Abstract
The present invention relates to a model material composition for shaping a model material by a material jetting optical shaping method, comprising a polymerizable compound, a photopolymerization initiator and a siloxane compound having one polymerizable group per molecule, the siloxane compound having a number average molecular weight of 300 to 10,000.
Claims16
A model material composition for shaping a model material by a material jetting optical shaping method, comprising a polymerizable compound, a photopolymerization initiator and a siloxane compound having one polymerizable group per molecule,
- wherein the siloxane compound has a number average molecular weight of 300 to 10,000,
- wherein the polymerizable group in the siloxane compound is a group selected from the group consisting of an acryloyl group, a methacryloyl group, a vinyl group, an allyl group and a vinyl ether group, and
- wherein the model material composition comprises the siloxane compound in an amount of 0.005 to 5% by mass, with respect to a total mass of the model material composition.
