【Abstract】 Based on the electrostatic deflection spraying, the rapid prototyping (RP)is to form layered sections and make the prototype or part layer-by-layer by the deflection spraying of electrically charged powder granules passing through the electrostatic field.A numerical simulation system was developed for the electrostatic deflection spraying based RP process. The system can plan the process,generate and display the scanning path and simulate the forming process of the solid prototype or part according to the CLI format section data, which provides fundamentals and guidelines for the experimental exploration of the new rapid prototyping process.更多还原
