Sažetak

Intensive development of manufacturing technologies, in particular additive technologies, resulted in new possibilities of making cellular structure models. In this paper the cellular structure samples made of polymer resins in the PolyJet Matrix additive technology were investigated. Relaxation tests according to ISO 3384 were carried out. The influence of geometric structure shape on rheological properties was determined and the most favourable geometric variants of cellular structure models were determined. Using Mathematica and Origin software, a statistical analysis of test results was carried out, along with the determination of five-parameter functions approximating the relaxation curves. The rheological model was adopted and its parameters were determined.
