+U ovom radu istraživan je utjecaj odabranih parametara FDM ispisa na mehanička svojstva 3D printanih uzoraka izrađenih od PLA materijala. Analizirani su parametri visine sloja, širine ekstruzije, postotka ispune, orijentacije slojeva i broja stijenki, dok su ostali uvjeti ispisa bili konstantni. Eksperimenti su provedeni prema Taguchijevoj metodi, a rezultati obrađeni ANOVA analizom. Utvrđeno je da orijentacija slojeva ima najveći utjecaj na vlačnu čvrstoću (23\% ukupne varijabilnosti), pri čemu su uzorci s paralelnom orijentacijom postigli prosječnu čvrstoću od 29,88 MPa u usporedbi s 21,94 MPa za okomitu orijentaciju. Broj stijenki pokazao je doprinos od 16,3\%, dok su ostali parametri imali manji utjecaj ($\leq$10\%). Kod smične čvrstoće najznačajniji faktor bio je postotak ispune (43,2\%), gdje je povećanje ispune s 20\% na 85\% rezultiralo rastom čvrstoće s 23,67 MPa na 34,13 MPa. Dobiveni rezultati potvrđuju da pravilnim odabirom parametara ispisa moguće značajno poboljšati mehanička svojstva 3D printanih komponenti te pružaju smjernice za optimizaciju FDM procesa u inženjerskim primjenama.

+\section*{Abstract}
+This thesis investigates the influence of selected FDM printing parameters on the mechanical properties of PLA specimens. The analyzed parameters include layer height, extrusion width, infill percentage, layer orientation, and wall thickness, while other printing conditions were kept constant. Experiments were conducted using the Taguchi method, and results were analyzed with ANOVA. The findings show that layer orientation has the greatest impact on tensile strength (23\% of total variability), with parallel layers achieving an average strength of 29.88 MPa compared to 21.94 MPa for vertical orientation. The number of walls contributed 16.3\%, while the effects of other parameters were below 10\%. For shear strength, the most influential factor was infill percentage (43.2\%), where increasing infill from 20\% to 85\% raised the average strength from 23.67 MPa to 34.13 MPa. These results confirm that proper selection of printing parameters can significantly improve the mechanical properties of 3D printed components and provide guidelines for FDM process optimization in engineering applications.

-U ovom radu istraživan je utjecaj odabranih parametara FDM ispisa na mehanička svojstva 3D printanih uzoraka izrađenih od PLA materijala. Analizirani su parametri visine sloja, širine ekstruzije, postotka ispune, orijentacije slojeva i broja stijenki, dok su ostali uvjeti ispisa bili konstantni. Eksperimenti su provedeni prema Taguchijevoj metodi, a rezultati obrađeni ANOVA analizom. Utvrđeno je da orijentacija slojeva ima najveći utjecaj na vlačnu čvrstoću (23\% ukupne varijabilnosti), pri čemu su uzorci s paralelnom orijentacijom postigli prosječnu čvrstoću od 29,88 MPa u usporedbi s 21,94 MPa za okomitu orijentaciju. Broj stijenki pokazao je doprinos od 16,3\%, dok su ostali parametri imali manji utjecaj ($\leq$10\%). Kod smične čvrstoće najznačajniji faktor bio je postotak ispune (43,2\%), gdje je povećanje ispune s 20\% na 85\% rezultiralo rastom čvrstoće s 23,67 MPa na 34,13 MPa. Dobiveni rezultati potvrđuju da pravilnim odabirom parametara ispisa moguće značajno poboljšati mehanička svojstva 3D printanih komponenti te pružaju smjernice za optimizaciju FDM procesa u inženjerskim primjenama.

-\section*{Abstract}
-This thesis investigates the influence of selected FDM printing parameters on the mechanical properties of PLA specimens. The analyzed parameters include layer height, extrusion width, infill percentage, layer orientation, and wall thickness, while other printing conditions were kept constant. Experiments were conducted using the Taguchi method, and results were analyzed with ANOVA. The findings show that layer orientation has the greatest impact on tensile strength (23\% of total variability), with parallel layers achieving an average strength of 29.88 MPa compared to 21.94 MPa for vertical orientation. The number of walls contributed 16.3\%, while the effects of other parameters were below 10\%. For shear strength, the most influential factor was infill percentage (43.2\%), where increasing infill from 20\% to 85\% raised the average strength from 23.67 MPa to 34.13 MPa. These results confirm that proper selection of printing parameters can significantly improve the mechanical properties of 3D printed components and provide guidelines for FDM process optimization in engineering applications.
