Abstract. The limitations of traditional construction methods can be addressed by 3D printing, a technology that prints structural buildings in layers, which reduces labor, construction time, wastage of material, and the overall cost of the structure. This paper presents a literature review of the state-of-the-art of construction using 3D printing technology. We present a definition and a

very limited. After sketching the potential of AMoC for construction, this paper introduces the variants of AMoC under development around the globe and goes on to describe one of these in detail, the 3D Concrete Printing (3DCP) facility of the Eindhoven University of Technology. It is compared to other AMoC methods as well as to 3D printing in A new data center building under construction in Heidelberg, Germany, is set to be Europe's largest 3D-printed structure. The technology shows promise, but challenges to its widespread adoption

Other methods for 3D printing include powder binding and additive welding. Powder binding is 3D printing within a basin of powder, solidifying powder layer-by-layer to create the desired object. Additive welding has been demonstrated by printing a full-scale, functioning metal bridge in Amsterdam. Benefits and challenges. Faster construction

The current and potential role of 3D printing in the imperative fight against COVID-19 is also discussed. Moreover, the major challenges and developments in overcoming those challenges are addressed. This document provides a cutting-edge review of the materials, applications, and challenges in 3D and 4D printing technologies. Then, the implemented technologies and construction methods for the 3D printed small-size bridges (i.e., pedestrian and biking bridges) in different countries are discussed. Finally, the limitations and challenges and the future directions of construction 3D printing in bridge construction are highlighted.
challenges of 3d printing in construction
The global 3D printing building construction market is expected to grow from $0.01 billion in 2021 to $0.02 billion in 2022 at a compound annual growth rate (CAGR) of 177.0%. The growth is mainly
In this context, 3D printing technology appears to be the key solution to building and construction problems. 3DP enables engineers to build complex structures using computer aided design in a short time without the need of formwork or extra-workers [1]. 3D printing, also known as additive manufacturing, is widely utilized in many industries
the various 3D-printing manufacturing systems developed so far can be found in Duballet et al., 2017. Although the technologies discussed in this paper are often referred to as ‘concrete 3D printing’, a more accurate description is ‘cementitious materials 3D printing’. The development of various cementitious However, a successful application of AMoC in architecture needs to consider the possible constraints and limitations of concrete 3D printing. So far, research on the potential challenges of applying AMoC in architecture from a building lifecycle perspective is still limited. The study results of this study could be used to improve design and
As an example of Industry 4.0 in a project context, 3D printing of concrete has the potential to provide a paradigm shift for construction processes with significant implications for project management. This study investigates and reports the enablers and barriers of implementing the innovative 3D printing technology in construction projects
Despite highly diverse applications of 3D printing and new advancements in 3D printing, there are still a few challenges that restrict the usage of 3D printing on a commercial scale. These include the resistance and adaptability of 3D-printed material’s properties and structures against the change in environmental factors, such as temperature
With quicker construction times, reduced labor costs and less material waste, 3D printing offers a potential solution to many construction challenges. While it is still a relatively new technology, the advancements being made are paving the way for more efficient and sustainable construction techniques.
The growth of 3D printing in construction. As 3D printing advances speed up in developing societies, certain aspects of the plan are more poised for progress than others. 3D printing of concrete. Concrete is definitely one of them. In fact, the large-scale 3D printing industry is expected to be worth $68.4 million by 2023.

The 3D data file of The Radiolaria Pavillon, designed by architect Andrea Morgante was added to the D-Shape is a large-scale particle-bed 3D printing process for ephemeral shell, uploaded in the computer, converted into STL-format building construction developed by Dini [12, 13].

The results address two aspects of 3D-printing in construction. The first aspect is about present and expected degree of implementation, while the second aspect is about expected cost issues. 4.1. Implementation of 3D-printing. The questionnaire addressed the use and implementation of 3D-printing.
Lessons learnt for metal 3D printing in construction from additive manufacturing using other materials and in other industries are also presented. Winsun Dubai office building [30] Castilla-La

Global construction industry for construction 3D printing(3DP) is a novel technique that has started since 3DP innovation in 1981 while still, this technique has undergone a challenge in Indonesia and Malaysia's construction industry. Applying 3DP in the construction industry has given various benefits more than the conventional construction way.

This paper aims to review, summarize, analyze, and introduce the research progress of ML applications in construction 3D printing, followed by a discussion of the current challenges and future research scope. Firstly, the classification and working principle of 3D printing and ML technology were introduced.
