Additive Manufacturing technologies have the potential to be of significance in the field of secure documents. The aim of this paper is to show with examples areas where these could arise. It concentrates on the areas where Additive Manufacturing can add tactile features to a document as this could well be the area where the technology has earliest significance in security printing. To a certain extent 2.5D printing already exists in the security sector, but not specifically from the digital domain. It may well be that Additive Manufacturing will initially be a threat to these established features, rather than a source of new ones. So the paper illustrates the potential for Additive Manufacturing systems to duplicate existing tactile security features and then shows where this knowledge could be the source of new features. The work also considers the possibility for the fabrication of optical features for secure documents by Additive Manufacturing.
