Overview

EN ISO 17295:2023 - Additive manufacturing: Part positioning, coordinates and orientation (ISO 17295:2023) defines a standardized method to describe how parts are located and oriented in additive manufacturing (AM) build volumes. It specifies coordinate systems, bounding boxes, initial build orientation and notation for orthogonal orientations to ensure consistent reporting and reproducibility across AM users, producers, researchers, educators and the media. The standard is aligned with the principles of ISO 841 and references terminology in ISO/ASTM 52900.

Key topics and technical requirements

• Machine coordinate systems - Illustrates 3‑D Cartesian coordinate systems for common AM machines, including differences for upward and downward Z‑positive build directions.
• Axes of rotation - Defines the rule for positive rotation axes (A, B, C) consistent with right‑hand screw convention.
• Bounding box - Describes part bounding boxes and distinctions between machine‑aligned, part‑aligned, and arbitrarily oriented bounding boxes for clear geometric description.
• Initial build orientation - Specifies how the orientation of a part when first placed in the build volume should be represented.
• Orthogonal orientation notation - Provides a notation system and abbreviations for describing orthogonal orientations and bilateral symmetry.
• Representation of part location and reorientation - Gives methods to document part placement and any subsequent reorientation during testing or processing.
• Normative references - Requires use of ISO 841 for coordinate/motion nomenclature and ISO/ASTM 52900 for AM vocabulary.

Practical applications

This standard is intended to improve clarity, repeatability and comparability of AM results by standardizing how part position and orientation are reported. Typical uses include:

• Test and qualification reports for mechanical, thermal or dimensional testing of AM parts.
• Build preparation and documentation by AM machine manufacturers and service bureaus.
• Research papers and inter‑laboratory studies where orientation affects material properties, surface finish or support needs.
• Educational materials and media coverage to reduce ambiguity when describing how parts were printed.
• Quality control, traceability and process documentation in regulated industries using AM.

Who should use it

• AM equipment manufacturers and software developers (build preparation tools)
• Materials and process researchers
• Test laboratories and certification bodies
• AM service providers and production shops
• Educators, technical writers and journalists reporting AM test results

Related standards

• ISO 841 - Coordinate system and motion nomenclature (basis for axis rules)
• ISO/ASTM 52900 - Additive manufacturing vocabulary and fundamentals
• EN ISO 17295:2023 is the CEN‑adopted European version of ISO 17295:2023

Keywords: additive manufacturing, part positioning, coordinates, orientation, ISO 17295, build orientation, bounding box, machine coordinate system, AM testing.

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

This document was prepared by Technical ISO/TC 261, Additive manufacturing, 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).
The first edition of ISO 17295 cancels and replaces ISO/ASTM 52921:2013, which has been technically
revised.
The main changes are as follows:
— terms and definitions that are included in ISO/ASTM 52900 have been removed from this document
and instead referred to ISO/ASTM 52900;
— since the list of terms and definitions have been removed from this edition, it is therefore not a
standard terminology anymore, and therefore it has been renamed so that the title describes the
actual content of the standard;
— the remaining normative content of the document including the annex have been consolidated into
one single normative document;
— specifications of some aspects of initial build orientation and orthogonal orientation notation have
been integrated in the text body of the document.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.
