摘要

Polymer-ceramic composites based on acrylonitrile butadiene styrene (ABS) and styrene-butadiene-styrene (SBS) with titanium dioxide (TiO2) and strontium titanate (SrTiO3) fillers were successfully developed and processed into filaments for fused deposition modeling (FDM) 3D printing of microwave components. The structural, mechanical, and dielectric properties of the composites were systematically investigated. Among the studied formulations, the ABS-40 wt% TiO2 composite was identified as the most promising, exhibiting a well-balanced combination of dielectric permittivity (ε ≈ 8.1), low dielectric loss (tan δ ≈ 0.02 at 3 GHz), and enhanced mechanical strength compared to neat ABS. These results highlight the potential of ABS-TiO2 composites for lightweight, mechanically robust, and microwave-transparent components such as dielectric lenses, antenna radomes, and electromagnetic windows.
