The Implementation and Development of 3D Concrete Printing for On-Site Applications in Construction

Abstract

Construction innovations are developing in an increasing number of applications around the world. Of the proven innovations, Additive Manufacturing (AM) has been found as a staple process which demonstrates immense potential across manufacturing and industrial applications. Yet, it has not found its place in the construction field. The construction industry has been slow to adopt many emerging innovations since the early tech era. However, it has demonstrated recent adoption tendencies among specific design and management application. For a construction application of AM, 3D Concrete Printing (3DCP) revitalizes a new hope for increased productivity, customization and sustainability options while reducing construction costs, construction time, manpower and potential hazard exposure. At the current stage of development, 3DCP is encountering numerous technical challenges and field considerations for applications on and off construction sites. It is the aim of this thesis to examine integration factors of this innovative technology into the construction sector while exploring the potential impacts and outcomes of 3DCP as that groundbreaking technology. Based on a review of literature surrounding the 3DCP practice as well as the industry sector, interviews were conducted on partners active in an ongoing research project seeking to develop the next generation of 3D concrete structures. Analysis of the responses aim to provide a basis of understanding for the technology's performance, industry adoption and on-site integration of 3D printers. Thus, this exploratory study seeks to compile the internal and external considerations to provide initial research into the adoptability of a promising technology.
