Three Dimensional Printing (3Dp T>I) is an outstanding method for fabricating complex3D-shaped parts, that cannot be obtained by the conventional methods such as dry press, sheet stack, tape casting, and so on. In order to accomplish green part retrieval from ceramic powder-bed, it is indispensable to study redispersion technology. For the purpose, the effects of redispersion on Al,03, Si02, Ti02, and MR2 ceramic powder beds were investigated with specialreference to the molecular weight and concentration of various polyethylene glycol (PEG) as organic dispersants. Furthermore, redispersion phenomena were discussed in terms of chemical potential and osmotic pressure between powder bed and solvent. The experimental results were estimated with Flory-Huggins and van't Hoff theories. Under the appropriate redispersing conditions, it is emphasized that different types of electronics parts were obtained at the same time in one powder bed eventually.
