| Abstract | Over the past few decades, additive manufacturing (AM) has grown rapidly as a latecomer and is now an integral part of modern manufacturing industry. While additive manufacturing takes advantage of the incomparable advantages of traditional manufacturing methods, it always suffers from poor efficiency and scalability. Mobility and collaboration were introduced and validated by researchers to increase the flexibility of AM devices, effectively increasing the efficiency and scalability of this technology. Since then, it has become possible to conduct large-scale collaborative additive manufacturing with mobile AM devices. However, the combination of mobility and collaboration also places higher requirements on the positioning accuracy of AM devices. In large-scale collaborative additive manufacturing processes, more errors of all causes are more likely to arise than ever and lead to manufacturing failures, especially under uneven fabrication conditions. This research proposes some certain technical solutions, and analyzes in detail the causes and effects of various errors in large-scale collaborative additive manufacturing in three-dimensional space. According to the source of error formation, two error control concepts, "positioning error correction" and "leveling error correction ", are proposed. To verify the validity of the two concepts and corresponding strategies for large-scale collaborative additive manufacturing, a modular mobile 3D printer equipped with technical methods corresponding to the concepts was designed and developed. A set of experiments based on the laboratory environment was carried out to verify the error reduction effect of the developed device. The inspiration for the concept, the process of development, the design of the experiment and the result are described in detail in this paper. Ultimately, the developed device was shown to greatly reduce all of the potential errors during operation. This also means that the proposed concepts can be further generalized to various additive manufacturing technologies and better serve large-scale collaborative additive manufacturing. |
