This paper presents the results of photopolymers used in rapid prototyping processes exploited in manufacturing of aircraft structural components on the basis of aircraft wheel hubs prototyping methods as Jetting Systems - JS and Stereolithography - SLA. Resins used in these techniques undergo polymerization process under specified conditions to form successive layers of RP model. Depending on the type of resin, the apparatus parameters, operating modes and model setting on the working platform various properties of prototypes are obtained. Knowledge of the actual physical, chemical (gel time, curing temperature, heat resistance) and mechanical parameters (of tensile strength, modulus, toughness, etc.) of the resin allows adequate definition of conditions and size of the load for RP model on the bench and introduce relevant characteristics of the resin in aim to determine the boundary conditions in numerical modeling including finite element method. The paper presents a comparative analysis of the parameters specified by the manufacturer differing from the actual tested strength parameters of RP resin. The standard test models were prepared under certain RP process parameters used to manufacture prototypes of aircraft wheel hubs. Desirability of special materials study for programming of SLA and JS prototyping processes was demonstrated by documented achievement of very good aircraft wheel hub prototype ensuring good prototyping effect for other elements of aircraft structures manufactured using different methods.
