The main interest in terms of the geometrical analysis of this study lies in identifying the irregularities in the printed samples. The method for determining the inner diameter of the samples through image analysis relies on assessing the cylinder's adherence height to the cone. This method allows for the identification of the contours on both the left and right sides of the cylinder, which are situated between the top and bottom corners. After the inner diameter is calculated, the deviation of the inner diameter from the expected diameter (∆D i ) is calculated with an equation similar to Equation .
