Claim 0:
1. A method of printing a three-dimensional article comprising:
selectively depositing layers of an ink in a fluid state onto a substrate to form the three-dimensional article,
wherein the ink comprises:
20-60 wt. % oligomeric curable material;
15-50 wt. % cyclocarbonate (meth)acrylate monomer; and
0.1-5 wt. % photoinitiator, based on the total weight of the ink,
wherein the oligomeric curable material comprises one or more ethylenically unsaturated species having a weight average molecular weight of 500-6,000;
wherein the cyclocarbonate (meth)acrylate monomer has the structure of Formula (A1):, wherein R1 is selected from the group consisting of a linear or branched C1-C4 alkylene moiety;
R2 is H or CH3; and
wherein the ink, when cured, exhibits a tear strength of 30 to 200 kN/m when measured according to ASTM D624.
