Summary: | PROBLEM TO BE SOLVED: To provide a method of manufacturing a shaping particle suited for a structure of a support part easily removable by a water-containing liquid and capable of suppressing deterioration of shape accuracy of a three-dimensional object.SOLUTION: The present invention relates to a method of manufacturing a shaping particle 5, the method comprising in the order of description: a mixing step for mixing a powder containing a first particle 1 containing a water-soluble material and a powder containing a second particle 2 containing a material less soluble in water than the water-soluble material contained in the first particle 1 to obtain a mixed powder; a drying step for drying until the water content of the mixed powder becomes less than 1.0 mass%; and a compositing step for compositing the first particle 1 and the second particle 2 to form a shell 4, which contains the largest amount of the material less soluble in water than the water-soluble material, on the surface of the first particle 1.SELECTED DRAWING: Figure 1
【課題】水を含む液体によって容易に除去することができるサポート部の構成に好適な、立体物の形状精度の低下を抑制できる造形粒子の製造方法を提供する。【解決手段】水溶性材料を含有する第1の粒子1を含有する粉体と、第1の粒子1が含有する水溶性材料よりも水に対する溶解度が小さい材料を含有する第2の粒子2を含有する粉体と、を混合して混合粉体を得る混合工程と、前記混合粉体の含有水分量が1.0質量%未満となるまで乾燥する乾燥工程と、第1の粒子1と前記第2の粒子2を複合化し、水溶性材料よりも水に対する溶解度が小さい材料を最も多く含有するシェル4を、第1の粒子1の表面に形成する複合化工程と、を、この順で有する造形粒子5の製造方法。【選択図】 図1 |
