W. CONSHOHOCKEN, Pa., May 26, 2015—ASTM International Committee F42 on Additive Manufacturing Technologies is working on a standard that will be used to evaluate mechanical properties for additively manufactured materials.
The standard (WK49229, Guide for Anisotropy Effects in Mechanical Properties of AM Parts) will serve as a guideline for using currently available standards for measuring mechanical properties, such as fracture toughness and fatigue crack growth, specifically within the realm of additive manufacturing.
Many mechanical testing standards are applicable to parts made by additive manufacturing, according to ASTM member Mohsen Seifi, a doctoral researcher at Case Western Reserve University. However, these standards do not provide enough guidance tailored to the emerging technology of additive manufacturing. The focus of the proposed standard will be guiding users to adopt or apply current available standards but with considerations and guidelines unique to additive manufacturing.
Vendors and manufacturers will use the standard to partially qualify parts and components to meet certain load bearing capability, damage tolerance, fracture and fatigue properties. Industries that use such parts will be able to use the standard for certification and qualification purposes as well. Regulatory bodies and testing labs will also benefit from the standard.
In addition to WK49229, Committee F42 is working on other standards that will be used to fully qualify additive manufacturing parts. All interested parties are welcome to join the committee’s work.
