PURPOSE: To shorten a shaping time while enhancing the molding accuracy of a model. CONSTITUTION: A laser beam irradiation point is scanned at a high speed to be allowed to reach an auxiliary point 24a and scanned at a plotting speed from the auxiliary point 24a. When the angle formed by two sides formed by three points of continuous contour line data is near 180 deg., data at a central position is eliminated from scanning data. By this constitution, the high speed scanning of laser beam becomes possible without damaging the quality of a shaping model and, since useless data is eliminated, the quality of the shaping model can be also enhanced along with an increase in speed. |
