Review meeting of CCPA standards Specification for 3D Printable Concrete Premix and Technical Requirements for 3D Concrete Printing Equipment was held by CCPA and CBMF on April 28, 2025. 41 representatives from research and architectural design institutes, colleges and universities, industry associations, inspection body and laboratory, production enterprises and users attended the meeting, of which 15 were members of review committee.

The main drafter of the two standards introduced the standard preparation process, the collection of comments and the test data that support the main technical requirements in the two standards respectively. The review committee reviewed all the documents, examined the standard text word by word and put forward revisions. The review committee made conclusions that technical indexes of both the two standards are advanced and applicable and they both reach domestic advanced level in general. Finally, the two CCPA standards were approved by unanimous approval.

Specification for 3D Printable Concrete Premix specifies the raw materials, quality requirements, test methods and inspection rules for 3D printable concrete premixes, etc. The implementation of this standard is of great significance for improving the production and application quality of 3D printable concrete premixes.

Technical Requirements for 3D Concrete Printing Equipment stipulates the general technical conditions for 3D concrete printing equipment, aiming to provide scientific and comprehensive technical guidance for the research and development, production and application of 3D concrete printing equipment. It strives to promote the digital upgrade of the entire chain from architectural design, material preparation, printing construction to finished product acceptance through high-precision technical standardization. The implementation of this standard will strongly drive the transformation of the implementation mode of 3D concrete printing technology towards a more innovative and efficient direction, providing technical support for 3D concrete printing equipment technology.
