“…In another study, Suzuki et al [ 31 ] proposed a technique of steganography inside AM parts by forming high-reflectance projections. Except for watermarking techniques mentioned above, this was the first time that steganography was carried out on actual 3D-fabricated parts.…”

“…Usage of PCA resulted in the failure in decoding if the right alignment of models is not obtained. The work of Suzuki et al [ 31 ] was the first steganographic approach of AM parts depending on the density difference of the embedded projections. A higher capacity and robustness was found from the results of the experiment.…”

The paper gives a detailed review of the approaches adopted for embedding information into/onto additively manufactured parts. The primary purpose of this paper is to review all the techniques adopted for embedding information, highlight notable trends and improvements in these works, and provide design and manufacturing pipelines to realize most of these works. It classifies these approaches into four different categories and summarizes the works carried out in each field. It also compares all the results in textual and tabular forms and then gives a detailed conclusion of the best works in terms of application and effectiveness. The four categories discussed are 3D QR codes, 3D watermarking, steganography and nonclassified methods. Lastly, it discusses the future extensions and potential improvements in the field of embedding information, while exploring manufacturing technologies.

“…However, their method is also limited to PolyJet 3D printers and is susceptible to layer variations such as uniformed thickness, as the authors use a THz-TDS (TeraHertz Time-Domain) device for imaging. While there are prior examples of using FDM 3D printers to embed information, their design severely limits functionality in application and durability [60,65]. Their methods are incapable of producing embedded information beyond binary due to their restrictive design between adjacent bits.…”

We present a technique to embed information invisible to the eye inside 3D printed objects. The information is integrated in the object model, and then fabricated using off-the-shelf dual-head FDM (Fused Deposition Modeling) 3D printers. Our process does not require human intervention during or after printing with the integrated model. The information can be arbitrary symbols, such as icons, text, binary, or handwriting. To retrieve the information, we evaluate two different infrared-based imaging devices that are readily available -thermal cameras and near-infrared scanners. Based on our results, we propose design guidelines for a range of use cases to embed and extract hidden information. We demonstrate how our method can be used for different applications, such as interactive thermal displays, hidden board game tokens, tagging functional printed objects, and autographing non-fungible fabrication work.

“…This information could not be captured with a visible light camera. Several subsequent studies successfully embedded and read information in the object interior using alternative methods: i.e., internal information read in the far infrared region [31], information embedded using highly reflective material [32], and information embedded in the form of air pockets and read using visible light projection [2]. Recently, Maia et al [4] embedded information in the entire surface of an object in order to simplify reading of the information.…”

Additive manufacturing has the potential to become a standard method for manufacturing products, and product information is indispensable for the item distribution system. While most products are given barcodes to the exterior surfaces, research on embedding barcodes inside products is underway. This is because additive manufacturing makes it possible to carry out manufacturing and information adding at the same time, and embedding information inside does not impair the exterior appearance of the product. However, products that have not been embedded information can not be identified, and embedded information can not be rewritten later. In this study, we have developed a product identification system that does not require embedding barcodes inside. This system uses a transmission image of the product which contains information of each product such as different inner support structures and manufacturing errors. We have shown through experiments that if datasets of transmission images are available, objects can be identified with an accuracy of over 90%. This result suggests that our approach can be useful for identifying objects without embedded information.
