A method for producing a model of a human or animal organ or a part thereof or of some other segment of human or animal body, comprising the steps of: a) providing precaptured structural geometric data of the organ, organ part or segment to be replicated which data from a data set composed of information relating to a material type or material class assigned to a three-dimensional positioning in space and, as a result, provide spatial coordinates for materials such as connective tissue, cells (1, 2), fluid regions, empty space, wherein the structural geometric data are obtained from stained section images, preferably immunohistologically stained section images or in that the structural geometric data have been determined non-invasively on a living body, b) selecting reconstitution materials for the organ, organ part or segment to be replicated comprising at least the following groups: at least one material for the reconstruction of an extracellular matrix and at least one type of organ specific cells (1, 2); c) assigning the structural geometric data to the individual selected reconstitution materials on the basis of measured values from section images, particularly, from colour values, degrees of darkness, measured intensities or contrast values; d) assembling the 3D model layer by layer through successive application of side selective assembly methods for each single layer for at least some of the reconstruction materials, which comprises at least one matrix material and at least one type of organ specific cells, on the basis of an associated data set, wherein only side selective assembly methods are applied or they are combined with further methods such as coating methods or filling methods and wherein the side selective assembly method used for the layer by layer replication of the cellular layers and regions is a laser induced forward transfer (LIFT) of the cells. a) providing precaptured structural geometric data of the organ, organ part or segment to be replicated which data from a data set composed of information relating to a material type or material class assigned to a three-dimensional positioning in space and, as a result, provide spatial coordinates for materials such as connective tissue, cells (1, 2), fluid regions, empty space, wherein the structural geometric data are obtained from stained section images, preferably immunohistologically stained section images or in that the structural geometric data have been determined non-invasively on a living body, b) selecting reconstitution materials for the organ, organ part or segment to be replicated comprising at least the following groups: at least one material for the reconstruction of an extracellular matrix and at least one type of organ specific cells (1, 2); c) assigning the structural geometric data to the individual selected reconstitution materials on the basis of measured values from section images, particularly, from colour values, degrees of darkness, measured intensities or contrast values; d) assembling the 3D model layer by layer through successive application of side selective assembly methods for each single layer for at least some of the reconstruction materials, which comprises at least one matrix material and at least one type of organ specific cells, on the basis of an associated data set, wherein only side selective assembly methods are applied or they are combined with further methods such as coating methods or filling methods and wherein the side selective assembly method used for the layer by layer replication of the cellular layers and regions is a laser induced forward transfer (LIFT) of the cells.
