ANALIZA UTJECAJA RADNE TEMPERATURE NA MEHANIČKA SVOJSTVA MODELA IZRAĐENIH POSTUPKOM 3D ISPISA

U radu je analiziran utjecaj temperature ispisa i temperature podloge na mehanička svojstva ispitivanih uzoraka. Utjecaj temperature najvažniji je čimbenik pri trodimenzionalnoj izradi modela. Upravo iz tog razloga, prikazana je izrada savojnih i rasteznih ispitnih uzoraka uz promjenu temperature ispisa i temperature podloge. Eksperimentalnim putem utvrđeno je dimenzijsko odstupanje uzoraka od zadanih parametara tijekom 3D ispisa, što je i glavni nedostatak ovakve vrste pisača. Rezultati analize ukazuju da temperatura ispisa i podloge nema značajnijeg utjecaja na mehanička svojstva ispitivanih uzoraka.

ABSTRACT: This paper analyzes influence of the printing temperature and bed temperature on the mechanical properties of the tested samples. Temperature influence is the most important factor in the three-dimensional product printing. This is a reason why the printing production of bendy and stretchy test specimens has been shown, with the change of the printing temperature and the temperature of the printer bade. In experimental testing dimensional deviation of samples from the default parameters was determined during 3D printing, which is also the main deficiency of this type of printer. The results of the analysis indicate that the printing and bad temperature has no significant effect on the mechanical properties of the tested samples.
