Document Type and Number:
WIPO Patent Application WO/2018/143299
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an ink set for stereolithography which is for obtaining a stereolithographic article exhibiting 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: a radically polymerizable compound (A); a cationically polymerizable compound (B); a radical polymerization initiator (C); and a cationic polymerization 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 oxyethylene groups and/or oxypropylene groups; 35 or fewer parts by weight of a water-soluble organic solvent (c); and 1-20 parts by weight of a photopolymerization initiator (d).
