“…Apis Cor was the first company to develop a mobile 3D printer for the construction industry that comprised a rotating truss on a central base. It claims to have successfully printed a 37 m 2 house on site in 24 h [13]. The Apis Cor has a maximum operation area of 132 m, with an 8.5 m reach from the central manipulator and a maximum height of 3100 m. The printer uses the same cement mixture for printing foundations and walls, thereby reducing material waste.…”

“…However, previous studies have failed to fully introduce and investigate replacements for steel, particularly from a practical perspective. In situ 3D printing has the potential to cut transport costs, energy consumption, and pollutant emissions, as well as injuries and fatalities [13]. However, such potential benefits should be evaluated in the contexts where they are critical to practitioners.…”

Three-dimensional (3D) printing technologies are transforming the design and manufacture of components and products across many disciplines, but their application in the construction industry is still limited. Material deposition processes can achieve infinite geometries. They have advanced from rapid prototyping and model-scale markets to applications in the fabrication of functional products, large objects, and the construction of full-scale buildings. Many international projects have been realised in recent years, and the construction industry is beginning to make use of such dynamic technologies. Advantages of integrating 3D printing with house construction are significant. They include the capacity for mass customisation of designs and parameters to meet functional and aesthetic purposes, the reduction in construction waste from highly precise placement of materials, and the use of recycled waste products in layer deposition materials. With the ultimate goal of improving construction efficiency and decreasing building costs, the researchers applied Strand 7 Finite Element Analysis software to a numerical model designed for 3D printing a cement mix that incorporates the recycled waste product high-density polyethylene (HDPE). The result: construction of an arched, truss-like roof was found to be structurally feasible in the absence of steel reinforcements, and lab-sized prototypes were manufactured according to the numerical model with 3D printing technology. 3D printing technologies can now be customised to building construction. This paper discusses the applications, advantages, limitations, and future directions of this innovative and viable solution to affordable housing construction.

“…In the past 20 years, the development of niche research on 3D printing in construction and automation flourished. In the international, here are a non-exhaustive name such as Contour Crafting, 3D-P (MIT) in United State, Winsun in China, D-Shape from Italy, CyBe Construction from the Netherlands, COBOD International from Danemark, Vertico from the Netherlands, Apis COR from Russia and XtreeE from France [17][18][19]. These niches have flourished but there are still major issues in the regulation of the material used in 3D printing for construction.…”

The objective of this paper is to propose a pre-experimental framework of printability pre-assessment of cementitious materials. This study firstly presents a general review of additive manufacturing in construction and then examines the main characteristic of the material formulation and printability properties based on extrusion technique. This framework comes with experimental tests to determine a qualitative printability index of mixtures. It uses mix-designs reported in the literature to define interval ratio of mixture design to be investigated in this study. The focus was put on two criteria that influence the formulation namely flowability and buildability. Two practiced based tests, mini slump and cone penetrometer, were used to draw the flowability and buildability dimensionless index. The results were analyzed by introducing an optimal printability coefficient and examining their time evolution. An optimal time of printing was determined Toptimal. Finally, a 3D mortar printing system and its operational process are presented. Then, based on the measurement, the optimal mixture is identified and printed in a large-scale geometry.

“…Some scholars thought that C3DP shortened the construction duration and reduced the labor cost and material waste [2,5]. In particular, the cost of formwork is reduced, because C3DP technology does not need to use formwork [6,7].…”

It is controversial that the cost of construction 3D printing is lower than the conventional construction in academic field. The reason is that some scholars have confused attributes between construction 3D printing and traditional construction. The cost calculation of construction 3D printing cannot follow the rules in conventional construction because construction 3D printing was identified as both industrial product and construction product. This paper proposed a new approach to cost calculation of construction 3D printing concerning both the properties of industrial and construction product. The cost elements and calculation methods of onsite and offsite 3D printing were discussed and concluded. The comparison of cost composition among conventional construction, onsite construction 3D printing, and offsite construction 3D printing was presented as well. The paper put forward the idea of cost calculation about industrialized construction, and it solved the problems of cost calculation among different construction technologies.
