In this study, the effect of fiber presence in continuous fiber reinforced Fused Deposition Modeling samples (FDM) on the stress and residual strain created during the process was investigated. The FDM process has become one of the most widely used Additive Manufacturing methods for layered prototypes from a three-dimensional model. One of the most important issues in this process is the distortion of parts produced during printing. The distortion created is mainly due to the rapid cycles of melting and solidification of the material, which produce residual stresses in the sample. The main objective of this study was to measure the residual strain rate of residual stress in unreinforced and reinforced PLA samples with continuous fiber using digital image correlation and hole drilling technique. Digital imaging is one of the novel non-contact optical methods for measuring displacements, detecting defects and investigating the properties of components. Among the various optical methods, digital image correlation is superior to other optical methods due to its low cost, high speed and no need for phase analysis. According to the results, the maximum strain in the fiber reinforced specimen in the x and y directions was 1.09 and 0.34%, respectively. The strains released in the reinforced specimen were higher than other specimen at all stages of drilling.
