scope:

These ABS Guidance Notes on Additive Manufacturing (AM) outline a procedure for systematically qualifying AM parts, processes, systems, and materials primarily intended for marine and offshore use. The scope of these Guidance Notes includes AM processes that are capable, either directly or indirectly, of producing metallic parts, including the following as outlined by ASTM F42: Directed Energy Deposition (DED), Powder Bed Fusion (PBF), and Binder Jetting (BJ). These Guidance Notes can be used to assess the capability of an AM process to produce an existing design, as well as new designs that may be specific to AM. These Guidance Notes follow a multi-staged approach to qualification similar to the ABS Guidance Notes on Qualifying New Technologies (NTQ). Each stage is designed to build upon the previous stage to develop a more complete understanding of the process.
