional object by radiating with light of a first wavelength and light of a second wavelength that is different from the first wavelength. The optical processing comprises the following: a) radiating the light of the first wavelength through an opening (20) of an entrance pupil (11) located upstream of an objective (12) and through the objective (12), wherein the objective (12) focuses the light of the first wavelength in the starting material into a focus volume in a focus of the objective (12) such that active molecules that absorb the light of the first wavelength transition into an intermediate state; b) radiating the light of the second wavelength via the entrance pupil (11) and the objective (12), wherein the objective (12) focuses the light of the second wavelength in the starting material (4) into the focus volume such that active molecules within the focus volume that are in the intermediate state and absorb the light of the second wavelength transition into a reactive state and a chemical reaction is thereby triggered in the focus volume, by means of which a material property of the starting material (4) is locally changed; and c) producing the three-dimensional object by repeating steps a) and b) for further focus volumes; wherein, during radiation, the light of the first wavelength and the light of the second wavelength are radiated, on the path to the focus volume, in a spatially non-overlapping manner at least when passing through the entrance pupil (11) and when passing through the objective (12) and in a spatially overlapping manner in the focus volume. Furthermore, a device for producing a three-dimensional object in an optically reactive starting material is provided.
