Standard Guide for Additive Manufacturing of Metals – Powder Bed Fusion – Guidelines for Feedstock Re-use and Sampling Strategies
SIGNIFICANCE AND USE
4.1 The overall aim of this guide is to support AM users with the selection of the optimum re-use strategy for their AM process and end-use application, and provide guidance on how to implement re-use strategies in their organization.
4.2 This guide suggests possible control measures that AM users can use to maintain powder quality, and factors to consider when validating selected re-use strategies, including guidance on sampling techniques.
4.3 This guide is intended for metal powders used in Powder Bed Fusion processes.
SCOPE
1.1 This guide:
1.1.1 Defines key powder re-use variables and factors affecting powder re-use strategies.
1.1.2 Outlines implications associated with implementation of powder re-use strategies based on selection of powder re-use variables and factors.
1.1.3 Provides guidance to AM users in selection of factors in powder re-use variables depending on considered material type, AM process type and end-use application.
1.1.4 Provides guidance on key process variables affecting powder properties, and considerations to mitigate their effects.
1.1.5 Identifies key powder properties that may be affected by powder re-use and provides AM users guidance on control measures that can be exploited to ensure quality of re-used powder.
1.1.6 Provides recommendations and guidance on factors to consider when implementing powder re-use strategies.
1.1.7 Provides information on how to design a powder re-use study to validate the selected re-use variables.
1.1.8 Summarizes sampling techniques and provides recommendations to AM users on sampling technique selection, and suitability of sampling techniques for powder re-use strategies.
1.1.9 Provides factors to consider when designing a powder sampling study to validate the selected sampling technique.
1.2 Units—The values stated in SI units are to be regarded as the standard units. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
