Abstract

Due to a recent epidemic of COVID 19, the possibility of 3D tattoo printing technology using the Internet of Things (IoT) control system developed in a non-face-to-face contact process was identified. A non-surgical tattoo process and hygiene safety differentiated with silver tattoo ink was used to solve the health problems arising from the surgical tattoo process and to identify 3D tattoo printing techniques through a non-personal contact concept. During the tattoo processing, the image selected by the customer is sent to a designated printer via an IoT control system in a separate location. A piston-type extruder (PTE) printing technique was used with a 100-micrometer nozzle tip. The tattoo ink was printed on a hydrophobic or hydrophilic substrate, and then tightly contacted to a stratum corneum composed mainly of keratin and lipids. Based on the thickness of the stratum corneum diffused from the surface according to the replacement cycle of 2 weeks, it was confirmed by the tattoo ink concentration and contact time that the printed tattoo disappeared within 3 days to 2 weeks. The silver tattoo ink disappears entirely in two weeks after it has been elaborately transferred to the stratum corneum of the human skin or nails in a web-based, non-face-to-face contact printing process. Repeated testing has proven that painless attachment to prints and sterile surfaces is an active process to control the quality of non-permanent tattoos. IoT enabled tattoo printing technology developed from the non-face-to-face contact concept includes the following steps: 1) Preparation of silver tattoo ink; 2) Accurate dispensing control of 3D printed materials; 3) Unique and fast design; 4) Convergence of web-based control to prevent the transmission of infectious diseases and protect personal information.
