Description

ASTM F3522-22

Active Standard: Standard Guide for Additive Manufacturing of Metals — Feedstock Materials — Assessment of Powder Spreadability

ASTM F3522

Scope

1.1 This guide provides definitions of the spreading behavior or spreadability of metal powder feedstock used in powder bed additive manufacturing (AM) – Powder Bed Fusion and Metal Binder Jetting. Definitions are made in terms of powder bed characteristic parameters, and suggests measurement methods that could be used to measure these parameters.

1.2 This standard is intended for the producers and users of powder feedstock used in powder bed AM to provide a common understanding of spreadability parameters. These parameters can be used as the basis for developing powder specifications that ensure proper powder spreadability.

1.3 This guide provides guidance to manufacturers and users of AM machines by providing possible techniques to quantify powder bed spreadability, and highlighting possible process parameters that may affect this spreadability. These parameters can be used as the basis for developing process specifications and for developing measures to improve the quality of spreadability in AM processes.

1.4 The values stated in SI units are to be regarded as the standard units. No other units of measurement are included in this standard.

1.5 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.

1.6 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.
