Diffusion of Innovation: A Systematic Literature Review of 3D Printing in Construction

This study assesses the adoption of 3D printing technologies in construction, focusing on materials, printer types, and broader trends. It examines key barriers and drivers influencing industry adoption. Relevant studies from academic databases and industry sources were selected based on technological and economic aspects, including journal articles, conference papers, and industry reports resulting in the analysis of technology and material use, adoption trends, as well as barriers such as cost, regulatory challenges, and technical limitations, alongside drivers like sustainability demand and automation advancements. Findings show the adoption of the technology remains in the early stages, with uneven implementation across markets and different target markets. The study evaluates the pace of adoption and recommends strategies to accelerate the integration of 3D printing in construction. These include workforce re-skilling, enhanced government incentives, and cost-reduction initiatives. The study concludes that while 3D printing technologies hold immense potential to revolutionize construction, further effort is required to overcome technical, regulatory, economic, and social barriers for widespread implementation.
