  • Compared with a point laser scanning method, a surface exposure laser melting has advantages of high forming efficiency and low residual stress, which has become a promising new generation selective laser melting of additive manufacturing technology. In this paper, a principle device platform of new generation surface exposure selective laser melting were developed with a light source of 915 nm diode laser, combined with an electrically addressed reflective pure phase liquid crystal spatial light modulator. Its principle experimental verification of surface exposure selective laser melting were implemented. A sample of surface exposure selective laser melting with a “○”-shaped pattern were obtained by using a low melting point metal powder.
