Multi-Objective Optimization of Mechanical Properties for FDM-Printed PLA/TPU Blends via Box–Behnken Design and Entropy Weight Method
Polylactic acid (PLA) is widely used in fused deposition modeling (FDM) due to its excellent mechanical properties and processability. However, its inherent brittleness significantly restricts its application in load-bearing and high-toughness scenarios. To address this limitation, this study establishes a multi-object...
