Abstract
A method and apparatus for printing an electric circuit directly on a target surface having a three-dimensional shape are provided. In this method, a 3D printing apparatus that can be attached to a target surface is used. In this printing method, two-dimensional information about the shape of the electric circuit to be printed and information about the three-dimensional shape of the target surface are input. Two-dimensional information about the shape of the electric circuit to be printed is adjusted based on the information about the three-dimensional shape of the target surface to generate three-dimensional information about the electric circuit to be printed. Based on this, a tool path for controlling the 3D printing apparatus is generated.An electric circuit can be directly fabricated on a target surface having a three-dimensional shape by the method and apparatus. In addition, an electronic device having a three-dimensional electric circuit manufactured by the present method can be applied in various ways.
