“…In despite of presently attempted, the current construction is in need for large scale 3D printers to build complex geometric shapes on projects where construction time, cost, and quality are the predominant and determining success criteria [17]. In accordance, a novel approach for 3DCP technology for on-site construction, named CONPrint3D, is currently being developed at the TU Dresden, Germany, which intends to bring 3DCP directly into the building sites [15].…”

Several researchers have worked in the field of implementing robotics technology in concrete building construction, after the first attempt in the 1980s in Japan. Various motivations such as the shrinking labor population, the aging of skilled workers, and the construction safety issues have promoted the development of such technologies. However, the future visionary on how construction robots can transform the concrete building construction sector is still not solid nor well structured. What really needs to be changed? What types of construction activities can be taken by automated robotic technologies, as opposed to manpower or skilled worker? To answer these questions, the systematic review reported in this paper seeks to evaluate and synthesize empirical findings on the use of robotic technologies in concrete building construction. A systematic search of Scopus, Web of Science, IEEE, and Engineering Village databases was conducted, and 48,200 documents were targeted. By applying the inclusion and exclusion criteria, 48,149 records were excluded, and the remaining 51 records were assessed for eligibility and included in the qualitative synthesis. The systematic review shows that researchers in the USA played a leading role on robotics in concrete building construction, followed by Germany and Switzerland. The robotics application and techniques have been largely used on-site and targeted low-rise buildings. The robotic technologies that have been popular in literature included 3D printers, and swarm robotics. Most of the papers have proposed a limited novel structural design, without introducing innovative construction material. Even though the direct and indirect construction activities related to formwork, steel reinforcement, and concreting can be replaced and thus eliminated, the horizontal RC elements still cannot be built on-site without supports. Moreover, rapid prototyping found to be the best robotic design for the purpose of building construction through utilizing manipulator robots.

“…There are numerous advantages to this technology, including cost and time savings, fewer pollutants, and a reduction in casualties. According to Teizer, et al (2016), the construction sector has lately effectively implemented industrial uses of the technology in a variety of domains, including consecutive layers of concrete. Furthermore, 3D printing's core idea is that the 3D volume is reduced in the computer to large-scale printing of complicated geometric shapes in a sequence of 2D layers.…”

3D printing has been popular in the manufacturing industry as a means of automating processes, speeding up production, and reducing waste. It is frequently seen as a relatively new technology, even though it has been in use for more than three decades. This article aims to analyse 3D printing awareness in an emerging economy towards sustainability in the construction industry. A survey research design was used to obtain primary data from the respondents using structured questionnaires. The sample frame for the research survey comprises professionals in construction and consultancy firms such as architects, quantity surveyors, projects managers, and engineers. Mean item score, standard deviation, and factor analysis were used to analyse the data. The findings from this study show that majority of the professionals acknowledged that they were aware of the existence of 3D printing, but most of them attested that they had not utilized this technology before the survey. The study reveals that the professionals in the construction industry of the emerging economy have low awareness of 3D printing technology, therefore its practices in the construction industry of the study area are significantly low. More awareness of 3D printing technology should be raised by bodies shouldered with management and regulation of the construction industry to increase professionals' awareness and enlighten them on the benefits of adopting the technology towards sustainable construction.

“…They offer freedom of shape because of the powder bed process, combined with high surface quality without significant layer lines. They are, however, limited by machine build volume, and the addition of reinforcements is not possible during the process (Teizer et al , 2016).…”

Purpose This paper aims to focus on the evaluation of a polymer concrete as a three-dimensional (3D) printing material. An associated company has developed plastic concrete made from reused unrecyclable plastic waste. Its intended use is as a construction material. Design/methodology/approach The concrete mix, called PolyBet, composed of polypropylene and glass sand, is printed by the fused deposition modelling process. The process of material and parameter selection is described. The mechanical properties of the filled material were compared to its cast state. Samples were made from castings and two different orientations of 3D-printed parts. Three-point flex tests were carried out, and the area of the break was examined. Computed tomography of the samples was carried out. Findings The influence of the 3D printing process on the material was evaluated. The mechanical performance of the longitudinal samples was close to the cast state. There was a difference in the failure mode between the states, with cast parts exhibiting a tougher behaviour, with fractures propagating in a stair-like manner. The 3D-printed samples exhibited high degrees of porosity. Originality/value The results suggest that the novel material is a good fit for 3D printing, with little to no degradation caused by the process. Layer adhesion was shown to be excellent, with negligible effect on the finished part for the longitudinal orientation. That means, if large-scale testing of buildability is successful, the material is a good fit for additive manufacturing of building components and other large-scale structures.
