METHOD FOR MANUFACTURING SINTERED PRODUCT FROM THREE-DIMENSIONAL ADDITIVELY-MANUFACTURED ARTICLE, AND INKJET INK FOR 3D ADDITIVE MANUFACTURING USE
To appropriately manufacture a sintered product from a three-dimensional object, and provide a method for manufacturing a sintered product from a three-dimensional object as a solution, the method including a preparation step S11, a degreasing step S12, and a sintering step S13. In the preparation step S11, a multilayer made of an ink containing inorganic particles and an organic material is formed to prepare a three-dimensional object. The degreasing step S12 includes: a first degreasing step of heating the three-dimensional object under an inert gas atmosphere at a first average degreasing temperature for a first heating time to degrease the organic material; and a second degreasing step of heating the three-dimensional object degreased in the first degreasing step, under an inert gas atmosphere at a second average degreasing temperature higher than the first average degreasing temperature for a second heating time to degrease the organic material. In the sintering step S13, the three-dimensional object degreased in the second degreasing step is sintered at an average sintering temperature higher than the second average degreasing temperature to obtain a sintered product.
