Impact of Blending and Temperature Variation on the Compressive Properties of 3D Printed Recycled ABS

The use of recycled acrylonitrile butadiene styrene plastic (RABS) in conjunction with virgin acrylonitrile butadiene styrene (VABS) in fused filament fabrication (FFF) 3D printing has appeared as a promising method to enhance material properties and promote sustainability. This study investigates the impact of varying printing temperatures on the compressive strength of 3D printed samples fabricated from RABS/VABS blend (0/100, 100/0, 90/10, 80/20, 70/30, 60/40, 50/50). The results demonstrate that the compressive strength of the blend is significantly influenced by the printing temperature, with the optimal temperature being 240°C. Additionally, the study reveals that the sample fabricated using RABS/VABS blend ratio of 60:40 sample along with 240 ⁰C print temperature showed improvement in compressive modulus, strength at yield and strength at maximum load by 11.2, 15.6 and 19.45%, respectively. These findings underscore the potential of RABS/VABS blend in 3D printing, offering a sustainable and effective solution for producing high-performance components.
