N2 - Assembly Mold SDM (Shape Deposition Manufacturing) has been used in combination with Gel Casting to fabricate ceramic micro gas turbine components. Full 3-dimensional ceramic turbines and compressors with a feature size down to 200 μm were built. The turbine has been tested and been spun up to 456,000 rpm. During the research, it was found that the development of a ceramic air bearing is desirable. Thus, a process utilizing MEMS techniques has been developed to fabricate patterns with 125 μm feature size. In this paper, the techniques used to fabricate functional rotor groups, improve accuracy, and pattern micro features will be discussed.
