Abstract:
A method of fabricating an airfoil includes imaging a second end of the body portion to obtain image data, casting the tip portion utilizing the image data of the second end of the body portion and coupling a first end of the tip portion to the second end of the body portion. One or more features of the tip portion align with one or more features of the body portion. The method also includes additively manufacturing a core of the tip portion utilizing the image data and forming a casting mold about the core. The tip portion is cast in the casting mold. The coupling of the tip portion to the body portion including depositing a bonding material on a first end of the tip portion. An airfoil formed by the method is also disclosed.
