Inventory of current domestic and international standards for additive manufacturing

In recent years, many additive manufacturing standards have been released one after another, covering a wide range from design guidelines to materials, processes, equipment, testing and qualification certification of employees. In fact, many standards are still in the exploratory stage at present. With the deepening of people’s understanding of this technology, the relevant standards are constantly improving.

In this issue, we list the additive manufacturing standards issued by ASTM International and ISO, two authoritative organizations in the field of standardization, and introduce the standards being developed and issued by SAE and China.

ASTM: Committed to improve the additive manufacturing standard system

ASTM established ASTM F42 in 2009 as the first standardization association organization of the Additive Manufacturing Technical Committee. Its main goal is to develop the characteristics and performance standards, test methods and procedure standards in the fields of additive manufacturing materials, products, systems and services, so as to promote the popularization of additive manufacturing technology and industrial development.
In 2012, ASTM F42 published the F2792-12A terminology standard for additive manufacturing, and in 2015, in cooperation with ISO, the standard was revised, and the first ISO/ASTM joint standard was published to regulate the terms and definitions in the promotion of additive manufacturing technology and industry development. So far, its standard specifications are as follows:

ISO: To improve the scientific, rational and efficient quality of additive manufacturing standards

The international organization for standardization (ISO) in 2011 to create ISO/TC 261 material manufacture standardization technology committee, its scope of work is: in the increase of material manufacturing (AM) standardization within the territory involved process, terms and definitions, process chain (hardware and software), test procedure, quality parameters, supply agreement, and all the basis of generic technology. ISO/TC 261 signed a cooperation agreement with ASTM F42 when it was founded to standardize the field of additive manufacturing technology. In 2013, ISO/TC 261 and ASTM F42 jointly published a “Joint Plan for the Development of Additive Manufacturing Standards”, which includes a common structure/hierarchy of AM standards so that projects initiated by either party can achieve consistency. Standard F42 for Additive Manufacturing is regularly reviewed and updated. In 2016, the structure was revised.

Environment, health and safety

At present, there are more than 40 standards in ISO TC261 and ASTM F42, and the standardization work is carried out from the aspects of additive manufacturing materials and processes, test methods, design, safety protection, etc., to further improve the standard system of additive manufacturing, which plays an important role and significance in the standardization work of additive manufacturing.

Establish additive manufacturing standards for the Federal Aviation Administration

In July 2015, SAE established the AMS-AM Technical Committee, which is responsible for the development and maintenance of aerospace materials and process specifications and standards related to additive manufacturing, as well as related technical reports. In October 2015, the Federal Aviation Administration (FAA) commissioned SAE to develop additive manufacturing technology standards for specific certification requirements for critical aerospace applications, and to develop AM material certification guidelines for the FAA. The main objectives of AMS-AM include:

  • Aerospace Materials Specification (AMS) for procurement of raw materials and finished materials;
  • Recommends practices, codes and standards for aerospace manufacturing processes;
  • Coordinate with MMPDS, CMH-17, NADCAP, ASTM F42 to promote the adoption of standards in the industry;
  • Establish a system of standards (technical documentation) to ensure that processes are controlled and traceable to obtain statistically significant material performance data.

To date, SAE has issued and is developing a total of 30 standards, covering laser and electron beam powder bed melting, plasma arc fusion, laser fusion, laser direct deposition, material melt extrusion process, In625, In718, 17-4PH, Hastelloy X, Haynes 230, Ti6242, Ti6Al4V, AlSI10MG, ULTEM 9085, ULTEM1010 and other materials.
