“…The demand for 3D-printed scaffolds that are biocompatible, structurally, and mechanically stable in the biomedical research field is increasing over time, and this work contributes to meet this mechanical demand. Although attempts and studies have been made to accurately print hard ceramics, such as artificial teeth or soft materials, such as biomaterials or food, actual in vivo or in vitro tests are expected to require much research [ 24 , 25 ]. For the application of biomaterials, different types of materials can be used for FDM, including metals, plastics, and, more recently, biocompatible materials.…”

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.

Purpose The purpose of this paper is to report the analysis of factors influencing additive manufacturing (AM) application in the food domain. Design/methodology/approach Based on literature review, 16 factors are being considered in the study. Interpretive structural modelling is used as a modelling approach. The derived structural model indicates the dominant factors. Matriced’ impacts croises-multipication applique and classment (cross-impact matrix multiplication applied to classification) (MICMAC) analysis is being done to group the factors. Findings Based on the study, it has been found that raw material usage, the shelf life of food, demand for the food and accuracy are dominant factors. MICMAC analysis indicated that number of driving, dependent and linkage factors are 6, 4 and 4, respectively. Research limitations/implications In the present study, 16 factors are being considered. In future, additional factors could be considered to deal with advancements in the food domain. Practical implications The study has been executed in discussion with practitioners in AM, and hence derived inferences have practical validity. Food making has become more agile with 3D printer and has become sensitive to customer demand. Social implications Social implications are primarily highlighted by the aspect of controlling the exact amount of nutrients corresponding to the application of food. In certain commercial applications, people can customize their shape and ingredients to be injected into the food. Originality/value The development of a model for the analysis of factors influencing AM in the food domain is the original contribution of the authors.

“…From the precision standpoint, however, their results are not on a par with repeated ink-jetting, which sprays the material directly from a nozzle. More specifically, it has been reported that if printing is performed using a new method that increases the filling density of a material and a method of preparing such a material under high pressure, a 3D structure can be materialized quickly using a material of high viscosity; this is also effective for nanomaterials [21] and food materials [22], which show substantial changes over time. However, this technology has a problem in that the size of the nozzle tip is too large to precisely fabricate a 3D shape on a nail.…”

Background:With the convergence of internet of things (IoT) and artificial intelligence (AI) technologies with three-dimensional (3D) printing or additive manufacturing, the applications have extended to beauty arts and cosmetics.Objective: The purpose of this research is to confirm the possibility of the convergence of IoT and AI 3D printing technology for cosmetics and beauty art for the 21st century.Methods: From January to October 2019, experienced 3D designers and customers were isolated, and more than 1,000 patterns were verified. Ultraviolet light-emitting diod (UV-LED) technology with built-in patented devices operating on a limited basis was used, and processes using low energies of 3 watts or less were applied. To control the 3D shape of the material, 3D printing technology with the z-axis at a height of 50 microns was applied to the shape to obtain a length of more than 3 cm. Completed products realized via custom design and manufacturing processes were delivered to the customers who installed them on their own. Results:More than 1,000 patterns were successfully printed through Wi-Fi from all over the world for AI-recommended nail art and tattoos. The stability of the IoT has confirmed the quality of 3D printed nails and two-dimensional (2D) tattoos. Moreover, customers are not exposed harmful environments associated with tattoos and 3D nail art. Conclusion:Application of 3D printing technology to the traditional nail art industry allows for the creation of sophisticated and customized shapes in a short period of time with a precision control of less than 50 microns in various colored 3D structures on artificial nail tips. This successful result of the convergence of AI and IoT 3D printing technology in the field of nail art and tattoos is expected to apply further to the fields of cosmetology, makeup, plastic surgery, and art.
