This study presents an analysis of the distortions of ABS composites with different amounts of carbon fiber produced by large-scale additive manufacturing (LSAM). Part failures often occur in extrusion-based large-scale additive manufacturing due to thermal contraction. These are called thermal distortions. Undesirable distortions are caused by differential thermal expansion and contraction and corresponding residual stresses. Residual stress and strain analysis require accurate thermo-mechanical material properties. These can be controlled by changing the amount of additives in polymer material. In this study, fiber orientations in Acrylonitrile Butadiene Styrene (ABS) reinforced with 10%, 5%, 0% carbon fiber by weight were modeled using a homogenization technique. The amount of distortion of the parts modeled according to these carbon fiber ratios was examined and, the cooling durations were compared.
