US 11,692,093 B2 · Resin composition, method for producing three-dimensional molding using same, and three-dimensional molding

Abstract

Provided is a resin composition from which a three-dimensional molding can be produced at an appropriate speed and with high dimensional accuracy, wherein the obtained three-dimensional molding has high strength. This resin composition is used in a method for producing a three-dimensional molding composed of a cured product of a liquid resin composition by selectively irradiating the liquid resin composition with active energy rays. The resin composition includes at least: a first polymerizable compound, in a liquid state at room temperature, having radical polymerizability; a second polymerizable compound, in a liquid state at room temperature, having no radical polymerizability; and a filler, wherein the surface of the filler is covered with the second polymerizable compound.
