| 摘要 |
A photocurable resin composition for three-dimensional printing which is visible-light curable is provided, comprising a photosensitive prepolymer in a range of 76.5 wt % to 96.8 wt %, a photoinitiator in a range of 0.01 wt % to 5 wt %, an auxiliary photoinitiator in a range of 0.01 wt % to 15 wt %, and a solvent in a range of 0.01 to 10 wt %. A three-dimensional printing system comprises: an accommodation unit, a lifting unit, a formation unit, and a control unit. The accommodation unit is for accommodating a printing material. The formation unit, which is connected to the lifting unit, can be driven by the lifting unit so as to move with respect to a light emission unit. The control unit, coupled to the lifting unit, controls motion of the lifting unit. The light emission unit may be a mobile electronic device, a display device, or a digital television. |
