Document Type and Number:
Japanese Patent JP7318803
Kind Code:
B2
Abstract:
A three-dimensional object producing method including applying an object forming liquid to powder including a base material and an organic material to form a solidified product, and removing the powder, which is deposited on the solidified product, from the solidified product using a powder removal liquid including an organic solvent. The following formulae are satisfied REDvalueofanon−formingpart<1.20REDvalueofaformingpart>0.55 The forming part is a portion of the powder to which the object forming liquid is applied, and the RED value of the forming part is a distance between HSP values of the forming part and HSP values of the organic solvent, and the non-forming part is a portion of the powder to which the object forming liquid is not applied, and the RED value of the non-forming part is a distance between HSP values of the non-forming part and the HSP values of the organic solvent.
