Abstract:The technology of 3D concrete printing (3DCP) is rapidly evolving over the past years. In a relatively short period, the technique has proven its first real civil project in the form of a small bicycle bridge in Gemert. As the technology becomes more mature and increases in technological readiness levels (TRL), other aspects within 3DCP become more relevant. An important aspect of what is still challenging for the innovative technique is legislation. Since the developments are still strongly in development and many research institutes are printing in its own manner and legislation is early to think about setting standards. Discrepancy research has been done to map where are still the challenges in order to reach a complete standard that covers every aspect. To set the first forms of pre-standards (that serves as handles for regulation), it is important to create a broad-based consensus. A uniform agreement should contain experts in the field of academic, industrial and governmental perspective. Also, since concrete printing deviates on almost every aspect, new additional standards should be written regarding concrete mix design, structural design, and execution design. All categories should contain some form of technical recommendation in order to ensure the quality of the printed structure. This research resulted in a roadmap that describes the safety phases for 3D concrete printing. The results of this study emphasize the need for standardization of scientific test methods, sharing knowledge and the will to work together. These points determine the speed of the development of regulation for 3DCP
