A new ASTM International working standard may be on the books soon. The proposed standard,”Practice for Metal Powder Bed Fusion to Meet Rigid Quality Requirements” (WK46188) will outline the protocol for the operation and production of powder bed fusion machines used in additive manufacturing and 3-D printing.
The working instruction will contain requirements for parts made with powder bed fusion methods that use laser and electron beam sources. “Powder bed fusion” generally refers to manufacturing processes that use a laser to fuse or melt metal powders in a bed. Electron beam melting, selective laser sintering, selective laser melting and direct metal laser sintering can all be used to create products using “powder bed fusion.”
This directive will likely be used by suppliers setting up shop to create parts using powder bed fusion processes and manufacturers who will use the guidelines to create their own in-house guidelines.
The guideline will increase the safety and quality of parts created via powder bed fusion according to Shane Collins, ASTM member and director, program management, Incodema3d LLC. “Additive manufacturing is based on the capabilities of the machines used in the process,” said Collins. “The machines have been historically designed for the rapid prototyping industry, and we are taking those same machines and now asking them to make safety critical components. WK46188 will illustrate what the critical parameters for successful powder bed fusion are, how to determine the upper and lower limits of the process and ensure all components are exactly the same.”
ASTM F3091 or “Specification for Powder Bed Fusion of Plastic Materials” is a written standard for powder bed fusion of plastic materials. It specifies end-use properties such as mechanical, tolerance, surface finishing and post-processing for polyamide parts produced using SLS. ASTM F3049 or “Guide for Characterizing Properties of Metal Powders Used for Additive Manufacturing Processes,” will benefit those who use and make metal powders in the automotive, aerospace and medical fields.
It is without a doubt that a solid set of standards will need to be in place as the technology around additive manufacturing continues to rapidly develop. ASTM has also recently signed a MOU with America Makes outlining a framework for cooperation between the two, in hopes of creating a set of standards within the industry. Let’s hear your thoughts on this story in the additive manufacturing standards forum thread on 3DPB.com.
