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,...

Stress-Guided Localized Infill Variation for Improving the Mechanical Efficiency of FDM-Printed L-Bracket Structures

Fused deposition modeling (FDM) enables spatial control of internal infill, but uniform infill neglects the nonuniform stress distribution governing failure. This study evaluates a finite element analysis (FEA)-guided, stress-based infill distribution strategy for FDM-printed L-b...
