Utjecaj interne strukture važan je čimbenik pri trodimenzionalnoj izradi modela budući da određuje stabilnost i kvalitetu izrađevine. Upravo zbog toga je prikazana izrada rasteznih i savojnih ispitnih tijela uz promjenu određenih parametara izrade zbog promatranja utjecaja interne strukture na svojstva. Detaljnije, visina sloja i količina ispune su mijenjane kroz petnaest različitih serija izrađenih na prostornom uređaju Prusa i3. Prikazom rezultata i analizom utvrđeno je ponašanje izrađevine u odnosu na postavljene parametre.

The impact of the internal structure is an important factor in the development of three-dimensional models since it determines the stability and quality of the product. For that reason, test specimens made for tensile and flexural properties are presented in this thesis. In order to observe the impact of internal structure on the properties, the production parameters were variable. More detailed, layer height and fill density were modified through fifteen different series made on three-dimensional device Prusa i3. The results of the analysis showed the behavior of the product in relation to the specific parameters.
