Artificial nail and production equipment employing 3D printing technique for UV LED curing

A method of producing an artificial nail, the method comprising:

• automatically recognizing nail information of a user through a 3D scanner (S100);
• recognizing a 2D or 3D nail decoration design through a UV 3D printer (S200);
• forming, by the UV 3D printer including a device which is capable of adjusting a Z-axis, a decoration layer according to a curved surface of a nail form of the user by using the nail decoration design recognized in operation S200, on the basis of the nail information of the user recognized in operation S100 (S300);
• forming, by the UV 3D printer, an adhesive layer on a lower portion of the decoration layer produced in operation S300 (S400);
• and
• completely hardening the formed decoration layer and adhesive layer in a short time by performing a heat treatment on the formed decoration layer and adhesive layer through a UV lamp of the UV 3D printer (S500),
• wherein the device is equipped within the UV 3D printer and is capable of adjusting the Z-axis, the device comprising:
• a nail tip support, a lower plate, and a rack for supporting the nail tip support which are integrally coupled;
• a rack gear guide for protecting the rack, wherein the rack is embedded within the rack gear guide;
• a stepper motor and a motor bracket holding up the stepper motor which are integrally coupled to be fixed on the lower plate;
• and
• a pinion connected with the stepper motor through a rotation shaft to rotate the pinion, wherein the rack and the pinion are installed while being engaged with each other and the pinion rotates and the rack vertically moves to make the nail tip support vertically move,
• wherein the device is for producing the decoration layer with multiple layers to form the artificial nail having a 3D shape,
• wherein an ink ingredient of the UV 3D printer contains a solution, in which oily TiO2, oily polymer, aqueous vitamin and aqueous collagen are mixed, and
• wherein the adhesive layer contains an oily polycaprolactone (PCL) ingredient aqueous vitamin and aqueous collagen ingredients.
