In this study, the effect of the laser beam irradiation method on the deformation characteristics of laser forming for plastic material by YAG laser was experimentally investigated. In the case of area irradiation method, bending angle becomes smaller after the irradiation, since the amount of bending-down is large during the irradiation. Therefore, even if the number of laser beam irradiation increases, large bending angle can not be obtained. On the other hand, in the case of scan irradiation method, the bending angle becomes larger after the irradiation, since the amount of bending-down is small during the irradiation. As a result, the scan irradiation method makes it possible to obtain large bending angles up to 90 degrees by increasing the number of laser scan. Therefore, in order to obtain larger bending angles, the scan irradiation method is more effective than the area irradiation method.
