Additive manufacturing counterfeiting obfuscation

A method of forming additive manufactured parts with obfuscated anti-counterfeiting features, the method comprising:

• additive manufacturing a plurality of parts using an approved additive manufacturing method, wherein the additive manufacturing comprises forming a plurality of obfuscated anti-counterfeiting structures on a surface of each of the plurality of parts, wherein:
• each of the plurality of obfuscated anti-counterfeiting structures comprises at least one of a prohibitive physical dimension and a prohibitive physical shape,
• the prohibitive physical dimension being a length, width, depth, or angle of orientation of an additive manufactured structure that is properly produced without defects with an approved additive manufacturing method method and is improperly made with an unapproved additive manufacturing method,
• the prohibitive physical shape being a shape that is properly made without defects with an approved AM method but is improperly made with an unapproved AM method;
• and
• the plurality of obfuscated anti-counterfeiting structures is prohibitive from being formed without defects using at least one unapproved additive manufacturing method.

A method of forming additive manufactured parts with obfuscated anti-counterfeiting features, the method comprising:

• additive manufacturing a plurality of parts using at least one approved additive manufacturing method such that each of the plurality of parts comprises a surface with a plurality of obfuscated anti-counterfeiting structures, wherein:
• the plurality of obfuscated anti-counterfeiting structures comprises at least two of a plurality of hollow structures, a plurality of solid structures, and a plurality of truss structures,
• each of the plurality of obfuscated anti-counterfeiting structures comprises at least one of a prohibitive physical dimension and a prohibitive physical shape, and
• the plurality of obfuscated anti-counterfeiting structures is prohibitive from being formed using at least one unapproved additive manufacturing method such that counterfeit manufacture of the plurality of parts using at least two unapproved additive manufacturing methods is detected by inspecting the surface or observing a build failure by the at least one unapproved additive manufacturing method.
