Experimental investigation and COPRAS-based selection of FFF-printed double-walled polygonal conical structures for crashworthiness applications

This study presents a comprehensive experimental investigation into the crashworthiness performance of thin-walled, double-walled polygonal conical structures fabricated via Fused Filament Fabrication (FFF) using enhanced polylactic acid (PLA+) material. The influence of the cross-sectional geometry (square, hexagonal,...

Experimental investigation and optimization of 3D-printed circumferentially corrugated multi-cell polygonal structures

This study aims to investigate the crashworthiness of 3D-printed multi-cell thin-walled polylactic acid plus (PLA+) tubes under quasi-static axial compression. The objective is to explore the influence of inner geometry, radius application and diameter variations on crashworthiness indicators and to identify optim...

Experimental Investigation and Multi‐Response Optimization of Crashworthiness Performance in 3D ‐Printed Thin‐Walled Tubes

This study investigates how geometric configurations and manufacturing parameters affect the crashworthiness performance of tubes printed by fused deposition modeling (FDM) using polymer filaments. Three distinct cross‐sectional geometries are evaluated using the standard polylactic acid (PLA), PLA PRO1, and carbon...
