Technological developments certainly affect various industries. In industry 4.0, 3D Construction Printing is one of the technologies in the construction industry for house construction. This study aims to evaluate the advantages and disadvantages of the 3D Construction Printing method at the project site. The method of using 3D Construction Printing techniques is considered a promising alternative to traditional construction methods because it speeds up construction time, reduces labor, reduces construction waste, and also design flexibility. In this study, a scientific literature study will be conducted with a comparison of case studies. This case study was conducted on objects that became the first '3D Construction Printing buildings' from various countries based on differences in design, materials, and machines that are very different from one another. These case studies include Tecla, Wasp, Italy; Wujiazhuang, China; Autoconz, Yogyakarta; and Yhanova, France. The results of the analysis show that 3D Construction Printing tread houses have great potential in improving construction efficiency and reducing construction costs. This method can also result in more innovative and complex designs than traditional construction methods. However, this study also shows some challenges and risks that must be considered in the use of 3D Construction Printing tread houses. Some of the challenges include non-compliant construction regulations, lack of technical skills and knowledge in the construction industry, and issues with the availability of materials and printing technology. Risks associated with using 3D Construction Printing tread houses include damage to printing that results in structural errors, material quality and environmental resistance issues, and the inability to correct errors that occur during the printing process. Adjustments to the location also need to be considered between the material, and the type of machine used. The results of correspondence analysis show that the characteristics of technical aspects and development characteristics in the literature regarding 3D Construction printing have a significant correlation with 4 clusters. First, the relationship between design aspects (parametric, geometrical) with sustainable design, then the relationship of engines with energy effectiveness, research, emission reduction and duration. Third, construction aspects related to technology, sustainable development, efficient use of water. The economic aspect is related to waste treatment, ordinary materials, and sustainable materials. Overall, the study shows that 3D Construction Printing tread houses have great potential for use in the construction industry, but must be balanced with solving the challenges and mitigating the risks associated with their use.
