英文摘要:
      The key role of superalloy in aviation engine parts, and the application background of ceramic casting core were introduced. The research status and significance of molding technologies of ceramic core were summarized. The progress in investigation on advanced molding technologies of ceramic core, including freeze-casting, solid free-forming fabrication, negative replica method and core packing slip casting was systematically reviewed in this paper. The paper focused on solid free-forming fabrication technology in respect of stereo lithography and three dimensional printing. The remarkable advantages of solid free-forming fabrication, and the challenges of industrialization of ceramic core with solid free-forming fabrication were finally discussed.
