A method for designing or replicating a human or animal organ in the form of a functional model includes providing previously recorded structural-geometric data of the organ or organ part to be replicated, selecting reconstruction materials for the organ or organ part, allocating the structural-geometric data to the individually selected reconstruction materials, and carrying out a layered assembly by the model by successively applying site-selective assembly methods for at least one part of the reconstruction materials on the basis of an associated data set.
