Abstract

The global construction industry faces mounting pressure to innovate for sustainability and efficiency, with 3D concrete printing emerging as a transformative technology. Despite its potential, significant challenges such as technological immaturity and insufficient policy support hider widespread 3DCP adoption. Drawing on lessons from the adoption of Building Information Modeling in the United States and Hong Kong, this paper addresses these policy gaps by developing a conceptual framework that facilitates 3D concrete printing adoption.

Through a systematic review of 30 publications and a qualitative content analysis, this study identifies and synthesizes 17 key policy factors across six policy dimensions into a comprehensive framework. The findings underscore the critical role of sustainability, transformative technical development policies, and research and development initiatives in accelerating 3D concrete printing adoption. Additionally, the study highlights a policy shift from profit-driven strategies to eco-innovative and socio-environmental entity as the technology matures, particularly in its early development stages.

The proposed conceptual policy framework provides actionable strategies for policymakers and industry stakeholders to address existing barriers and accelerate the widespread adoption of 3D concrete printing. A critical insight suggests that governments leadership, along with a shift to business models based on usage rights rather than ownership, could reduce financial burden on end users. This coordinated approach combining government leadership, targeted R&D support, eco-innovative policies, and new business models can establish 3DCP as a sustainable and scalable solution for future construction needs.
