Abstract: The invention relates to a method (100) for manufacturing anatomical models (1) adapted to simulate organs or parts of organs (2) of a patient. The method comprises the steps of: - obtaining (101) information on the anatomical structure of an organ or part of an organ by processing digital images of said organ; - selecting (102), by means of digital image processing software, elements of the anatomical structure of the organ or part of the organ from the processed images to obtain (103) a three-dimensional computerized model of the anatomical structure of said organ; - representing (104) the three-dimensional computerized model by means of a file (STL) having a valid format usable in a three-dimensional printing process; - manufacturing (105) the representative anatomical model of the organ to be simulated by means of the three-dimensional printing process. Said step of manufacturing comprises the further steps of: - providing (106') a first software library including digital data representative of a plurality of materials usable for manufacturing the anatomical model of the organ to be simulated; - providing (106'') a second software library including digital data representative of a plurality of methods for manufacturing the anatomical model of the organ to be simulated; said manufacturing methods are usable either alternatively or mutually in combination in the three-dimensional printing process; - selecting (107) at least one material from the first software library and at least one manufacturing method from the second software library based on a parameter representative of a hardness measurement of said organ to be simulated; - modifying (108) the file representative of the three-dimensional computerized model based on the at least one material and the at least one manufacturing method selected to generate a further file (STL1) representative of the modified three-dimensional computerized model; - using (109) the further modified file (STL1) to perform the process for manufacturing the anatomical model by means of a three-dimensional printing unit (204).
