Additive manufacturing of concrete in construction: potentials and challenges of 3D concrete printing

Abstract

Additive Manufacturing (AM) of raw materials like concrete, appeared as one of the most effective emerging technologies in the construction sector. The primary aim of this technology centralized over the minimization of supply chain difficulties, as the adoption of the technology made the construction industry autonomous in the area of building material production, directly by the aid of the digital models. The world population is exceedingly growing which exerts pressure on various sectors including construction.The AM-based 3D printing of the Concrete utilized the designing on digital platforms, which developed the aspect of high customizability with infinite boundaries. Digital designing made the development of the structure possible that fulfilled the requirement of the situation or the client. The technology is bespoke without any additional resources or machinery. The study work will elaborate on the dimension of AM of concrete in the construction sector and illustrate the potential and challenges.3D printing of the concrete is associated with the development of the structures and shapes, on-site construction leading towards the decentralization of manufacturing, followed by the construction and construction. 3D Printable concrete is one of the emerging trends in the construction sector. This trend developed on the core of Additive Manufacturing (AM), under which the concrete is designed by pumping through a nozzle connected to a “Gantry Grider” The movement of the nozzle is directed by the user or manufacturer, leading towards the development of the 3D Concrete model. The development of 3D Printable Concrete is a major potential and benefits discussed in the research studies about the AM of Concrete or 3D printable concrete.
