Abstract

Additive manufacturing (AM), commonly known as three-dimensional (3D) printing is a group of emerging techniques for fabricating 3D structures directly from a digital model in successive layers. The American Society for Testing and Materials (ASTM) defines AM as “the process of joining materials to make objects from 3D model data, usually layer upon layer” [1]. AM technologies were initially developed in the 1980s and have already been successfully applied in a wide range of industries including aerospace and automotive manufacturing, biomedical, consumer, and food [2]. Currently, AM techniques have become an integral part of modern product development. 3D printing technology is gaining popularity in construction industry. Unlike the conventional approach of casting concrete into a formwork, 3D concrete printing (3DCP) combines digital technology and innovative insight from materials technology to allow freeform construction without the use of expensive formwork. Freeform construction would enhance architectural expression, where the cost of producing a structural component will be independent of the shape, providing much-needed freedom from rectilinear designs [3]. When compared to conventional construction processes, the application of 3D printing techniques in the construction industry may offer excellent advantages, including: (1) reduction of construction costs by eliminating expensive formwork [3,4]; (2) reduction of injury rates by eliminating dangerous jobs (e.g., working at heights), which would result in an increased level of safety in construction [3]; (3)
