Design and Application Research on Control System of 3D Printer Based on Multi-DOF Robotic Arm

This study combined 3D printing technology to design a control system for a small robotic arm and developed a compact and multi-degree-of-freedom robotic arm 3D printer.Firstly, the forward kinematics and inverse kinematics of the manipulator are solved in detail, and then the path is interpolated to realize the high-precision trajectory planning of the manipulator.This robotic 3D printer can perform complex 3D printing tasks with precision.The research focuses on optimizing the motion trajectory of the manipulator to ensure the stability of motion and the precision of printing.The results show that the system significantly improves the dynamic response and print quality of the printer, makes the printing attitude more flexible, and expands the diversity of printed products.This research aims to improve the traditional 3D printer to achieve a multi-purpose machine, improve work efficiency, and reduce costs.Under the background of "New Engineering Course", combining theory with practice can improve engineering practice ability and scientific research innovative thinking.
