MODEL MATERIAL FOR FORMING OPTICALLY SHAPED ARTICLE, SUPPORT MATERIAL FOR SUPPORTING SHAPE DURING OPTICAL SHAPING OF OPTICALLY SHAPED ARTICLE, AND METHOD FOR MANUFACTURING OPTICALLY SHAPED ARTICLE IN INKJET OPTICALLY SHAPING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a model material showing very little swell or moisture absorption deformation due to water or moisture absorption during optical curing and after curing and used for forming an optically shaped article in an inkjet optically shaping method, and to provide a support material or the like which shows excellent water solubility of an optically cured substance, which can be easily removed after optical shaping and used for supporting the shape during optical shaping of the optically shaped article in the inkjet optically shaping method.;SOLUTION: The model material for forming the optically shaped article in the inkjet optically shaping method contains a curable resin component having a weighted average value of SP values of 9.0 to 10.3. The support material for supporting the shape during optical shaping of the optically shaped article in the inkjet optically shaping method contains a water-soluble mono-functional ethylenic unsaturated monomer (F), polyoxypropylene glycol having number average molecular weight of 100-5,000 and/or water (G), and a photopolymerization initiator (D).;COPYRIGHT: (C)2012,JPO&INPIT
