“…For example, it can be peat blocks that can be mixed for different parts of construction with ceramic blocks, foam concrete, gypsum, sandwich panels, which are also reasonable to obtain using recycled raw materials. Besides, one can apply 3D printers to create buildings using recycled construction waste as raw materials, which will substantially reduce the cost and time of creating structures, and the technologies have already been described and tested by international companies [8].…”

The disposal of construction waste, the amount of which is constantly growing due to hostilities in Ukraine and outdated housing stock that has lost its consumer properties is an acute problem. The study proposes adopting the circular economy and the principles of improving the security and environmental situation in Ukraine to restore the country’s potential. The article analyzes the main stages and processes of construction waste disposal, taking into account their fractional recycling and reuse in the reconstruction of settlements, which is based on the rational use of resources and innovations and will reduce the cost of restoring destroyed settlement areas. Efficient construction is possible only if environmental and economic indicators are improved, the level of safety and manufacturability are improved. A methodology for assessing the effectiveness of future construction has been developed and recommendations for its improvement have been given.

“…The cost reflective construct includes, C1: "Profit margin improvement", C2: "Cash flow enhancement", and C3: "Reduction in variable costs". It is found that profit margin improvement is the ultimate benefit of adopting 3D construction printing, and with respect to Khoshnevis, Pan et al, and Shahzad et al [55,57,59], it is also found to be reliant on making the construction project successful. The cost of production is already prone to being one of the critical advantages of 3D construction printing, as is evident from the outcomes of this study.…”

“…Many authors have produced overviews of this technology and its consequences and uses in construction, and the number of these publications is growing. Shahzad et al, Mascarenhas and Makhoul, and Kazemian and Khoshnevis [55][56][57] stated that, while these analyses cover a wide range of topics, they often zero in on one facet of technology and how it is used. However, the present level of study lacks the systematisation necessary to offer a full overview of the technology's uses and influence in the residential building sector of developing nations such as Malaysia.…”

After a decade of research and development, 3D printing is now an established technique in the construction sector, complete with its own set of accepted standards. The use of 3D printing in construction might potentially improve the outcome of the project as a whole. However, traditional strategies are often used in the residential construction industry in Malaysia, which causes serious public safety and health issues along with a negative impact on the environment. In the context of project management, overall project success (OPS) has five dimensions, such as cost, time, quality, safety, and environment. Understanding the role of 3D printing in relation to OPS dimensions in Malaysian residential construction projects would allow construction professionals to adopt 3D printing more easily. The aim of the study was to find the impact of 3D construction printing on OPS while considering the implications for all five dimensions. Fifteen professionals were interviewed to first evaluate and summarise the impact factors of 3D printing using the current literature. Then, a pilot survey was conducted, and the results were checked using exploratory factor analysis (EFA). The feasibility of 3D printing in the building sector was investigated by surveying industry experts. Partial least squares structural equation modelling was used to investigate and validate the fundamental structure and linkages between 3D printing and OPS (PLS-SEM). A strong correlation was found between 3D printing in residential projects and OPS. Highly positive implications are indicated by the environmental and safety dimensions of OPS. Malaysian decision-makers may look to the outcomes of introducing 3D printing into the residential construction industry as a modern method for increasing environmental sustainability, public health and safety, reducing cost and time, and increasing the quality of construction work. With this study’s findings in hand, construction engineering management in Malaysia’s residential building sector might benefit from a deeper understanding of how 3D printing is used for improving environmental compliance, public health and safety, and project scope.

“…But with the current technology, people can not integrate a high-performance hardware to such a small scale, so for a period of time, people still need to produce large graphics display cards to meet the demand. However, in the future, with the development of science and technology, this resource consuming thing will gradually disappear [9].…”
