Additive manufacturing - General principles - Overview of data processing (ISO/ASTM 52950:2021)
This document covers the principal considerations which apply to data exchange for additive
manufacturing. It specifies terms and definitions which enable information to be exchanged describing
geometries or parts such that they can be additively manufactured. The data exchange method outlines
file type, data enclosed formatting of such data and what this can be used for.
This document
— enables a suitable format for data exchange to be specified,
— describes the existing developments for additive manufacturing of 3D geometries,
— outlines existing file formats used as part of the existing developments, and
— enables understanding of necessary features for data exchange, for adopters of this document.
This document is aimed at users and producers of additive manufacturing processes and associated
software systems. It applies wherever additive processes are used, and to the following fields in
particular:
— producers of additive manufacturing systems and equipment including software;
— software engineers involved in CAD/CAE systems;
— reverse engineering systems developers;
— test bodies wishing to compare requested and actual geometries.

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.

This document was prepared by Technical Committee 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 first edition of ISO/ASTM 52950 replaces ISO 17296-4:2014, which has been technically revised
and renumbered. The main changes compared to ISO 17296-4:2014 are as follows:
— change of the document number to ISO/ASTM 52950;
— removal of outdated or withdrawn standards ISO 17296-4 and DIN 66301 (VDA-FS);
— revisions to Figure 1.

Additive manufacturing is used to fabricate prototypes, tools, and production parts.
This document aims to offer recommendations and advice to users (customers) and manufactures (both
external and internal service providers), to improve communication between customer and supplier,
and to contribute to an authoritative performance design and a smooth handling of the project.
It assumes that the reader has a basic understanding of the process flow of different additive processes.
It explains the processes used in practice in only as much detail as it necessary to understand the
statements.

Introduction
Additive manufacturing are an inherent part of the product development process. They are used to
manufacture prototypes, tools, and production parts.
In addition to engineering, the scope of this interdisciplinary technology now covers fields ranging
from architecture and medicine to archaeology and cartography.
During its somewhat turbulent development, different terms and definitions have emerged which are
frequently ambiguous and confusing. Moreover, there are different processes available on the market
and it is not always clear what opportunities and limitations they offer in terms of application.
This document aims to offer field-tested recommendations and advice to users (customers) and
manufactures (both external and internal service providers), to improve communication between
customer and supplier, and to contribute to an authoritative performance design and a smooth handling
of the project.
It assumes that the reader has a basic understanding of the process flow of different additive processes.
It explains the processes used in practice in only much detail as it necessary to understand the

4.1 Dataflow
4.1.1 General
A complete 3D data set of the part forms the basis of additive manufacturing. Most commonly, this is
created by direct 3D CAD modelling. The data sets can also be generated by 3D Scanned data if the
parts exist in a physical form (see Figure 1).
A representation based on facets is then generated from the volume or area model
