ASTM

ASTM International, formerly known as the American Society for Testing and Materials, is an international standards organisation that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.

ASTM defined the seven categories of AM which which are now recognised at the definitive classification of all the technology types.

ASTM acquired Wohlers Associates who produce the annual Wohlers Report providing the industry standard analysis of the state of the 3D printing and Additive Manufacturing market.

Originally formed in 1898 to develop a standard for steel to be used in train rails in response to frequent rail breaks across the expanding railroad system.
