摘要： Provided is a three-dimensional object producing method that includes applying an object forming liquid to powder including a base material and an organic material to form a solidified product, and removing the powder deposited on the solidified product from the solidified product using a powder removal liquid including an organic solvent. The following formulae are satisfied RED of non-forming part 0.55. The forming part is a portion of the powder to which the object forming liquid is applied and RED of the forming part is a distance between HSP of the forming part and HSP of the organic solvent. The non-forming part is a portion of the powder to which the object forming liquid is not applied and RED of the non-forming part is a distance between HSP of the non-forming part and HSP of the organic solvent.
