A ROADMAP TOWARDS ADOPTION OF 3D PRINTING IN CONSTRUCTION INDUSTRY OF DEVELOPING COUNTRIES

Abstract

Pace of development and progress in construction industry of developing countries is very low as compared to developed countries. Use of automation in construction is inevitable for development of construction industry so that it can meet the housing and accommodation requirements of rapidly growing population. 3D Printing is one of the emerging automation technologies in construction. A plethora of research has been carried out to assess the current state of 3D printing in construction industry worldwide and to identify the key benefits and barriers towards adoption of 3D printing in building & construction industry. The study aims at developing a roadmap towards adoption of 3D Printing in construction industry of developing countries. A detailed survey is carried out to identify the key benefits and barriers towards adoption of 3D printing in construction industry. Customized designs, uniqueness in façade & reduction in construction time are identified as key benefits while key barriers are identified as lack of codes & guidelines and unavailability of suitable materials. A detailed data collection is performed for collection of a set of recommendations to optimize the effect of benefits and barriers. The recommendations from industry experts are used for development of a roadmap which will help in successful adoption of 3D printing in construction industry of developing countries. Continuous research & development, awareness campaigns & seminars and involvement on government level are suggested as the top strategies for successful adoption of 3D printing in construction.
