1.1 Purpose
This standard specifes requirements for qualifcation of the manufacturing process, production, marking,and documentation of additively manufactured metallic components used in the petroleum and natural gas industries when referenced by an applicable API equipment standard or otherwise specifed as a requirement for conformance. The qualifcation process fowchart is shown in Figure 1.
1.2 Applicability
This standard applies to additively manufactured metallic components produced by powder bed fusion (PBF),directed energy deposition (DED), and binder jetting (BJT) processes.
1.3 Additive Manufacturing Specifcation Levels (AMSL)
This standard establishes requirements for three additive manufacturing specifcation levels (AMSL). These three AMSL designations—AMSL 1, AMSL 2, and AMSL 3—defne increasing levels of additive manufacturing technical, quality, and qualifcation requirements.
NOTE An AMSL can be assigned to a component by a product specifcation or standard, the purchaser, or the manufacturer.
