熔模铸造生产新型汽轮机叶片需要反复试验验证,设计周期长,成本较高。采用熔融沉积技术得到ABS材料的叶片模样,粘接常规蜡质制作的浇注系统,经过挂砂、脱蜡、脱ABS,浇注冷却后获得了合乎要求的汽轮机叶片。验证了由FDM技术打印制作的ABS材料熔模用于叶片熔模铸造的可行性。 Investment casting production of new turbine blades require repeated testing and validation, long design cycle, higher cost. The melting and deposition technology was used to obtain the leaf pattern of ABS material and the conventional waxy casting system was bonded. After satisfying the requirements of steam turbine blade through hanging sand, dewaxing, removing ABS and pouring cooling, The feasibility of using ABS material printed by FDM technology to simulate blade investment casting was verified.
