| Abstract Scope |
Cooperative 3D printing (C3DP) is an emerging technology that addresses the scalability in size and printing speed in conventional 3D printers by employing multiple 3D printers working together. Accurate positioning and aligning between printers are critical for the success and quality of C3DP. In this study, we have developed a camera-based auto-calibration system for C3DP, which enables more precise and efficient printer calibration. The auto-calibration system utilizes computer vision with a camera that reads ArUco markers placed at known positions on the print bed. With the camera readings, the system accurately calibrates the kinematic parameters of the printers, ensuring the agreement between different printers on the markers' positions thereby spatially aligning them for C3DP. Our results show that this method significantly improves the calibration accuracy, achieving precision beyond 100 microns. In conclusion, the system provides confident printer alignment in C3DP, enhancing the overall efficiency and reliability of the C3DP process. |
