Requirements analysis of additive manufacturing for concrete printing - A systematic review

The acceptance of concrete printing as a viable construction method is limited because of a lack of expertise and due to the heterogeneous and non-standardized nature of additive manufacturing (AM) data modeling, affecting the reliability and the interoperability of the concrete printing process. To advance standardization of AM data modeling in concrete printing, information exchange requirements must be defined along the digital thread, i.e. the digital workflow that transforms 3D models into printed components. In this paper, a requirements analysis of AM for concrete printing is conducted through a systematic review. The AM process for concrete printing is defined, identifying information exchange requirements. Sources relevant to AM and concrete printing are systematically reviewed, collecting and analyzing attributes of the information exchange requirements for concrete printing. As a result, the requirement analysis serves as basis to standardize the digital thread, in an attempt to advance reliability and interoperability of the concrete printing process.
