A manufacturing method of a gradient color slurry. The manufacturing method includes a plurality of coloring materials, wherein the coloring materials have a plurality of color depths. Providing a composite material, the coloring materials are mixed with the composite material and coloring thereof. The colored composite material is made up into a plurality of water-soluble slurries having the color depths. The water-soluble slurries are filled into a container in the order of the color depths thereof. Heating the container and keeping the temperature therein, so as to disperse the water-soluble slurries to form the gradient color slurry. In addition, a molding method of a three dimensional object is also provided.一種漸層漿料的製作方法。製作方法包括提供多個染色材料，其中染色材料具有多個色階。提供一複合材料，並且染色材料分別與複合材料相互混合並染色。將經染色的複合材料分別配製成具有所述色階的多個水溶性漿料。將水溶性漿料分別依所述色階的深淺依序充填至容器中。對該容器進行加熱，並於加熱後保持容器中的溫度，以使水溶性漿料產生擴散反應而形成漸層漿料。此外，一種三維實體的成型方法亦被提及。
