Additive manufacturing has revolutionized the production of polymeric parts with its capability to produce complex geometries with customized properties. Due to the characteristics of semi-crystalline polymer materials, they are being produced widely using additive manufacturing processes. However, warpage is a major challenge in semi-crystalline polymer materials, and it can significantly impact dimensional accuracy and overall part quality. For 3D printed parts to have accurate dimensions, structural integrity, and functional performance, warpage in materials must be understood and controlled appropriately. In this study, the warpage behaviour of 3D printed short carbon fibre-reinforced nylon matrix composite is numerically investigated using the DIGIMAT commercial package software. A parametric study of the effect of fibre reinforcement is conducted. The robustness and accuracy of the presented computational approach are validated with literature and extended to parametric studies.
