Abstract: Digital and analog contents, generated in additive manufacturing (AM) processes, may be illegally modified, distributed, and reproduced. Within this article, we propose a watermarking scheme to boost the safety of AM. Compared with standard watermarking techniques, our algorithm possesses the following advantages. First, it protects geometric models and printed parts also as G-code applications. Secondly, it embeds watermarks into both polygonal and volumetric models. Thirdly, our strategy is capable of developing watermarks inside the interiors and around the surfaces of complicated models. Fourth, the watermarks may perhaps appear in a variety of types, like character strings, cavities, embossed bumps, and engraved textures. The proposed watermarking method is composed of your following measures. Initially, the input geometric model is converted into a distance field. Then, the watermark is inserted into a region of interest by utilizing self-organizing mapping. Ultimately, the watermarked model is converted into a G-code system by utilizing a specialized slicer. A number of robust strategies are also developed to authenticate digital models, G-code plan.
