Robot-Based 3d Printing: Digital Twin-Driven Motion Planning Platform

Digital Twin (DT) technology can build the twin model of physical objects in a virtual environment, enable the perception of physical objects through simulation technology, and carry out simulation and evolution in the virtual environment. By simulating the behavior of physical objects, the process of motion can be judged, analyzed, predicted and optimized. For large-scale 3D printing, the challenges of kinematic planning, support design and extrusion material melting need to be addressed. In this paper, a digital twin-driven robot-based 3D printing architecture is proposed, which can realize multi-angle printing and reduce the support of the model by using the nozzle at the end of the robot. With the support of digital twin technology, the real-time data interaction between the physical robotic arm and the virtual one is realized. Finally, a numerical example is given to verify the feasibility and accuracy of the architecture.
