Manufacturing transforms raw materials into finished products through various processes, including machining, forming, and additive techniques. It plays a crucial role in producing goods for diverse industries, driving economic growth and technological innovation , additive manufacturing, particularly fused deposition modeling (FDM), has revolutionized the fabrication process of robots by enabling rapid prototyping and customization. In this study, we focus on the design and defective analysis of a robotic arm fabricated using polylactic acid (PLA) material via FDM technology. However, despite advancements in FDM technology, defects such as warping, layer misalignment, and voids may occur during fabrication, affecting the robot's overall quality andfunctionality. To address these challenges, a comprehensive defective analysis is conducted. This involves inspecting the fabricated robot for common defects using visual inspection, microscopy, and non-destructive testing techniques. Key design considerations include optimizingforPLA'smaterial properties,suchasitsstiffness,tensilestrength,densityandimpactstrength,toensurethe roboticarm’s performance. The results of this study contribute to the advancement of additive manufacturing methodology in manufacturing robotics, facilitating the development of cost-effective, customizable, and high-performance robotic systems for various applications with less defects
