Abstract
Three-dimensional (3D) printing is a procedure used to create 3D objects in which consecutive layers of a material are computer-controlled produced. Such objects can be constructed in any shape using digital model data. First, this paper presents a state-of-the-art review of the advances in 3D printing processes of construction. Then, the architectural, economical, environmental, and structural features of 3D printing are introduced. Examples of 3D printed structures are presented, and the construction challenges facing Jordan, that encouraged this study, are stated. Finally, a precise description regarding the impact of 3D printing is provided by comparing conventional construction data of Ras Alain Multipurpose Hall in Jordan and the expected data if the same building has been built using 3D printing. The suggested model is generated using Revit software. As a result of this study, an understanding of 3D printing procedure, mechanism of action, and its impact on the future of construction and architecture through economical, structural, and environmental parameters is achieved. This leads to encourage engineers and contractors to take this subject into account for construction in Jordan.
Highlights
Researchers studied different types of 3D printers, materials, and construction procedures to take this technique forward to construct structural components and/or whole structure [3]
Is paper presents a state-of-the-art review of the advances in 3D printing procedures. e investigation of the impact of 3D printing is applied by comparing the concrete cost of conventionally built Ras Alain Multipurpose Hall in Jordan with the cost if it was built using 3D printing. e suggested model is generated using Revit software
The material cost of concrete is considered for the comparison. e saving of construction time is verified by the examples presented in Section 4. e saving is due to the continuous work of the printer over the days with a rate of three minutes per square meter [34]. e construction time saving is not quantified in this paper since this paper focuses on the design alteration and the material cost saving
Summary
Using the CC procedure, the installment of steel reinforcement into each layer is designed as shown in Figure 4(a) [14]. A segment of pipe can be placed and attached through the constructed conduit (after applying several wall layers) onto the lower segment that is already installed (Figure 4(c)). A simple robotic arm can grab these pieces and connect it to the component already installed while printing the wall (same as the plumbing procedure) (Figure 4(d)). Recycled glass aggregates and basalt were tested to improve the construction for sustainable structures [4]. Ties were manually placed between layers, while the machine was applying the concrete wall form. Ree-points bending test was conducted on a straight 3D printed reinforced concrete RC beam. Two key stages were identified based on the measured load-deflection
