Abstract
This Phase I SBIR project will develop a tool-less direct core fabrication technology based on ceramic stereolithography. The technology will eliminate the high cost and long lead time associated with injection molding tooling and will reduce prototyping costs for advanced cored airfoils by > 50%. The rapid prototyping process will allow parallel exploration of various core designs, which will accelerate the development of higher performance airfoils and turbine engines. The Phase I effort will build on previous related development at TA&T and by our collaborators. Phase I will entail material property evaluation to ensure compatibility with the casting process, fabrication of advanced core designs and assessment of surface roughness and dimensional accuracy. Phase I will culminate with a casting demonstration using cores fabricated by the new process.
