PROBLEM TO BE SOLVED: To provide a set of a three-dimensional model and a storage member which include the three-dimensional model having excellent adhesion capable of closely adhering to a body surface portion of a patient without gaps and a fluid having an excellent shape-maintaining property of the three-dimensional model capable of stably maintaining a molded shape.SOLUTION: A set of a three-dimensional model 11 and a fluid 12 consist of the three-dimensional model 11 and the fluid 12 covering at least a part of the three-dimensional model 11. A specific gravity of the fluid 12 is 0.75 to 1.25 times the three-dimensional model 11. It is preferable that a polymer is further provided between the three-dimensional model 11 and the fluid 12. It is preferable that the three-dimensional model 11 floats on the fluid 12, and a hardness of the three-dimensional model 11 is 60 or less. It is more preferable that a water vapor permeability of the polymer is 1,000 [g/(m2 day)] or less. A method for storing the three-dimensional model 11 is to cover at least a part of the three-dimensional model 11 with the fluid 12.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】患者の体表面部に隙間なく密着できる密着性に優れる立体造形物と、成型形状を安定して維持することのできる立体造形物の形状保持性に優れる流動体とを有する立体造形物と保管用部材のセットの提供。【解決手段】立体造形物11と、立体造形物11の少なくとも一部を覆う流動体12と、を有する立体造形物11と流動体12のセットである。流動体12の比重が、立体造形物11に対して0.75~1.25倍である。立体造形物11と流動体12との間にポリマーを更に有する態様が好ましく、立体造形物11が、流動体12に浮遊した状態、立体造形物11の硬度が、60以下であることが好ましい。前記ポリマーの水蒸気透過度が、1,000[g/(m2・day)]以下であることがより好ましい。立体造形物11の少なくとも一部を流動体12により覆う立体造形物11の保管方法。【選択図】図1
