Abstract Scope |
Cooperative 3D Printing (C3DP) is an emerging additive manufacturing paradigm where multiple robotic 3D printers work cooperatively to fabricate large parts. Accurate execution of C3DP requires not only the precise calibration of each individual printer, but also spatial alignment across multiple printers—a process that is often manual, slow, and error-prone. In this paper, we present a camera-based method for calibrating the XYZ axes of cooperative 3D printers using ArUco fiducial markers placed at known reference positions and a basic monocular camera. By comparing observed marker coordinates with their known locations, the system successfully calibrates kinematic parameters of individual printers and across printers. This ensures consistent positioning across all of the printers, achieving the spatial alignment necessary for C3DP. Experimental results validate the effectiveness of the method in achieving accurate, repeatable multi-printer calibration, supporting the reliable execution of C3DP jobs. |
