Construction technologies have received increasing attention in recent years, especially 3D printing technology implementation in modern construction projects. As a disruptive construction technology, 3D printing has benefits in efficiency improvement and waste and emission reduction. However, there are limitations to implementing 3D printing technology in the construction industry. Previous research focused more on technology development rather than supply chain management problems in the newly developing industry. Therefore, the proposed research aims to address management issues in supply chain management for the 3D printing construction industry in New Zealand. The ongoing research initiative is advancing steadily, and this proposal delineates the research background and objectives, outlines the proposed methodology, and forecasts potential findings. The study’s goal is to develop a decision support system to assist the project management team in effectively managing the supply chain, specifically internal operations management in 3D printing construction companies. A mixed methods research methodology will be applied, using qualitative and quantitative methods as a whole. A systematic literature review will be the start to study existing research focuses, 3D printing implementations, research methods, and research gaps. Qualitative analysis will employ grounded theory, a case study, and site visits to identify practical challenges and justify the feasibility of research outcomes. Quantitative analysis will adopt life cycle assessment (LCA), surveys, and secondary data analysis, which aims at quantifying management performance, practitioners’ viewpoints, and environmental impacts. As a result, the outcome will hopefully facilitate the sustainability of supply chain in New Zealand’s 3D printing construction companies.
