Abstract: To provide a dental stereolithography-type three-dimensional printing material in which the total preparing time required from modeling with using a 3D printer to a final curing is short, work efficiency is excellent, temporal shrinkage deformation of a dental three-dimensional modeled object is suppressed and a dimensional accuracy is excellent. The dental stereolithography-type three-dimensional printing material of the present invention comprises at least one or more (a) monofunctional acrylate monomer having an aromatic ring and (b) photopolymerization initiator, wherein an electronegativity difference between adjacent atoms which are bonded by covalent bond in all atoms constituting the (a) monofunctional acrylate monomer having an aromatic ring is less than 1.0.
