Additive manufacturing of polymers - Qualification principles - Part 1: General principles and preparation of test specimens for PBF-LB (ISO/ASTM 52936-1:2023)
This document specifies the general principles to be followed when test specimens of thermoplastic materials are prepared by laser-based powder bed fusion (PBF-LB/P), which is commonly known as laser sintering. The (PBF-LB/P) process is used to prepare test specimens layer upon layer in which thermal energy selectively fuses regions of a powder bed. This document provides a basis for establishing reproducible and reportable 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.
This document does not specify the test procedure itself.
Additive Fertigung von Polymeren - Qualifizierungsgrundsätze - Teil 1: Allgemeine Grundsätze und Herstellung von Probekörpern für laserbasierte Pulverbettfusion (PBF-LB) (ISO/ASTM 52936-1:2023)
Dieses Dokument legt die allgemeinen Grundsätze fest, die befolgt werden müssen, wenn Probekörper thermoplastischer Werkstoffe durch laserbasierte Pulverbettfusion (PBF LB/P), allgemein bekannt als Laser-Sintern, vorbereitet werden. Das (PBF LB/P)-Verfahren wird zur schichtweisen Herstellung von Probekörpern Schicht auf Schicht verwendet, wobei Regionen eines Pulverbetts durch thermische Energie selektiv verschmolzen werden. Dieses Dokument liefert die Grundlage für die Etablierung reproduzierbarer und berichtbarer Sinterbedingungen. Sein Zweck besteht darin, die Einheitlichkeit der Beschreibung der Hauptprozessparameter, Bauteilausrichtung des Sinterverfahrens zu unterstützen und auch eine einheitliche Praxis bei der Berichterstattung zu Sinterbedingungen zu etablieren.
Dieses Dokument legt nicht das Prüfverfahren selbst fest.

Fabrication additive de polymères - Principes de qualification - Partie 1: Principes généraux et préparation des éprouvettes pour PBF-LB (ISO/ASTM 52936-1:2023)
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.

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

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.
