ABSTRACT: In this Phase I SBIR project TA & T will use ceramic stereolithography to fabricate engineered molds for investment cast turbine airfoils with the goals of reduced dimensional and metallurgical variability, finer cast features, and improved yield. The application target will be advanced high pressure turbine (HPT) airfoils cast in single crystal superalloys, the most difficult to fabricate and the highest value components in a turbine engine. The Phase I work will involve mold design, casting process modeling, mold fabrication, casting and characterization. BENEFIT: CSL reduces the number of process steps to get to metal from 12 to 3 and eliminates two tool sets (wax and ceramic). The primary commercial application is civilian aircraft that use turbine engines.
