Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see
www.iso.org/iso/foreword.html.
This document was prepared by ISO/TC 261, Additive manufacturing, in cooperation with ASTM
Committee F42, Additive Manufacturing Technologies, on the basis of a partnership agreement between
ISO and ASTM International with the aim to create a common set of ISO/ASTM standards on additive
manufacturing, and in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 438, Additive manufacturing, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This second edition of ISO/ASTM 52900 replaces the first edition (ISO/ASTM 52900:2015), which has
been technically revised. The main changes compared to the previous edition are as follows:
— new and modified terms and definitions;
— abbreviations added for seven process categories;
— new annex for the specification of AM processes based on process categories and determining
characteristics (Annex A).
Any feedback or questions on this document should be directed to the user’s national standards body. A

ISO/ASTM 52900:2021(E)
Introduction
Additive manufacturing (AM) is the general term for those technologies that successively join material
to create physical objects as specified by 3D model data. These technologies are presently used for
various applications in engineering industry as well as other areas of society, such as medicine,
education, architecture, cartography, toys and entertainment.
During the development of additive manufacturing technology, there have been numerous different
terms and definitions in use, often with reference to specific application areas and trademarks. This
is often ambiguous and confusing, which hampers communication and wider application of this
technology.
It is the intention of
