This study used shredded ABS waste (RABS) and continuous brass wire (CBW) to create 3D-printed composites via the FDM and in-nozzle impregnation technique. The composites’ properties were analyzed through dynamic mechanical analysis (DMA). X-ray diffractometry (XRD) revealed the amorphous nature of the materials, with VABS exhibiting key peaks at 13.6⁰ and 20.2⁰. DMA results demonstrated that CBW reinforcement significantly enhanced the stiffness and thermal stability of the composites. Sample S5, with the highest brass wire content, achieved the maximum storage modulus (2900.5 MPa) and loss modulus (765.67 MPa), while S3 showed optimal performance in stiffness and damping for product design applications.
