U radu je prikazan postupak matematičkog modeliranja giroidne strukture, priprema modela epruveta za savojna i rastezna ispitivanja na kidalici, te priprema modela za ispis na 3D pisačima. S obzirom da je giroidna struktura veoma komplicirana, samim time dolazilo je do problema kod ispisa istih gdje se pojavljuju greške mrljavosti, odljepljivanja i zamaknuća kod ispisa. Eksperimentalnim putem utvrdilo se da je ispis tako složene strukture na 3D pisačima djelomično izvediv iako su postojali problemi kod ispisa. Rezultati ispitivanja i analize ukazuju da kod modela epruveta giroidne strukture dolazi do velikih odstupanja kod rasteznih i savojnih svojstava unatoč tome što su epruvete ispisivane istim postupcima i na istom pisaču što utječe na izazov ponovljivosti kvalitete ispisa.

The paper presents the procedure of mathematical modeling of the gyroid structure, the preparation of bending test tube models and extended testing on wooden boards and the preparation of a model for printing on 3D printers. Since the gyroid structure is very complicated, there is a problem with the printing where blotch errors occurred and lift-off from the printing bed appeared. Experimentally, it was found that printing of such complex structures on 3D printers are possible, although printing problems exist. The results of the tests and the analysis shows that the pattern of the tubular structure results in large differences in stretch and bending properties, although the tubes are printed same way on the same printer, which shows that there are problems with reproducibility of the print quality.
