摘　　要：探讨了选择性激光烧结3D打印技术在开发发动机缸盖型芯方面的应用,总结概括了选择性激光烧结3D打印技术在开发型芯过程中出现的问题,并针对这些问题提出了解决措施和改进方案,主要包括新旧覆膜砂的合理的质量配比、工艺参数的合理设置、最佳的后处理工艺和支撑结构的设计和添加,最后通过改进措施打印出了强度、尺寸精度和表面品质满足使用要求的缸盖内部型芯。The application of SLS 3D printing technology was discussed in engine cylinder head sand cores, and the problems of 3D printing in the process of sand cores were also summarized. Some measures were taken to solve the problems in printing process, including the rational distributing proportion in old and new coated sand, the rational process parameters and the best post-treatment process and supporting structure. The results show that, using these measures, the engine cylinder head sand cores can be successfully printed with qualified strength, precision and surface quality.
