scope:

This document is intended to serve as a best practice for the identification and "seeding" of nondestructively detectable flaw replicas of metal alloy PBF-LB and DED processes. Three seeding categories are described: 1. process flaws through CAD design, 2. build parameter manipulation, 3. subtractive manufacturing, and 4. depositing/inserting flaws after processing. These include flaws present within as-deposited materials, post heat-treated or HIP processed material, and those flaws made detectable because of post-processing operations. Geometrical aspects or measurement are not the subjects of this document.
