Abstract: Additive manufacturing (AM), commonly known as 3D printing, has evolved from a rapid prototyping tool into a viable manufacturing technology for functional parts across aerospace, biomedical, automotive, and consumer industries. The advancement of AM is strongly dependent on mechatronics integration, which combines mechanical systems, electronics, sensors, control algorithms, and software to achieve precise and automated fabrication processes. This paper presents a comprehensive review of mechatronics integration in additive manufacturing systems, focusing on hardware architecture, motion control, sensor feedback, intelligent process monitoring, and cyber-physical connectivity. It discusses the role of actuators, embedded controllers, and sensor fusion in improving print accuracy, reliability, and productivity. Emerging trends such as AI-assisted control, adaptive slicing, and digital twin-based AM are also analyzed. The study highlights benefits, technical challenges, and future research directions in achieving fully autonomous additive manufacturing platforms.
Keywords: Additive manufacturing, 3D printing, mechatronics integration, motion control, sensor feedback, cyber-physical systems, smart manufacturing
