ABSTRACT The rapid increase in waste electrical and electronic equipment (WEEE) poses a significant environmental challenge. To address this issue, initiatives promoting circular economy principles have emerged, such as utilizing recycled acrylonitrile butadiene styrene (ABSr) high‐impact polystyrene (HIPSr) from WEEE. This study evaluated the properties of virgin ABS (ABSv)/ABSr ABSv/HIPSr blends, with ABSr HIPSr obtained TV housing blend samples were prepared using filament extrusion, followed by either compression molding or 3D printing. ABSv exhibited stronger shear‐thinning behavior than at low shear rates, indicating higher content rubber. viscosities blends increased rates approximated those ABSv, ABSr, high rates. Overall, compression‐molded demonstrated superior impact strength compared to their 3D–printed counterparts.
