This document specifies test methods to determine particle emissions (including ultrafine particles) and specified volatile organic compounds (including aldehydes) from desktop MEX-TRB/P processes often used in non-industrial environments such as school, homes and office spaces in an emission test chamber under specified test conditions. However, these tests do not necessarily accurately predict real-world results. This document specifies a conditioning method using an emission test chamber with controlled temperature, humidity, air exchange rate, air velocity, and procedures for monitoring, storage, analysis, calculation, and reporting of emission rates. This document is intended to cover desktop MEX-TRB/P machine which is typically sized for placement on a desktop, used in non-industrial places like school, home and office space. The primary purpose of this document is to quantify particle and chemical emission rates from desktop MEX-TRB/P machine. However, not all possible emissions are covered by this method. Many feedstocks can release hazardous emissions that are not measured by the chemical detectors prescribed in this document. It is the responsibility of the user to understand the material being extruded and the potential chemical emissions. An example is Poly Vinyl Chloride feedstocks that can potentially emit chlorinated compounds, which cannot be measured by the method described in this document.

This document specifies the methodology for generic AM-machine evaluation in automotive environment
using objective test criteria and provides the framework for an objective AM-machine evaluation and
comparison. This document finds application in benchmarks, in the preparation of purchase decisions, but
also in AM-machine evaluation within the machine procurement, acceptance, and qualification processes.
This document is specific to automotive, as it is related to existing series part requirements of various
original equipment manufacturers, but the content can be transferred to other industries if necessary.
Furthermore, this document specifies machine KPIs in the context of machine procurement, production
planning and production of PBF-LB/M components. It aims to reach a detailed understanding between
machine supplier and machine user with respect to the acceptance criteria during the procurement process
and evaluation of machine performance during running production. For using this document, all process
parameters, such as scanning speed, laser power, etc., are fixed, since changing these parameters can affect
the entire process performance and its stability. Therefore, variables are not changed any more during
or after qualification. This document and the determination of the KPIs help in the evaluation of machine
properties, but do not replace an application-specific approval process.
This document is applicable to the additive manufacturing technology PBF-LB/M.

This document covers the general description of benchmarking test piece geometries, i.e. artefacts, along with quantitative and qualitative measurements to be taken on the benchmarking test piece(s) to assess the performance of additive manufacturing (AM) systems.
This performance assessment can serve the following two purposes:
—    AM system capability evaluation;
—    AM system calibration.
The benchmarking test piece(s) is (are) primarily used to quantitatively assess the geometric performance of an AM system. This document describes a suite of test geometries, each designed to investigate one or more specific performance metrics and several example configurations of these geometries into test build(s). It prescribes quantities and qualities of the test geometries to be measured but does not dictate specific measurement methods. Various user applications can require various grades of performance. This document discusses examples of feature configurations, as well as measurement uncertainty requirements, to demonstrate low- and high-grade examination and performance. This document does not discuss a specific procedure or machine settings for manufacturing a test piece.

Granular materials and fine powders are widely used in industrial applications. To control and optimize processing methods, these materials have to be precisely characterized. The characterization methods are related either to the properties of the grains (granulometry, morphology, chemical composition, ...) and to the behaviour of the bulk powder (flowability, density, blend stability, electrostatic properties, ...). The complex behaviours of granular and powder material has motivated the development of additional techniques to obtain reproducible and interpretable results. Many industries are concerned in different fields: additive manufacturing, food processing, pharmaceuticals, bulk material handling. The present technical report is focused on additive manufacturing. Metallic powders are widely used in Additive Manufacturing (AM) processes involving powder bed likepowder bed fusion (LBM, EBM, ...) or binder jetting. During such operations, successive thin layers of powderare created with a ruler or with a rotating cylinder. Each layer is then partially sintered or melted with an energy beam or glue with binder to build the parts. The layer thickness defines the vertical resolution of the printer; a thin layer leads to a better resolution. In order to obtain a thin layer, the powder is as fine as possible. However, as the grain size decreases, cohesiveness typically increases and spreadability, as defined within ASTM F42 / ISO/TC 261, is likely to decrease. The quality of the parts build with AM is thus directly influenced by powder flow properties.
Visual observation of layer homogeneity is usually the only way for operators to quantify the spreadability of powders  during  recoating. However, relating the powder characteristics to its spreadability during there coating process before hand should provide a more cost-effective way to classify and select the optimal powder and recoating speed combinations.
The aim of this technical report is to present an example of how the characterization of the macroscopic properties of metallic powders can be related to their spreadability inside LBM printers. A new technique combining measurements inside a LBM printer and image processing have been developed to quantify the homogeneity of the powder bed layers during recoating. Moreover, the flowability of four metal powders has been investigated with an automated rotating drum method, whose dynamic cohesive index measurement has been shown to correlate with the spreadability of the powder during the recoating  process.Furthemore, the PSD and morphology of each powder was characterized for each batch before testing bystatic image analysis method (ISO_13322-1_2014). The general principle of the study is presented on Figure 1

This guide will include post-process non-destructive testing of additive manufacturing (AM) of metallic parts with a comprehensive approach. It will cover several sectors and a similar framework can be applied to other materials (e.g. ceramics, polymers, etc.). In-process NDT and metrology standards will be referenced as they are being developed. This guide will present current standards capability to detect which of the Additive Manufacturing (AM) flaw types and which flaws require new standards, using a standard selection tool. NDT methods potential to detect AM flaws not covered by current standards will be recommended, and as new standards for flaws not covered by current standards are developed, they will be referenced in this standard via document updates.
This part of the International Standard:
⎯ Categorises AM defects
⎯ A review of relevant current standards
⎯ Enables suitable current standard NDT method/s to be used;
⎯ Details method specific to additive manufacturing and complex 3D geometries;
⎯ Outlines existing non-destructive testing techniques applicable to some AM types of defects;
This part of the International Standard is aimed at users and producers of additive
manufacturing processes. It applies wherever additive processes are used, and to the following fields in particular:
⎯ Safety critical applications;
⎯ Assured confidence in additive manufacturing;
⎯ Reverse engineered products manufactured by additively manufactured;
⎯ Test bodies wishing to compare requested and actual geometries.
NOTE Most metal inspection methods in NDT use ultrasound or X-rays, but these techniques cannot always cope with the complicated shapes typically produced by AM. In most circumstances X-ray computed tomography (CT) is a more suitable method, but it also has limitations and room for improvement or adaptation to AM, on top of being a costly method both in time and money.

This document establishes the required or the achievable classes of part properties for additive manufactured polymer parts in order to get a common understanding on part quality. It is aimed at providers of manufacturing services for polymer parts who use additive manufacturing machines and at the customers for these services. Designers of parts as well as buyers and providers of manufacturing services can specify, in a traceable manner, the required or the achievable level of part properties with the aid of this document. The classification is based on mechanical, physical and geometrical properties. Further properties can be defined between buyer and provider of manufacturing. This document is applicable to parts that have been manufactured from a thermoplastic polymer by means of thermal reaction fusion of material typically applied by a powder bed fusion (PBF) or material extrusion (MEX) processes. This document is also applicable to thermoplastic parts made by other processes, provided that due consideration is given to process-specific topics. The classification of part properties applies to parts in as-built condition, that have been unpacked from the build space, with all support structures removed, but prior to any post-processing operations. Specific industries (e.g. aerospace and medical) typically specify additional requirements.
