The additive manufacturing (AM) process chain relies heavily on cloud based resources and software programs that are connected to the internet. Cybersecurity has become a major concern for cloud based resources. While network security is important and is the responsibility of the information technology departments of corporations, a second line of defense is necessary if the cybersecurity is breached and the computer aided design (CAD) files are stolen. The stolen CAD files can be used to print components in exactly the same quality as the original component. The present work aims at developing design features in CAD models that can be used for the purpose of security against counterfeiting.
