A REVIEW ON 3D PRINTING OF CONCRETE - THE FUTURE OF SUSTAINABLE CONSTRUCTION.

The objective of the present paper is to present a critical review on 3D printing types of concrete, developments in 3D printing of Concrete, legal aspects, current challenges, and future perspectives of 3D printing of concrete. Though there are many challenges, in future, Concrete printing is believed to have the capacity to change or improve the traditional construction process to some extent. Designers and architects need to understand the benefits of this technology in terms of improved design features and hence should be able to unleash their design potentiality that was previously restrained by traditional construction methods.
