On February 10, 2025, according to the Resource Database, the United States International Codex Commission (ICC) recently announced that it will formulate the ICC 1150 standard, the first specification specifically for 3D 3D 3D 3D construction technology Automation (3dact). The standard will provide a complete set of structural standards for concrete walls printed in interior and exterior 3D, covering the applications of load -loading walls, non -loaded walls and shear walls, suitable for single -layer and multilayer structures.
The development of the ICC 1150 standard is underway through a consensual process recognized by the National Institute of Standards (ANSI), guaranteeing rigor, balance and transparency throughout the process. In January 2023, the members of the committee began to train to ensure that representatives of the industry involved have a wide variety. In July 2023, the ICC’s board of directors officially confirmed the list of committee members. The committee’s first call conference took place on October 20, 2023, marking the start of the standard establishment. The last meeting took place on October 11, 2024 and the committee approved a version project for a public exam by ANSI.
ICC 1150 standardThis is the first technical standard for 3D printed concrete walls, and it provides full structural specifications for interior and exterior applications. The introduction of this standard marks additional maturity and standardization of 3D printed concrete construction technology.
Currently, the public consultation project has been published and can be consulted in the “Management” section and in the form of public opinion of the ICC standard. The public examination period will start on December 13, 2024, with a deadline of January 27, 2025. The next committee meeting will take place on February 14, 2025, when public comments are again revised.
The introduction of this standard is an important step in the field of 3D -printed concrete construction, and it offers high guarantees to ensure the safety, reliability and innovation of buildings. Nevertheless, it should be noted that the International Organization for Standardization (ISO) previously published an international standard called “Adjustment The principles of manufacturing-qualification and infrastructure elements” (ISO / ASTM 52939: 2023). This standard mainly specifies standards, quality characteristics of 3D printing construction processes and factors related to additive manufacturing construction operations.
However, the scope of the application of the ISO / ASTM 52939: 2023 standard is relatively limited, mainly focusing on the construction process itself, and does not imply environmental, health and safety aspects such as the Definition of 3D printing installations, treatment of materials, packaging and transport of robots or operating equipment, etc., such as installing 3D printing installations, treatment of materials, Packaging and transporting robots or operating equipment. In addition, the standard does not cover key areas such as design approval, materials of materials, characterization and tests. Consequently, the introduction of the ICC 1150 standard fills this gap and provides more complete advice and specifications.
