Additive Manufacturing—Nondestructive Testing—Intentionally Seeding Flaws in Metallic Parts

This document is intended to serve as a best practice for the identification and seeding of nondestructively detectable flaw replicas of metal alloy powder bed fusion (PBF) and directed energy deposition (DED) processes. Three seeding categories are described:
• process flaws through computer-aided design,
• build parameter manipulation, and
• subtractive manufacturing.

These include flaws present within as-deposited materials, post heat-treated or hot isostatic pressing (HIP) processed material, and those flaws made detectable because of postprocessing operations. Geometrical aspects or measurement are not the subjects of this document.
