Experiment-based distortion prediction model for wire-based additive manufactured parts

In this study, an experiment-based distortion prediction model for wire-based additive manufactured (AM) parts is proposed. Based on the assumptions for predicting the longitudinal bending distortion in inherent strain theory, the experiment-based distortion prediction model for wire-based AM parts was defined. Subsequently, an experimental study was designed based on the defined assumptions, which were validated through experiments. Consequently, based on these assumptions, a shell element-based elastic finite element (FE) approach was applied to the wire-based AM parts. The proposed experiment-based distortion prediction model was in good agreement with the validation case studies. In addition, the feasibility of a fast simulation approach for wire-based AM parts using the elastic FE approach was demonstrated. Based on these results, it was concluded that the proposed model can be applied for fast deformation predictions of AM structures.
