Abstract

This study focuses on solving problems in traditional three-axis 3D printing, such as the stair-stepping effect, excessive support structures, and poor mechanical performance. It uses continuous carbon fiber as the printing material and designs an automated additive manufacturing system based on a KUKA multi-axis robotic arm. The study chooses a multi-degree-of-freedom robotic arm as the motion platform. It uses Solid Works to design and 3D print the printing structure, which includes a hot end, a cooling part, and a throat tube. To improve cooling, the system uses spiral cooling blades and compressed gas. For software, it uses Grasshopper to create visual printing paths. It controls the Marlin firmware through serial communication to automate the printing process. In final tests, the results show that the software makes the printing path clearer and flexible. It also improves system integration and printing accuracy. For the hardware, the new print head can print complex shapes. The cooling tower helps improve cooling. It prevents the continuous carbon fiber material from melting in the upper part of the throat tube. This avoids blockage in the material path.
