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

This document was prepared by Technical Committee ISO/TC 261, Additive manufacturing, Joint Group

JG 74, Personnel Qualifications 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.

Qualification principles:
— Part 1: General qualification of operators
— Part 2: Qualification of operators for PBF-LB
— Part 3: Qualification of operators for PBF-EB
— Part 4: Qualification of e operators for DED-LB
— Part 5: Qualification of operators for DED-Arc

Introduction

For many companies, additive manufacturing represents an alternative to established manufacturing

processes. 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 industry (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. The current lack of norms and standards means that processes for the production

of components have to be defined from the scratch for each individual case, which causes a great effort

and allows little transparency and thus little trust of other stakeholders in the processes.

If industrially used components are manufactured using additive manufacturing processes, it shall be

proven that these meet the requirements. To this end, the production chain and environment shall be

designed in such a way that the process quality and th
