Thin-walled structures are of great interest because their use as lightweight components in aeronautical and aerospace engineering. The fabrication these by additive manufacturing (AM) often produces undesired warpage the thermal stresses induced process components’ reduced structural stiffness. objective this study is to analyze distortion several thin-walled fabricated Laser Powder Bed Fusion...

This paper reviews the shape distortions in a polymer composite, its sources, characterization techniques, and remedies. The distortion may include warpage, spring-in, or change enclosed diameter for flat, angled, circular parts. Residual stresses are considered to be major source of (dimensional instability) laminated composites. These result difference thermal expansion behavior different pli...
