“…An IoT-enabled teleportation system was introduced. A platform that provides unique design via image, text, and G-code controls the nonface-to-face contact platform (www.makerspiece.com, CPMC, El Paso, TX, USA) [30]. The effect of the 3D-printed C/TPU is to provide a personalized design through a simple "clicks in the web" and plan to build a security design and device.…”

3D printable, flexible, and conductive composites are prepared by incorporating a thermoplastic elastomer and electrically conductive carbon fillers. The advantageous printability, workability, chemical resistance, electrical conductivity, and biocompatibility components allowed for an enabling of 3D-printed electronics, electromagnetic interference (EMI) shielding, static elimination, and biomedical sensors. Carbon-infused thermoplastic polyurethane (C/TPU) composites have been demonstrated to possess right-strained sensing abilities and are the candidate in fields such as smart textiles and biomedical sensing. Flexible and conductive composites were prepared by a mechanical blending of biocompatible TPU and carbons. 3D structures that exhibit mechanical flexibility and electric conductivity were successfully printed. Three different types of C/TPU composites, carbon nanotube (CNT), carbon black (CCB), and graphite (G) were prepared with differentiating sizes and composition of filaments. The conductivity of TPU/CNT and TPU/CCB composite filaments increased rapidly when the loading amount of carbon fillers exceeded the filtration threshold of 8%–10% weight. Biocompatible G did not form a conductive pathway in the TPU; resistance to indentation deformation of the TPU matrix was maintained by weight by 40%. Adding a carbon material to the TPU improved the mechanical properties of the composites, and carbon fillers could improve electrical conductivity without losing biocompatibility. For the practical use of the manufactured filaments, optimal printing parameters were determined, and an FDM printing condition was adjusted. Through this process, a variety of soft 3D-printed C/TPU structures exhibiting flexible and robust features were built and tested to investigate the performance of the possible application of 3D-printed electronics and medical scaffolds.

“…This versatility of PTE 3D tattoo printing was favorable for ease of operation. Single line design (SLD) depicts an image using a single line, ensuring constant ink flow through the nozzle with high-viscosity materials [24][25][26]. The wettability (contact angle at the liquid-solid interface) of the material is crucial as the ink diffuses through the skin.…”

Background: The emphasis on non-face-to-face or untact operation services is on the rise due to the ongoing widespread of COVID-19 epidemics, which have caused severe damage worldwide. Untact technology has been applied not only to everyday life but also to the beauty art industry that relies on customer service with contact.Objective: A safe non-permanent tattoo ink is necessary to overcome the stigma of permanent tattoos and tattoo removal procedures. The purpose of this study is to efficiently deliver non-permanent tattoo ink into the skin through sophisticated untact printing techniques and safe silver compound ink, further minimizing the side effects due to unsanitary conditions. Methods: Silver-gelatin compound ink serves as an excellent alternative for conventional permanent tattoos with additives. Pistontype extruder (PTE) system and internet of things (IoT) integrated precision-controlled non-permanent and untact system using silver nanoparticle ink.Results: Complex and sophisticated designs were three-dimensional (3D) printed using a non-permanent tattoo ink containing an optimum concentration of Ag + under 5 N compression force through a 100 µm radius nozzle and diffused up to 200 µm into the stratum corneum through skin contact. Intradermal diffusion simulation and disappearance of the ink within two weeks of the human skin replacement cycle were successfully demonstrated. Conclusion:The integration of IoT and 3D printers has enabled a hygienic untact tattoo printing technique that has been verified through repeated testing. This study could arouse positive possibilities and interests in the rapidly changing beauty art fields. It provides a new tattoo methodology and further research ideas for the 3D printing applications in tattoo production.

“…Kim [16] reported that an internet-of-things (IoT) printing method could be used as an innovative approach to prevent simultaneous exposure of consumers and nail artists in close proximity. The economics and commercialization of nail art 3D printing have been analyzed for a business model in which consumers choose designs, ideas, and products from the web [17]. User-oriented custom 3D nail art manufacturing and delivery organizations have successfully tested advanced 3D nails that are different from the existing ones.…”

Background: With the spread of coronavirus disease-19 , face-to-face contact in business and educational hubs has decreased. This is especially true for the beauty industry, where long-term contact with operators and customers is required. Therefore, the emergence of new alternative business models is essential. Objective:The purpose of this study is to apply nonfacing and real-time three-dimensional (3D) nail-printing systems to cosmetic industries, educational institutions, and educational systems. Three-dimensional non-face-to-face printing equipment have enabled nail art to be precisely and remotely controlled, which facilitates the replacement of nail technology that is based on body contact. Methods:From January to April 2020, the use of the internet-of-things (IoT)-controlled non-face-to-face and real-time 3D nailprinting systems was tested. Nail artists and customers were isolated, and more than 200 patterns were tested with non-face-toface contact between Korea and the United States. A built-in IoT operating system was tested in an online platform, and the advantages and problems of non-face-to-face contact were systematically analyzed. Results:The rapid development of IoT-controlled non-face-to-face and real-time 3D nail-printing systems was achieved to reduce entry barriers for nail art utilizing 3D-printing technology. The most crucial parts were determined to be reliably creating 3D shapes, reproducibility, economical operation, and timely maintenance. Conclusion:The nail art business model, in which the education and business sectors depend entirely on face-to-face contact, has been disrupted and deemed unpredictable due to the social distancing norms that have been adopted for countering the COVID-19 epidemic. Nevertheless, secure and remote accessibility to non-face-to-face and real-time 3D nail-printing systems for nail artists were successfully applied and tested to respond to this situation.
