Standardization Aspects of Concrete 3D Printing

Digital fabrication with concrete has the potential to contribute to sustainability as a resource-efficient construction method. However, the absence of standardized testing, processing and approval procedures hinders the widespread adoption of 3D printing in concrete construction. The need for uniform testing procedures and processing requirements is crucial to overcome the complexities, lengthiness, and costliness of current construction processes, ultimately promoting the quality and reliability of 3D printed structures. This paper examines the current state of development, identifies gaps in existing standards, and proposes initial steps towards European-level standardization.
