Abstract: The present application provides eight methods for improving the fineness of a specified region on the surface of a light-curable 3D printed model. In Methods 1-4, an anti-aliasing function is turned on/an image edge blurring function may be turned on entirely for a puppet 3D model, which can make the overall surface of the printed model smooth and flat. In addition, a specified region on the model surface may be circled, and an image sharpening function is turned on/the anti-aliasing function is turned off/the image edge blurring function is turned off to retain a marginal sawtooth effect of the sliced image in the specified region, so that specific feature lines of the printed model surface are obviously prominent, and the fineness of the specific features in the specified region of the model surface can be improved.
