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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are

Introduction
For many companies, additive manufacturing represents an alternative to more conventional
manufacturing processes such as casting, forging or milling. The trend towards complex components,
decentralised production and customer specific products allows an economically feasible use for more
and more areas. This also applies to many series applications, which comprise completely different
demands on the efficiency of the processes. In particular, components used in different fields (e.g.,
automotive industry, mechanical engineering, railway sector, aerospace, process and industrial plants,
medical technology, etc.) are subject to high demands in terms of quality and safety. This creates a need
for norms and standards that provide a transparent baseline for the production of components for a
great variety of application areas.
The manufacturing of products intended for applications subjected to specific requirements relies
on that the products' compliance to these requirements can be assured. Additive manufacturing is
no exception to this. To this end, the production chain and environment should be designed in such a
way that the process quality and the resulting product quality are always consistent and reproducible.
To assure this consistency and reproducibility, it is of utmost importance to assure that the involved
workforce is adequately qualified for all stages in the production.
