3D Printing Technology in Construction (2019-05)¶

The purpose of this paper is to study the introduction of 3D-printing of concrete in the construction sector. A survey was conducted to collect professional view on ongoing innovations in the construction sector, including 3D-printing. Participants were selected among the members of Norwegian networks for project and construction management research. The survey highlighted effective leadership, collaboration with partners and industry-academia collaboration as primary enablers of innovation. Few of the respondents to the survey have used 3D-printing technologies. It is difficult to obtain representative samples in this type of research, including this study. The study can be seen as a snapshot of attitudes in the sector. 3D-printing appear as a potentially interesting technology, especially for unstandardized construction components. Further work is needed to materialise the expectation for technological development in the construction sector. Most research on 3D-printing has focused on demonstrating technical potential. This study adds a practitioners’ perspective, with a large dose of pragmatism.
