| Abstract Scope |
Information embedding techniques address security, counterfeiting, and intellectual property concerns by storing secure information inside of parts, but they require reliable information retrieval methods. This research proposes and discusses the feasibility of information embedding schemes that implement nondestructive evaluation methods to decode the information via two case studies. In both cases, binary geometries are encoded by varying printing parameters in fused filament fabrication (FFF) polylactic acid (PLA) samples. One case study emphasizes geometric precision, while the other focuses on sensitivity to print parameter variations. The information is retrieved with both X-ray computed tomography (CT) and ultrasonic imaging, highlighting the capabilities of each modality, their tradeoffs, and their combined use potential. The results demonstrate the viability of these information embedding and retrieval methods and lay the groundwork for their further development. |
