Abstract

Being directed against the shortage of existing 3D printing, a five-axis 3D printer is designed, and a free form surface five-axis 3D printing method is presented. In this method, a five-axis 3D printer is used, a curved surface instead of a flat surface is used as the initial surface, each layer being printed is a curved surface rather than a plane. Three path planning methodologies are introduced according to different shape curved surface, contour line methodology, vertical cross section methodology and fixed parameter methodology. Then translational coordinates and rotating coordinates of the five-axis printer are calculated in term of some interpolation algorithm. The Non-uniform Rational B Spline (NURBS) technology is mainly used as the curved surface description method, and the fixed parameter path planning methodology is taken as an example to discuss the approach and algorithm of the free from surface five-axis printing method. The approach and algorithm include surface reverse engineering, path planning and coordinate computing etc.. The free form surface five-axis 3D printing method can avoid the step effects which always take place in existing 3D printing. The method is effective for the printing in which the bottom of the workpiece being printed is a sphericity or other curved surface shape or in which the main purpose is to cover a or many printing material layer on the underprop's surface. This method also can be used to spray some material on a curved surface.
