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.”
