Additive manufacturing of polymers - Qualification principles - Part 1: General principles and preparation of test specimens for PBF-LB (ISO/ASTM FDIS 52936-1:2022)

This document specifies the general principles to be followed when test specimens of thermoplastic materials are prepared by laser-based powder bed fusion, which is also called laser sintering. The laser-sintering process is used to prepare specimens layer upon layer in which thermal energy selectively fuses regions of a powder bed. This document provides a basis for establishing reproducible sintering conditions. Its purpose is to promote uniformity in describing the main process parameters, build orientation of the sintering process and also to establish uniform practice in reporting sintering conditions.
The particular conditions required for reproducible preparation of test specimens which will give comparable results will vary for each material used. These conditions shall be agreed upon between the interested parties.

Additive Fertigung - Qualifizierungsgrundsätze - Laserbasiertes pulverbettbasiertes Schmelzen von Polymeren - Teil 1: Allgemeines und Herstellung von Prüfkörpern (ISO/ASTM FDIS 52936-1:2022)

Dieses Dokument legt die allgemeinen Grundsätze fest, die bei der Herstellung von Probekörpern aus thermoplastischen Werkstoffen durch laserbasierte Pulverbettfusion (PBF-LB/P), das allgemein als Laser-Sintern bekannt ist, zu beachten sind. Das (PBF-LB/P)-Verfahren dient der schichtweisen Herstellung von Probekörpern, bei der durch thermische Energie bestimmte Bereiche eines Pulverbettes verschmolzen werden. Dieses Dokument bietet eine Grundlage zur Festlegung von reproduzierbaren und berichtspflichtigen Sinterbedingungen. Der Zweck ist die Förderung der Einheitlichkeit bei der Beschreibung der wichtigsten Prozessparameter, der Auslegung des Sinterverfahrens und auch die Festlegung einer einheitlichen Praxis bei der Berichterstattung über die Sinterbedingungen.
Dieses Dokument enthält keine Angaben über das Prüfverfahren an sich.

Fabrication additive de polymères - Principes de qualification - Partie 1: Principes généraux et préparation des éprouvettes pour PBF-LB (ISO/ASTM FDIS 52936-1:2022)

Le présent document spécifie les principes généraux à suivre lorsque des éprouvettes en matériaux thermoplastiques sont préparées par fusion laser sur lit de poudre (PBF-LB/P), qui est communément connue comme frittage laser. Le procédé (PBF-LB/P) est utilisé pour préparer des éprouvettes couche après couche, dans lesquelles l’énergie thermique fait fondre de manière sélective des zones d’un lit de poudre. Le présent document fournit une base pour établir des conditions de frittage reproductibles et consignables dans un rapport. Son but est de favoriser l’uniformité des descriptions des principaux paramètres du procédé, l’orientation de fabrication du procédé de frittage, et également d’établir une pratique uniforme de consignation des conditions de frittage dans un rapport.
Le présent document ne spécifie pas le mode opératoire d’essai proprement dit.

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 www .iso .org/

iso/ foreword .html.

The committee responsible for this document is 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.

This first edition of ISO/ASTM 52936-1 cancels and replaces ISO 27547-1, which has been technically

revised.
The main changes compared to ISO 27547-1 are as follows:

— New standard number and title to make clear its status as additive manufacturing standard;

— Requirements for conditions revised to allow use of state of the art machines;

— Informative Annex B deleted because this procedure is not state of the art anymore.

Introduction

Many factors in an additive manufacturing test specimen-preparation process can influence the

properties of the test specimens prepared and hence the measured values obtained when the test

specimens are used in a test method. The mechanical properties of such test specimens are in fact

strongly dependent on the conditions of the process used to prepare the test specimens. Exact definition

of each of the main parameters of the process is a basic requirement for reproducible operating

conditions.

It is important in defining test specimen-preparation conditions to consider any influence the conditions

could have on the properties to be determined. Test specimens prepared by additive manufacturing

techniques can show differences in molecular morphology (as with crystalline and semicrystalline

polymers), differences in powder morphology (after undergoing a sintering process, for instance),

differences in thermal history and differences in thickness of the layers, test specimen orientation or

test specimen location, used to prepare the specimen. Only if each of these is controlled can differences

in the values of the properties measured be avoided.

This international Standard has been developed by ISO/TC 261, ISO/TC 61/SC 9 and ASTM F42 in close

cooperation on the basis of a partnership between ISO and ASTM international with the aim to create a

common set of ISO/ASTM standards on Additive Manufacturing.
