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 International Standard 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 statements.

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).

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 International Standard 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 statements.

Additive manufacturing — General principles —
Part 4:
Overview of data processing
1 Scope

This part of ISO 17296 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 part of ISO 17296
— 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 the International

Standard.

This part of ISO 17296 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:
— production 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.

4 Data exchange
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 measurements 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 through polygonization

or triangulation (see 4.1.2.4) and transferred to the additive manufacturing process in STL or VRML

format (see 4.2.2 and 4.2.3). This software-assisted process runs automatically as far as possible.

4.1.2 Explanation of the key terms used in Figure 1
4.1.2.1 3D CAD modelling (solid modelling)

3D CAD modelling is the process most commonly used during design to produce a digital 3D model. The

starting point can be an idea for a product, which takes shape and becomes increasingly defined directly

on the computer screen during the process, or a previously generated image of the object in the form of

sketches, drawings, etc., which are then simply converted to 3D data. Volume can be described using two

different techniques, or a combination of both. The object is either composed of basic volumes (shapes)

(e.g. cuboid, wedge, cylinder, cone, sphere, and toroid) which generate the actual object via a sequence of

Boolean operations, or the volume is described by its surrounding boundary surfaces and the location

of the material relative to the boundary surfaces.
4.1.2.2 3D digitalization (reverse engineering)

3D digitalization is the process in which the surface geometry of a physical object is measured using

appropriate hardware and software and recorded in a digital point cloud model. The objects can be

manually produced or finished models which need to be copied in digital form. The use of 3D digitalization

is particularly efficient if the model has empirically drafted, freeform surface areas, since these are

difficult to reproduce through direct 3D CAD modelling.
