The possibility of application of chosen Rapid Prototyping (RP) resins for photoelastic testing in this paper is presented. The aim of the work was to compare usefulness of available resin test models to be directly applied for photoelastic experiment. The RP resin test models were compared with vacuum casted resin model (as a reference model) commonly used for photo-elastic testing of machine parts. The models for tests were fabricated using chosen Rapid Prototyping (RP) techniques: Stereolitography (3D Systems Sl5170 epoxy resin), Polyjet (Objet Fullcure 720 epoxy resin) and vacuum casting method (Epidian 5 epoxy resin). In the paper the evaluation process of fabricated RP models was described. The experiment assumptions, the fields of possible application of chosen RP materials, technological consideration of complex models testing in this article were pointed.
