This study designed and implemented a novel parallel decoupled manipulator with the aim of enhancing the quality and efficiency of 3D printing. By optimizing the structure of the manipulator, the surface quality problem caused by the support structure in traditional 3D printing was solved, and the printing precision and stability were improved. This manipulator module is suitable for the v25 printer, adopts a delta design, has three degrees of freedom, and meets technical indicators such as the maximum printing size, positioning accuracy, printing speed, and working precision. The research contents include mechanism selection, 3D modeling, kinematic analysis, and trajectory planning. During the process of mechanism selection, the characteristics and applicability of various parallel mechanisms were comprehensively considered, and finally the most suitable structural form for 3D printing needs was determined. Through accurate 3D modeling, the visual design of the manipulator was realized, providing a basis for subsequent analysis and optimization. In terms of kinematic analysis, the motion characteristics and laws of the manipulator were deeply studied to ensure the accuracy and reliability of its motion. In the aspect of trajectory planning, a reasonable motion path was formulated to improve the printing efficiency and quality.
