ASTM F3318-18 PDF

Full title and description

Standard for Additive Manufacturing – Finished Part Properties – Specification for AlSi10Mg with Powder Bed Fusion – Laser Beam (ASTM F3318-18). This specification defines minimum ordering, material, processing, post-build chemical and mechanical property, inspection, marking, packaging, and quality requirements for parts made from AlSi10Mg using laser powder bed fusion processes.

Abstract

This specification applies to additively manufactured AlSi10Mg parts produced by powder bed fusion (laser melting). It establishes requirements for feedstock chemical composition, processing and post-processing, microstructure and minimum mechanical properties (including minimum tensile properties), thermal processing, retests, inspection and certification, product marking and packaging, and the supplier quality program. Supplementary requirements (S1–S16) allow purchasers to specify more stringent or additional requirements where needed.

General information

• Status: Active standard.
• Publication date: 1 May 2018 (designation F3318-18).
• Publisher: ASTM International (Committee F42, Subcommittee F42.05).
• ICS / categories: 25.030 (Additive manufacturing); 77.120.10 (Aluminium and aluminium alloys).
• Edition / version: F3318-18 (2018 edition).
• Number of pages: 8 pages; DOI 10.1520/F3318-18.

Scope

The scope covers AlSi10Mg parts manufactured using powder bed fusion laser-beam methods and intended for applications where mechanical properties are similar to or exceed those of cast equivalents. It is intended for use by purchasers and producers to define and enforce minimum finished part properties, and notes that additional purchaser-specified supplementary requirements may be applied. The values in SI units are normative; the standard does not address all safety concerns and users must establish applicable safety practices.

Key topics and requirements

• Definition and ordering information for additively manufactured AlSi10Mg parts.
• Feedstock chemical composition limits for AlSi10Mg (pre-alloyed powder).
• Processing requirements for laser powder bed fusion and relevant build parameters.
• Post-build requirements including recommended post-processing (machining, EDM, polishing) and heat treatments.
• Minimum mechanical property requirements (tensile properties) and microstructural expectations.
• Inspection, testing, retest rules, certification and acceptance criteria.
• Product marking, packaging, and supplier quality program expectations.
• Supplementary requirements (S1–S16) to address more stringent purchaser needs.

Typical use and users

Used by additive manufacturing service providers, OEMs, purchasers, design and materials engineers, and quality managers in industries such as aerospace, automotive, defense, tooling, and research organizations seeking consistent, reproducible properties from AlSi10Mg parts produced by laser powder bed fusion. It is used both for procurement specifications and for supplier quality agreements.

Related standards

Related ASTM and ISO/ASTM AM standards commonly referenced alongside F3318-18 include standards for AM terminology, test artifacts, reporting, and post-processing — for example ISO/ASTM 52900 series (AM terms and principles), ASTM F3301 (thermal post-processing of metal powder bed fusion parts), ASTM F2971 (reporting data for AM test specimens), and ASTM F3122 (evaluation of mechanical properties for metallic AM materials). These documents are often used together to define process, material, and test requirements for metal AM parts.

A: ASTM F3318-18 is a specification that defines finished-part property requirements for AlSi10Mg parts made by laser powder bed fusion (metal additive manufacturing).

Q: What does it cover?

A: It covers ordering information, chemical composition of feedstock and post-build composition, required minimum mechanical properties (including tensile), microstructure, thermal processing, inspection and certification, marking, packaging, and supplier quality program requirements, plus optional supplementary requirements purchasers can invoke.

Q: Who typically uses it?

A: AM service providers, manufacturers using AlSi10Mg parts, engineering and quality teams in aerospace, automotive, defense, tooling, and research organizations, and purchasers who need to specify minimum material and finished-part properties.

Q: Is it current or superseded?
