Factors Affecting Acceptance of 3D Printing in Construction
Abstract:
3D printing is believed to be the technology of the near future. It is an innovative method offering cost reduction, time saving and limited emissions when compared with conventional methods. For example, a three-bedroom house printed by Apis Cor last December costed just over $10,000. In comparison, a similar house built by Habitat for Humanity costs roughly $50,000. With cost of building being one-fifth of what it was, those who are below the poverty line may find affordable housing. All such benefits could make the 3D printing technology a potential game changer for construction industry in the near future. However, there are some challenges facing the future of 3D printing. The sustainability of printed buildings is unknown, and the testing of materials as well as procuring the equipment is a costly endeavor. Government safety regulations for 3D printed buildings do not exist. Lastly, the impact on the labor force and the economy is still unknown. It is important to investigate these issues to determine the overall impact of 3D printers on construction industry.
To resolve such issues, research is required to understand the impact of 3D printing on construction industry. Through an extensive literature review covering 3D printing in manufacturing, construction, energy and others, this work identifies financial, economic, social and risk related factors that could impact acceptance of 3D printing in construction. A detailed qualitative analysis will be presented that has enabled ranking the critical factors influencing industry and end user acceptance.
