Method for producing sintered product from three-dimensional molded article, and inkjet ink for 3D molding
The technical problem to be solved by the present invention is to appropriately produce a sintered product from a three-dimensional molded article, the method for producing a sintered product from a three-dimensional molded article as a solution comprising a preparation step (S11), a degreasing step (S12), and a sintering step (S13). In the preparation step S11, an ink containing inorganic particles and an organic material is laminated to prepare a three-dimensional molded article. The degreasing step (S12) includes: a first degreasing step for degreasing the organic material by continuously heating the three-dimensional molded article at a first average degreasing temperature for a first heating time in an inert gas atmosphere; and a second degreasing step for degreasing the organic material by continuously heating the three-dimensional molded article degreased in the first degreasing step for a second heating time at a second average degreasing temperature higher than the first average degreasing temperature in an inert gas atmosphere. In the sintering step (S13), the three-dimensional molded article 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.
本发明要解决的技术问题是由三维成型物恰当地制造烧结产品，作为解决方案的、由三维成型物制造烧结产品的方法包含：准备工序S11、脱脂工序S12和烧结工序S13。准备工序S11中，将含有无机颗粒和有机材料的墨层叠而准备三维成型物。脱脂工序S12包含：第一脱脂工序，在非活性气体气氛下，以第一平均脱脂温度对三维成型物持续加热第一加热时间，对有机材料进行脱脂；第二脱脂工序，在非活性气体气氛下，以高于第一平均脱脂温度的第二平均脱脂温度对经第一脱脂工序脱脂后的三维成型物持续加热第二加热时间，对有机材料进行脱脂。烧结工序S13中，以高于第二平均脱脂温度的平均烧结温度对经第二脱脂工序脱脂后的三维成型物进行烧结，得到烧结产品。
