In this study, a sample part is manufactured by using the Powder Bed Fusion (PBF) method with maraging steel metal powder, and the manufactured part is examined in terms of dimensional accuracy by image processing techniques. The sample =art is drawn with various geometric shapes so that dimensional and areal controlling with the image processing techniques can be performed accurately. The purpose of dimensional control is to choose the most suitable manufacturing parameters to ensure the closest production of the real dimensions of the part. With the detection of significant deviations in dimensional values by image processing techniques, the designs of the part should be changed according to these deviations. In this study, each layer of the manufactured sample part image is captured by a camera. Afterward, dimensional and areal percent error rates are determined by three different methods based on image processing techniques.
