Globally construction industry has highest carbon impacts which accounts for 40% of global energy consumption, 38% of carbon emission as well as 12% of water eutrophication. Thus, there is great demand for decarbonisation in this industry. 3D printing or additive manufacturing has emerged as a potential solution to reduce the energy demands, water wastage and carbon emissions. 3D printing in construction context is an innovative technology that creates 3D objects by reproducing physical objects with continuous layers. Recently, from polymer and steel the industry has leaped forward using concrete with potential applications in the construction engineering. Anecdotally, these technologies proved to reduce production time, minimise wastage and reduce labour costs significantly. The current challenges in 3D printing commercialisation, are lack of standard building codes, large scale investment, functional performance and architectural designs. In this research, concrete prototypes were printed for tests and a comparative study was established with the conventional manufactured concrete to analyse performance standards, cost benefits and lifecycle assessments. Future scope of this research is to develop a performance standards based on benefits for large scale implementation in construction industry.
