光造形における造形モデルの精度向上

抄録

In order to reduce the time for product development, it is important to utilize the RP(rapid prototyping)technology. Among several methods in the RP technology,stereo lithography is the most prevailing and promising method since it provides the most accurate solid models. However, there is one area to be improved for the models which are produced using stereo lithography, the distortion or deformation which occurs on relatively thin parts of a model. To improve the model accuracy, quality engineerillg was applied and the optimal condition was obtained. As the generic function, "transformability" was employed, where the objective is to transform "shape" and "dimension" programmed in the CAD model as precisely as possible into a three dimensional solid object.
