ISO/ASTM published a new standard (ISO/ASTM 52939: 2023) regarding the use of additive manufacturing in construction works using 3D printing technology

This method basically explains about the quality guidelines and requirements for additive construction processes employing 3D printing technology. This standard aims to ensure the consistency, reliability, and safety of structures produced through additive manufacturing, offering a framework for quality management throughout the construction life cycle. The current method is applied on all additive manufacturing technologies in building and construction, structural and infrastructure building elements for residential and commercial applications.

  1. Material Standards:
    • Specifications for materials suitable for additive construction.
    • Quality requirements for construction-grade additive manufacturing materials.
  2. Process Control and Calibration:
    • Guidelines for precise control and calibration of 3D printing processes.
    • Parameters for ensuring the repeatability and accuracy of printing equipment.
  3. Structural Quality Assurance:
    • Criteria for evaluating and ensuring the structural integrity of 3D-printed constructions.
    • Non-destructive testing methods and performance metrics.
  4. Safety and Environmental Standards:
    • Identification and mitigation of safety risks associated with additive construction.
    • Adherence to environmental sustainability principles in the construction process.
  5. Documentation and Traceability:
    • Requirements for comprehensive documentation of the 3D printing and construction processes.
    • Traceability standards for materials, processes, and quality control measures.

Quality Management System

ISO/ASTM 52939:2023 encourages the establishment of a robust quality management system for additive construction. This includes:

  1. Process Audits:
    • Regular audits of additive construction processes to ensure compliance with standards.
    • Continuous improvement initiatives based on audit findings.
  2. Training and Certification:
    • Guidelines for the training and certification of personnel involved in additive construction.
    • Ongoing professional development to stay abreast of technological advancements.

Certification and Compliance

Manufacturers, contractors, and stakeholders are encouraged to comply with ISO/ASTM 52939:2023 to demonstrate a commitment to quality and safety. Certification processes may be established to verify conformity with the standard.

ISO/ASTM 52939:2023 provides a pivotal framework for ensuring the quality and reliability of structures built using additive construction techniques. Stakeholders in the additive manufacturing and construction industries are urged to adopt and implement the guidelines outlined in this standard to foster innovation while maintaining the highest standards of quality and safety.

ASTM International (American Society for Testing and Materials):

ASTM International, previously known as the American Society for Testing and Materials, stands out as a globally acknowledged organization for developing standards. Established in 1898, ASTM, a non-profit entity, is dedicated to formulating and publishing technical standards across an extensive array of materials, products, systems, and services. These standards serve as a universal benchmark, ensuring the quality, safety, and efficacy of various products and processes in industries worldwide.

ISO (International Organization for Standardization):

The International Organization for Standardization, or ISO, stands as an independent, non-governmental international body specializing in the formulation and publication of voluntary global standards. Founded in 1947, ISO operates as a vital force promoting innovation, interoperability, and quality assurance on a worldwide scale.

Both ASTM and ISO contribute significantly to the standardization landscape, endorsing best practices, elevating product quality, and championing safety and innovation across a myriad of industries globally. Organizations routinely reference ASTM and ISO standards to showcase compliance, ensure interoperability, and meet regulatory standards.
