ABSTRACT This paper presents the design, development, and testing of a 3D-printed robotic manipulator, emphasizing the advantages of additive manufacturing in creating cost-effective, customizable robotic solutions. The manipulator includes key components such as a base, rotating section, shoulder arm, elbow arm, and end effector, all fabricated from durable ABS material. Actuation is achieved through a combination of MG996R and SG958 servos, along with a NEMA 17 stepper motor, controlled by an Arduino Uno microcontroller. The design process involved comprehensive research on existing open-source models, followed by iterative refinements using 3D modeling software. 3D printing utilized both ABS and PLA filaments, with material-specific settings optimized to ensure highquality output. The manipulator was tested to evaluate its precision, range of motion, and payload capacity. Results showed an average deviation of 0.7 cm in pick-and-place operations and a payload capacity of up to 500 grams. These findings highlight the manipulator's potential applications in manufacturing, assembly, and education, demonstrating the transformative impact of 3D printing on robotics. Future work will focus on enhancing the payload capacity and integrating advanced sensors to enable more sophisticated robotic functionalities.
