###### Abstract
Dissipation factor measurement was performed to investigate the effects of the applied aging method. The measurement results showed that polycarbonate samples performed better than kraft paper samples [24]. Moreover, increasing the temperature value resulted in higher dissipation factor values for all solid insulating materials, thus emphasizing the negative effect of temperature on the materials. In another comparative study conducted to determine an alternative insulator to kraft paper to be used in transformers, kraft paper, polyphenylene sulfide (PPS), polycarbonate (PC) and PET materials were subjected to electrothermal aging at 90 \({}^{\circ}\)C, 110 \({}^{\circ}\)C and 130 \({}^{\circ}\)C temperatures, and 4 kV/mm electric field for 2 months. The dielectric constant, dielectric loss factor and dielectric strength of aged samples were measured. Dielectric strength did not always show a change in the same direction with aging for each material. Partial discharge inception voltage (PDIV), which is one of the partial discharge parameters, is an important parameter for interpreting the partial discharge behavior of insulator materials. Measurement and diagnostic methods traditionally employed for high-voltage insulators have been extended to analyze materials fabricated using next-generation 3D printing technologies, enabling comprehensive performance evaluations. In the study by [PERSON] et al., planar capacitors were fabricated using 3D printing with Acrylonitrile Butadiene Styrene (ABS) as the base polymer. The research investigated the impact of nanofillers, specifically zinc oxide (ZnO) and copper-carbon nanotubes (Cu-CNT), on the dielectric and conductive properties of ABS composites [25]. In [26], test specimens were fabricated using 3D printing with Acrylonitrile Butadiene Styrene (ABS) as the polymer matrix filled with Barium Titanate (BT) microparticles. The dielectric performance of the ABS-BT composites was evaluated by measuring the relative permittivity over a frequency range of 250 Hz to 200 kHz. In the study by [PERSON] et al. [27], the dielectric and thermal properties of several polymers suitable for Fused Filament Fabrication (FFF) were evaluatedfor electronic applications through dielectric constant, breakdown strength, and volume resistance. The results showed that PETG and ABS-T stood out for their balance of cost and dielectric performance. On the other hand, in [28], the dielectric properties of 3D-printed objects made from PLA, ABS, and PET-G were evaluated, focusing on the effects of printing resolution. Measurements included relative permittivity, dissipation factor, and dielectric strength. The results showed that higher printing resolutions generally improved dielectric strength, particularly for PET-G and PLA. Furthermore, ABS demonstrated the highest dielectric strength among the materials tested, while PET-G exhibited the highest relative permittivity but with poorer printability at high resolutions. In [29], the dielectric properties of PLA and High Impact Polystyrene (HIPS) were investigated at low frequencies (10 Hz to 100 kHz) with varying infill percentages (20-100%). The results showed that higher infill percentages led to increased permittivity values for both materials, with a dose-response relationship between infill percentage and permittivity. PLA exhibited higher relative permittivity compared to HIPS, but both materials demonstrated potential for use in electrotechnical applications with proper infill optimization. In this study, a capacitor design with a value of 1 nF that can be used in high-voltage laboratories and can operate at a nominal voltage of 10 kV was realized. In capacitor production, the 3D printing method was used, as it stands out with its economical and fast design processes and is thought to be useful as it is a practical production method tailored to the needs. A 3D printer was utilized for producing both insulating and conductive materials. PLA, ABS, ASA and PETG were employed as insulating materials.
