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 processing an optically reactive material, comprising: providing a starting material (3), which is optically reactive and fills a working volume (2); and optically processing the starting material (3) in the working volume (2) by means of irradiation of light of a first wavelength and of a second wavelength, wherein the light of the first wavelength and of the second wavelength is provided by a lighting device and at least one material property of the starting material is changed by means of the optical processing and the optical processing comprises the following: irradiating a first partial layer volume of the working volume (2) filled with the starting material (3) using the light of the first wavelength; irradiating the first partial layer volume of the working volume (2) using the light of the second wavelength, wherein the light of the second wavelength is projected into the working volume (2) by means of a projection device (7) capturing only the first partial layer volume wholly or partially; irradiating a second partial layer volume of the working volume (2) filled with the starting material (3), which is different from the first partial layer volume, using the light of the first wavelength; irradiating the second partial layer volume of the working volume (2) using the light of the second wavelength, wherein the light of the second wavelength is projected into the working volume (2) by means of the projection device (7) capturing only the second partial layer volume wholly or partially; and repeating the preceding steps for layer-by-layer optical processing of the starting material (3) in the working volume (2) until a volume of the starting material (3) to be processed, which captures the working volume (2) wholly or partially, is optically processed. Furthermore, a device for processing an optically reactive material is provided.

摘要： The present invention relates to a process, an apparatus and photoswitchable photoinitiators for locally polymerizing a starting material by dual color photopolymerization and a method for volumetric printing of a shaped body (xolography). In particular, photoinitiators are provided, which cause raring of photopolymerizable formulations upon irradiation with two different wavelengths and which maybe used for volumetric printing (xolocure initiators).
