Abstract：
A rapid prototyping method for aeroengine blade was presented based on the additive manufacturing characteristics. The relationship between the forming parameters and the craft quality was established by analyzing the pre-treatment of the 3D model, the rapid prototyping and the post-processing of the forming parts. Meanwhile, the optimization schemes at each stage of this process was put forward on the forming mechanism of jet wire. The results show that the method can prepare products with a precision of IT8 and surface roughness below 3 μm in only 1/5 cycles of conventional materials reduction process. Therefore, the research of this technology lays a theoretical foundation for the rapid manufacturing of complex shaped products.
