In recent years,the advances in robotics have broken the limitations of printing position for the traditional 3D printers.The motion mode with multiple degrees of freedom has more flexible printing track and richer mechanism design.Taking the 3D printing mechanical structure based on Stewart parallel mechanism as the research object,the specific size of the parallel mechanism was determined,the structure of the main frame of the 3D printer was designed,the 3D model of the mechanism platform was established with Solidworks,and its motion trajectory was analyzed.The model was imported into Matlab for kinematics simulation analysis,and Ansys was used for statics analysis.This study can provide six degrees of freedom motion at the material bearing end,providing a reference for the subsequent development of multi-degrees of freedom printers.
