摘　　要：在铸造领域,使用覆膜砂铸造已经成为一种主流的铸造方法,它采用原砂与酚醛树脂混合,通过添加固化剂和润滑剂,然后对其加热最终得到砂型(芯)的方法。将快速成型技术与传统铸造技术相结合,不但提升了零件的制造效率,还可以制造一些复杂零件。本文以覆膜砂的激光烧结为例,介绍快速成型在铸造复杂零件方面的应用。In the field of casting, using coated sand has become a mainstream of casting method, which uses the method of original sand mixed with phenolic resin added curing agent and lubricant, then heats it to obtain sand mold（core）.Combining rapid prototyping technology with traditional casting technology can improve the efficiency of manufacturing parts, and also can make some complex parts. In this paper, the application of rapid prototyping technology in manufacturing complicated parts was introduced by using case of laser sintering on coated sand.
