Overview

Randomized trial optimizes mechanical performance in PLA/PLA-CF composites, suggesting effective production improvements.

Key Points

  • This research aims to enhance the mechanical reliability of PLA and PLA-CF composites by optimizing FDM process parameters.
  • Studied PLA and PLA-CF sandwich structures using the Taguchi L9 orthogonal array for optimization.
  • Achieved maximum tensile strength of 47.9 MPa, Young’s modulus of 1526 MPa, and elongation at break of 5.19%.
  • Performed analysis of variance (ANOVA) to identify the significance of process parameters.
  • Optimum parameters included concentric infill, 0.1 mm layer height, and 150 mm/s printing speed.
  • Infill pattern accounted for 36.1% of load-bearing capacity variation and 34.2% of stiffness variation.
  • Confirmed Taguchi model with R² = 94.74% and significant mechanical performance enhancement (p = .029).
