Analysis of the dielectric strength of selected materials produced using 3D printing technology

<ns3:p>This publication presents the results of dielectric strength tests conducted on selected materials. The methodology for sample fabrication is described, utilizing two different spatial printing technologies. The tested samples were manufactured from four materials with varying properties: PLA, ABS, PA12, and a recycled material (e-PLA). Significant differences in dielectric strength were observed, both among the individual materials and between the applied manufacturing technologies. It was determined that samples made of PA12, produced using laser sintering (SLS) technology, exhibited the highest dielectric strength. The objective of the study was to evaluate the feasibility of producing insulating components for power transmission and distribution lines through dielectric strength testing. Preliminary results indicate that, with the appropriate technology and material selection, this manufacturing approach may be a viable alternative for such applications.</ns3:p>
