Conformal 3 D printing is a technique for manufacturing the conformal structure on the freedom surface of the bearing surface by means of 3 D printing. A conformal 3 D printing platform is established with the 3 D direct writing technology and the manipulator control technology with six-degrees freedom. This paper analyzes the structure of the data stream generated by the conformal 3 D print path on the curved surface,and discusses the generation method of the trajectory path. Tool path information on curve...
