Photocurable support material composition for inkjet 3D printer, ink for inkjet 3D printer, cartridge for inkjet 3D printer, manufacturing method of support material, and manufacturing method of stereolithography product
PROBLEM TO BE SOLVED: To provide a photocurable support material composition for an inkjet 3D printer having excellent solubility in a solvent and sufficient hardness of a cured product after curing. A photocurable support material composition for inkjet 3D modeling according to the present invention contains a water-soluble ethylenically unsaturated monomer containing an ionic group and a counterion, and a photopolymerization initiator. There is. The ionic group is preferably at least one selected from the group consisting of a carboxylic acid group, a phosphoric acid group, and a sulfonic acid group. The counterion is preferably at least one selected from the group consisting of sodium ion, potassium ion, and ammonium ion. [Selection diagram] None
