| 摘 要： | 与点扫描方式相比，面曝光选区激光熔化因具有成形效率高、残余应力水平低等优势，而成为极具发展前景的新一代选区激光熔化增材制造技术的发展方向。利用波长为915 nm的二极管连续激光器作为光源，结合电寻址反射式纯相位液晶空间光调制器，搭建了新一代面曝光选区激光熔化增材制造原理装置平台。获得了“○”形样式的面光斑曝光，基于光敏纸和低熔点金属粉末材料进行面曝光熔化成形并获得了样品，实现了面曝光选区激光熔化的原理性实验验证。

| Abstract: | 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. |
