Factors Affecting 3D Printing Technology Adaptation in Construction (2021-02)¶

Three-dimensional (3D) printing in construction technology has rapidly developed in recent years and is being implemented on a prototype basis for relatively small building and bridge construction projects. A number of 3D printing-based solutions are still at the laboratory experiment stage. Thus, understanding how to adapt 3D printing successfully is still one of the challenging issues facing the construction industry. Although the innovative literature provides clues about potentially relevant factors for construction 3D printing technology adaptation, research has still not specifically addressed this topic. This knowledge gap hampers further advancements in 3D printing for construction, launching new products, and the development of related services for the industry. Hence, as a response to the aforementioned shortcomings, this paper reveals nine potential factors and thirty-two of their measurements that determine the decision to adapt 3D printing technology for construction projects. To quantify the influence of the relevant factors and measurements, the structural equation modeling technique was employed. The results indicate that the top significant factors in ensuring the success of 3D printing technology in construction are “technology compatibility,”“supply-side benefits,” and “complexity.” Based on these findings, current and future 3D printing project managers may utilize the results of this study to guide their efforts in adapting this technology to produce high-value construction components and related products and to generate new business opportunities.
