Bridging innovation and practice: assessing the readiness for 3D printing in construction

摘要

Purpose This study investigates the factors that influence 3D printing technology adoption in the construction industry, with a focus on the economic, environmental, social and regulatory barriers to widespread integration. Despite the widely acknowledged potential of 3D printing to transform construction practices by lowering costs, increasing efficiency and enhancing sustainability, adoption has been slow. The research focuses on the economic, social, environmental and regulatory factors. Design/methodology/approach The literature review discusses both the benefits – such as lower labour costs, faster construction times and less material waste – and the drawbacks – such as high initial costs, reliance on traditional methods and a lack of standardized regulations. A quantitative research methodology was used to investigate these issues, which included distributing a structured survey to 150 construction industry professionals. The survey’s purpose was to collect detailed quantitative data on 3D printing perceptions, preferences and experiences. The data were analysed with SPSS software using descriptive statistics, correlation analysis and reliability testing, which provided a thorough understanding of the factors influencing 3D printing adoption. Findings The study concludes with actionable recommendations to address these challenges, such as advocating for increased government support through subsidies and incentives, investing in training and education to reduce resistance to change and developing standardized regulations to ensure the safe and effective implementation of 3D printing. These strategies, which are consistent with the literature, are required for the construction industry to fully realize the benefits of 3D printing technology, ultimately increasing productivity, lowering costs and contributing to more sustainable construction practices. Research limitations/implications This study has several limitations. The sample size was modest and geographically limited, which may restrict the generalizability of the findings to broader construction contexts. Additionally, some survey constructs demonstrated low internal reliability, suggesting the need for more refined measurement tools in future studies. The cross-sectional design also limits the ability to assess changes in perceptions over time. Despite these limitations, the study provides important insights into the economic, social, environmental and regulatory barriers to 3D printing adoption. The findings offer practical implications for industry stakeholders, policymakers and researchers seeking to advance innovation within the construction sector. Practical implications The findings of this study provide actionable insights for construction industry stakeholders seeking to adopt 3D printing technologies. Addressing economic challenges through financial incentives, training and partnerships can enhance feasibility, particularly for SMEs. Environmental benefits such as material efficiency and reduced waste should be leveraged to support sustainable practices. Policymakers must develop clear regulatory frameworks to streamline approvals and ensure safety. Training programmes and awareness campaigns are essential to overcome social resistance and skill gaps. By addressing these areas, industry professionals and decision-makers can accelerate the responsible integration of 3D printing and drive innovation in construction processes. Social implications The adoption of 3D printing in construction carries significant social implications, particularly in workforce transformation and public acceptance. While the technology may reduce demand for manual labour, it creates opportunities for skilled jobs in digital design, robotics and machinery operation. This shift highlights the urgent need for reskilling and upskilling programmes. Additionally, public perception plays a crucial role; concerns about safety, reliability and job displacement can hinder adoption. Raising a
