| Abstract Scope |
Additive manufacturing continues to evolve through the development of screw-based extrusion systems capable of processing pellet based refined thermoplastic material with improved deposition control and material throughput. Among these materials, acrylonitrile butadiene styrene reinforced with carbon fiber (ABS-CF) has gained attention due to its enhanced mechanical strength, thermal resistance, and lightweight properties. However, limited research exists regarding the behavior of screw-based printing systems when depositing ABS-CF on non-planar or angled printing surfaces. The objective of this study is to investigate the print quality, material flow behavior, and dimensional consistency of screw-based extrusion printing using ABS-CF on both planar and angled surfaces. The research evaluates how surface orientation affects layer adhesion, extrusion stability, and geometric accuracy during the printing process. Experimental testing is conducted using a screw-driven extrusion additive manufacturing setup with controlled print parameters including nozzle temperature, extrusion rate, and print angle |
