Crashworthiness experimental and multi-criteria decision-based evaluation of fused filament fabrication 3D-printed PLA tubular structures with varying infill architectures
The purpose ofthis study is to quantify how infill geometry affects the crashworthiness of fused filament fabrication (FFF) 3D-printed polylactic acid (PLA) tubular structures subjected to axial compression, with the aim of identifying an infill pattern that maximizes energy management and deformation stability....
