Optimization of FFF parameters for enhanced tensile and shear strength of PLA + parts and mechanical performance of porous scaffolds
Fused filament fabrication (FFF) is widely used to produce polymer-based parts, particularly bioscaffolds, though mechanical performance depends heavily on process parameters. In the present study, a Taguchi L9 orthogonal design is used to examine the influence of printing angle, infill percentage, and layer thicknes...
