For the analysis of complex medical issues, besides numerical methods, one can simultaneously make use of experimental tests to verify the obtained results. In the case of an experimental test it is necessary to make physical models and to carry out verifying tests on them. The physical model of the examined object can be fabricated with Rapid Prototyping technology from 3D-CAD virtual model. The Physical Rapid Prototyping model enables identifying the medical problem more efficiently and reconstructing the pathological changes clearly for experimental tests. Based on the medical model of real anatomical structures it is possible to manufacture experimental models that reconstruct complex inner structures very precisely. It allows avoiding simplified assumptions to experimental analysis. The photoelastic method can be used to verify the numerical analysis of the stress distribution in spatial models. The experimental research can be performed on real objects or their models. The photoelastic method is mainly used in cases where the stress distribution needs to be tested in those object areas that are difficult to access or the inner areas of structures. Some aspects of application of Rapid Prototyping (RP) methods to photoelastic tests are presented in this paper. The comparative analysis of the usefulness of available RP resin models applied to photoelastic experiment is performed. The process of preparation of an experimental model for the photoelastic method is described. The usefulness of the chosen RP resins for experimental tests is confirmed.
