Abstract
The present invention provides a new and improved method of forming a turbine engine component having a plurality of airfoils disposed in an annular array between inner and outer shroud rings. The method includes forming inner and outer shroud ring patterns. The inner and outer shroud ring patterns may advantageously be formed by solid freeform fabrication techniques, such as stereolithography. An assembly fixture may be utilized to position the inner and outer shroud rings and an array of airfoils in a coaxial relationship. When the inner and outer shroud rings are to be assembled, axially inner and outer shroud ring patterns may be interconnected by providing relative rotation between annular sections of the shroud ring patterns. In addition, adhesive may be utilized to interconnect the sections of the shroud ring patterns.
