Document Type and Number:
Japanese Patent JP6517456
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing: an ink set for stereolithography which is for obtaining a stereolithographic article exhibiting excellent mechanical properties and excellent dimensional accuracy; a stereolithographic article formed using the ink set for stereolithography; and a method for producing the stereolithographic article using the ink set for stereolithography. An ink set for stereolithography according to the present invention is provided with a model material composition and a support material composition. The model material composition includes: monofunctional ethylenically unsaturated monomers (A) which have a Tg of 80˚C or higher, and which do not have urethane groups; polyfunctional ethylenically unsaturated monomers (B) which have a ring structure, have a Tg of 180˚C or higher, and do not have urethane groups; an oligomer (C); and a photopolymerization initiator (D). The support material composition includes: 20-50 parts by weight of water-soluble monofunctional ethylenically unsaturated monomers (a); 20-49 parts by weight of polyalkylene glycol (b) including AO groups and/or PO groups; 35 or fewer parts by weight of a water-soluble organic solvent (c); and a photopolymerization initiator (d).
