Establishing Research Methods for 3D Concrete Printing Supply Chain Studies (2025-11)¶

As digital construction technology, 3D printing is reshaping the construction sector by reducing costs and improving efficiency. Its supply chains differ from traditional models and require redesign. However, research on enhancing supply chain efficiency in 3D concrete printing remains limited. Building on a previous systematic review conducted as part of the PhD study, this study discusses research methods, data collection techniques and analysis methods, and establishes a research methodology for developing a practical supply chain decision-making tool in 3D printing construction. It follows the systematic review findings to design the research program, integrating theoretical knowledge with practical applications. The study also reviews research methods to identify suitable approaches for data collection and analysis, as well as outcome validation. The results presented a comprehensive research design for developing the decision support tool. This research connects systematic review and data analysis, enabling a coherent interpretation of the overall research program. The final outcomes are expected to improve 3D printing projects’ efficiency, facilitate the adoption of the technology in the construction sector, aligning with SDG 9, promoting inclusive and sustainable industrialization.
