Abstract

Variations in process parameters in Fused Deposition Modeling (FDM) often lead to differences in the tensile strength of Polylactic Acid  (PLA)  materials. However,  results  reported  in  previous  studies  remain  inconsistent  and difficult  to compare  directly.  This condition  makes  it  challenging  to identify  which  parameters  have  a  truly  significant  effect  on tensile strength.  This  study  aims to  analyze  the influence  of  FDM  process parameters  on  the  tensile  strength  of  PLA materials  using  secondary data  consisting of  74  observations,  which  were  organized  into  a structured  dataset  and analyzed using descriptive statistics and correlation analysis. The results show that print orientation has the strongest negative correlation, with a value of −0.51, indicating that an increase in print orientation is associated with a decrease in tensile strength. Layer height also shows a negative correlation of −0.38, where smaller layer thickness is associated with higher tensile strength. Nozzle temperature exhibits a positive correlation of 0.35, while print speed does not show a significant effect on ultimate tensile strength (UTS). This approach enables a faster and more systematic identification of the most influential parameters compared to reviewing individual studies separately. Therefore, this study provides a  clearer  understanding  of  parameter  prioritization  in  the  FDM  process,  which  can  support  more  efficient  decision-making to improve the tensile strength of PLA materials.
