Nowadays, the functionally graded material (FGM) attracts attention in the material field. FGM is the material which can change a different function gradually. Therefore it is already applied to heat-resistant materials, high molecular materials and semiconductor materials and so on, which need multiple-functions. In this study, we tried to applying the ink-jet technology to forming the supreplastic-ceramic-film, due to the high precision and the grade control dispersion function. The measurement of the ability of the pigment ink-jet printer to make disperse, the preparation of ceramics ink and the adoption of materials as the specimen to be printed were carried out. As a result, it found that the smooth inclination distribution was applied by printing gradation pattern with the pigments-ink-jet printer. Moreover, it found that the ceramic-ink containing polyethylene glycol (PEG) 40wt% with pigments 10wt% the mixing was most stable. Although, the ink containing PEG 30wt% with pigments 10wt% suited the forming of a ceramic-film in present experiment.
