Table 5: Outcomes from the study. context, materials such as PLA, ABS, ASA, PETG, and PC/ABS, which are currently used or have potential as electrical insulators, were selected. The breakdown strength of the solid insulating materials produced via 3D printing were measured in the high-voltage laboratory in accordance with IEC-60243 standards. The Weibull distribution of the results obtained from the breakdown strength tests was assessed. Additionally, a detailed damage analysis of the breakdowns in the test specimens was conducted using ImageJ software. The interpretation of the information obtained as a result of the study will determine the level of contribution to the literature. In this context, when looking at the data in Table 5, it is possible to say that the superficial damage ratio exhibits a similar behavior as the breakdown strength. As the high voltage applied to the material increases during experimental studies, the effect created by the electric arcs bridging between the layers of the material naturally increases. This shows that the breakdown strength of the material is high. In addition, it also reveals the effect of layered production on the breakdown strength, which occurs with 3D printing. The damage rate in the PLA material was 0.03%. Thus, the maximum breakdown strength of the material was measured as 24.82 kV/mm. The maximum breakdown strength of the PETG material was measured as 28.73 kV/mm, and the surface damage rate on the material was determined as 0.72%. Thus, the relationship between the damage rate and breakdown strength was determined. Another result obtained from the study is that the ASA material presents an exceptional situation. The breakdown strength and surface damage rate are outside the behavior of other materials. As a result of the Weibull statistical distribution analysis, the voltage value at which the solid insulation material will be punctured with 95% probability was obtained. In the simulation study, the value of the maximum electric field intensity caused by the electric field irregularity occurring at the electrode edges was determined. When these two values are compared, the similarity of the experimental studies and the simulation study can be compared. While it is predicted that the ABS material will be punctured with 95% probability at 34 kV/mm, it is seen that it is exposed to a maximum electric field intensity of 33.74 kV/mm in the simulation study. The difference between the two values is calculated as 0.75%. While it is predicted that the PC/ABS material will be punctured with 32 kV/mm, it is determined that it is exposed to a maximum electric field of 33.04 kV/mm. The difference between these two values is calculated as approximately 3.25%. In this context, the effective role of the simulation study is revealed when evaluating the breakdown strength of solid insulation materials. As seen in the image processing analysis studies carried out in Section 4.2, during the puncture, the electric current moved in the direction of the printing of the filaments.
