Abstract: At present,the main data interface file formats is:STL,IGES,STEP,etc.STL document has become standard format of a rapid prototyping manufacturing.The Pro/E 5.0 was taken to model the scaled track as an example and convert the part file to STL file.Setting different values of the height (A),angle control (B),step size (C),conducting orthogonal test to analyze the effects of them on the molding efficiency and molding quality.Finally the important order of the effect on the efficiency was obtained as C,B,A,and the optimal combination is C₂B₃A₁.The important order of the effect on the quality was obtained as C,A,B,and the optimal combination was C₁A₁B₃.The final validation test was conducted by the Fused Deposition Molding (FDM) 3D printer.The results showed that the obtained combinations were conducive to the better quality and efficiency.
