| The research is based on a type of low-cost Desktop Rapid Prototyping System which replaces the laser with common UV light.In StereoLithography process, once the cross-section contours is obtained through the slicing processing on STL model, it is needed to do more data processing such as inside and outside boundaries recognition, facula radius compensation, scanning and path planning to generate process control data. Based on the summarization of former research, some advanced or new algorithms on data processing are provided in this paper. The subarea path planning rules and algorithm is studied in detail. And the solidification shrinkage compensation of curable resin is discussed as well. The article also presents the design theory and implement of molding process control, simulation and machine -time estimation.Finally, the control software with above functions is developed. Many prototypes of good quality have been produced by experiments on the Desktop Rapid Prototyping System, which indicates the software runs stably and reliably. |
