[57] [Abstract] [Problem] Excellent in transparency and heat resistance, excellent in mechanical properties, particularly excellent in toughness such as impact resistance and bending resistance, high in dimensional accuracy, Provided is a photocurable liquid resin composition having a low viscosity and excellent curability, capable of forming a three-dimensional object having little change over time in mechanical properties and shape. An aliphatic cyclic ether compound such as (A) bis (3,4-epoxycyclohexylmethyl) adipate, (B) pentaerythritol triacrylate, An acryloyl group-containing compound such as dipentaerythritol hexaacrylate, (C) a polyether polyol having three or more hydroxyl groups in one molecule, (D) a core structure of butadiene rubber and a shell structure of methyl methacrylate resin. Particles having a specific particle size, (E) a cationic photopolymerization initiator, and (F) a radical photopolymerization initiator. |
