“…The C3DP also improved the buildability, functional integrity, and accuracy of construction [6,7]. Bos et al [8] and Hager et al [9] believed that C3DP could reduce the cost of construction techniques to a great extent. Yingchuang, a high-tech enterprise of C3DP in Shanghai, China, claimed that C3DP could save 30 to 60% of construction materials and shortened 50 to 70% of construction duration while the labor cost could be reduced by about 50 to 80% [6].…”

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.

Additive manufacturing (AM), also known as 3D printing, produces components by building-up structures from small deposits of materials. Many of the early applications of AM technologies have been in the aerospace, automotive, and healthcare industries. Building on the advances in AM in these industries, there are several experimental applications of AM in the construction sector. Early investigations suggest that use of AM technologies for construction have the potential to decrease labour costs, reduce material waste, and create customized complex geometries that are difficult to achieve using conventional construction techniques. However, these initial investigations do not cover the full range of potential applications for construction or exploit the rapidly maturing AM technologies for a variety of material types. This paper provides an up-to-date review of AM as it relates to the construction industry, identifies the trend of AM processes and materials being used, discusses related methods of implementing AM, and potential advancements in applications of AM. Examples of potential advancements in methods and applications include multi-material use (e.g., use of high-performance materials only in areas where they are needed), in-situ repair in locations that are difficult or dangerous for humans to access, disaster relief construction in areas with limited construction workforce and material resources, structural and non-structural elements with optimized topologies, and customized parts of high value. AM's future in the construction industry is promising, but interdisciplinary research is still needed to provide new materials, new processes, faster printing, quality assurance, and data on mechanical properties before AM can realize its full potential in infrastructure construction.

“…The bridge has been designed, starting with the capabilities of the 3D concrete printer at TU/e in mind. The facility has been described by Bos et al (2016). Despite the fact that the full bridge coincidentally fits in the current print box, it was decided not to print it in one piece from the bottom to the top of the deck, but instead in multiple elements that need to be assembled.…”

“…The cross-section exists of a (curved) top and (straight) bottom flange that combined with the prestress force (Bos et al, 2016), indicating the direction parallel to the print in the horizontal plane, perpendicular to the print direction in the horizontal plane, and vertically perpendicular to the print direction (or parallel to the robot arm), respectively. provides the bending moment resistance.…”

“…To be able to develop the conceptual design into a final design, the (structural) material properties of the applied print mortar Weber 3D 115-1, globally described by Bos et al (2016) (and since been given its trade name), had to be established. Obviously, this custom designed material does not comply with standard concrete designations (C30/37, etc.).…”

The current state of research and development into the additive manufacturing of concrete is poised to become a disruptive technology in the construction industry. Although many academic and industrial institutions have successfully realised full-scale structures, the limitations in the current codes of practice to evaluate their structural integrity have resulted in most of these structures still not being certified as safe for public utilisation and thus deemed as test prototypes for display purpose only. To realise a 3D concrete printed (3DCP) structure which could be certified safe for public use, a bridge was realised using the print facility of the Eindhoven University of Technology (TU/e) based on the concept of 'Design by Testing'. This paper holistically discusses the complications encountered while realising a reinforced 3DCP bridge in a public traffic network and decisions taken to find solutions for overcoming them.
