This paper examines the intellectual property (IP) challenges introduced by 3D printing, a transformative technology enabling widespread innovation, but also raising critical legal questions. It focuses on three main areas: (1) IP issues associated with printing hardware, (2) copyright and licensing complexities related to downloadable files, (3) concerns for commercialized printed items. Through comprehensive review, highlights how existing frameworks struggle keep pace flexibility accessibility inherent in printing. Proposed solutions, such as blockchain secure design tracking enhanced digital rights management (DRM), point towards more controlled future protection. Additionally, study underscores need international cooperation harmonize laws, facilitating effective cross-border enforcement. work aims contribute ongoing dialogue proposing adaptive strategies support clarity while fostering technological advancement.

Abstract Information security and temperature sensing play vital roles in various areas such as financial transactions, product authentication, privacy protection. However, integrating precise control information technologies with highly sensitive remains a significant challenge. Here, multilayer core–shell upconversion nanoparticle (UCNP) system is presented that enables dynamic dual‐color emission switching through controlled energy transfer mechanisms. By tuning the excitation wavelength, power density, pulse width, exhibits green‐to‐blue transition multimodal tunability. Using fluorescence intensity ratio techniques, maximum relative sensitivity of 1.85% K −1 , demonstrating superior detection performance achieved. Furthermore, tunable multicolor properties UCNPs enable diverse applications security, including pattern recognition, Morse code encryption, quick response code‐based anti‐counterfeiting. This research not only broadens application scope environmental monitoring but also offers perspectives on design multifunctional optical materials.
