Ortho model resin is special dental resin material. The orthodontic models' surface are smooth, with high detail reproduction and high molding accuracy. With high surface hardness (>83D), ortho model resin is suitable for 3D printing high temperature resistant dental models(such as orthodontic models). With high-temperature resistance, the model printed by dental resin can withstand the high-pressure impact of the hot press molding instrument, and the deformation volume is small under high-temperature conditions.
