“…Plastic formwork can also be a cost-effective solution, especially when recycled materials are used [5,32,35]. Labor costs are a major component of formwork costs [150,151]. These include the costs of assembling and disassembling the formwork, inspecting the formwork for safety, and repairing and maintaining the formwork.…”

This study provides a comprehensive review of the engineering challenges of formwork in concrete construction. The paper investigates different formwork systems, their design based on form pressure, and the difficulties of form stripping. Alternative binders are gaining more and more interest by opening new opportunities for sustainable concrete materials and their impact on form pressure and concrete setting is also investigated in this paper. The discussion involves several engineering challenges such as sustainability, safety, and economy, while it also explores previous case studies, and discusses future trends in formwork design. The findings pinpoint that choosing an appropriate formwork system depends significantly on project-specific constraints and that the development of innovative materials and technologies presents significant benefits but also new challenges, including the need for training and regulation. Current trends in formwork design and use show promising possibilities for the integration of digital technologies and the development of sustainable and ‘smart’ formwork systems. Continued research within the field has the possibility to explore new formwork materials and technologies, which will contribute to the implementation of more effective and sustainable practices in concrete construction.

“…Digital fabrication refers to data-driven production [8]. Digital fabrication technologies include both subtractive manufacturing such as Computer Numerical Control (CNC), additive manufacturing such as 3D printing, and robotic assembly of components [9][10][11]. It is believed that digital fabrication can "outperform the conventional construction over time" [3].…”

“…It can produce free-form panels quicker than the manual method. Silicon rubber is attached onto the CNC machine, and the bars move up and down to form the free-form shape [15,22]. In order to fabricate various forms of FCP, CNC equipment has been improved in order to develop the side form control system.…”

“…The method of measuring the errors was the conversion of the coordinates of engineered models into graphs or charts in order to compare the members with the engineered shapes. ANOVA analysis was conducted based on the average of the errors in order to test the reliability of the error analysis [15]. Furthermore, free-form concrete panel production technology was developed using CNC machines.…”

With the development of technology, the number of free-form structures—as well as their value—is increasing. In order to construct such free-form structures, a number of studies are being conducted on free-form molds from multifaceted perspectives. However, it is difficult to identify the progress of studies related to free-form molds, as the scope of the studies is redundant or similar in many cases. Therefore, the current study focused on the identification of the trends of preceding studies on free-form molds using the PRISMA technique. The study classified the studies into three topics in order to identify the trends: ‘free-form curve fabrication technology’, ‘free-form mold fabrication technology’, and the ‘analysis of free-form panel forms.’ Each topic was further categorized into two tiers for more in-depth analysis. The whole process was adopted in order to suggest the trends of studies on free-form molds. The findings are expected to be used to provide fundamental data for future studies on free-form molds, and to set the directions for new studies.
