摘　　要：以设计制造金属艺术品鼎为例,将选区激光烧结快速原型技术应用到艺术铸造领域,具有把复杂的艺术品铸件CAD模型直接转化为实体原形的熔模型的特点,实现了金属艺术品无模快速制造,总体精度为100±0.15mm;特别在针对古代青铜器的精确复制方面,解决了传统艺术铸造的金属工艺品产生尺寸收缩的问题。Regarding designing and making the pot of metal artwork as example, the paper applies selective laser sinter fast prototype technology to art casting field, which has characteristic of turning CAD model of the complicated artwork castings into investment casting pattern of entity prototype directly, and realizes no mould fast manufacture of metal artwork. Its overall precision is 100：1：0.15 mm, Especially, in duplicating accurately to the ancient bronze ware, it has solved the problem that the size of metal artwork of traditional art casting is easy to shrink.
