【Abstract】 In the process of Selective Laser Sintering, layers of material are successively cured by laser until the model′s final shap e is obtained. A large number of vector scanning must be carried out in the grow th process which is from 2D to 3D, reasonable scanning paths can increase the pr oductivity and improve the working status of the scanner. In this paper, a laser scanning path generating algorithm is proposed , which is well used in our SLS machine .更多还原
