ABSTRACT This study investigates the potential applications of nanocomposites formed by integrating novel materials such as multi‐walled carbon nanotubes (MWCNT), titanium nitride (TiN), and cubic boron nitride (c‐BN) with UV resin. The objective is to explore their utilization in modern manufacturing technologies, emphasizing the development of multifunctional composites. This research addresses a critical gap where current composite materials often fail to meet the stringent performance demands for advanced electronic and magnetic applications, particularly at high frequencies. To ensure homogeneity, MWCNT, TiN, and c‐BN nano powders were thoroughly mixed with the resin. Subsequently, stereolithography (SLA) technology was used to manufacture WR‐284 electromagnetic samples from these mixtures. The results demonstrate that the 1% MWCNT sample enhances magnetic permeability ( μ ′) to values above 1.08 at higher frequencies and significantly reduces dielectric losses, with the imaginary part ( μ ″) reaching positive values up to 0.07. Similarly, the 1% c‐BN sample shows a high and stable increase in magnetic permeability, with μ ′ values consistently above 1.05 and μ ″ values reducing energy loss to 0.06. These findings highlight the balance between energy storage and dielectric losses across different modified samples, offering valuable insights into their potential applications. This study fills significant gaps in our understanding of material science and paves the way for innovative industrial applications, particularly in areas requiring efficient magnetic field propagation and minimal energy loss.
