【Abstract】 On the basis of analyzing 3D printer working mechanism deeply, the 3D printer extrusion mechanism was designed and improved based on full consideration of the issues on the printing speed and precision of workpiece. The novel three jets extrusion mechanism model was established. The virtual design was performed using three-dimension modeling software to obtain the optimal design model. After the performance comparison analysis, the designed extrusion mechanism met the design requirement, which provided an effective solution for improving printing speed and workpiece forming accuracy.更多还原
