When the temperature of the liquid resin in the inner layer tank body 31 meets the printing requirement, namely the temperature of the liquid resin in the inner layer tank body 31 is equal to the preset temperature, the photocuring 3D printer can start to print, namely the photocuring 3D printer forms to-be-printed layers, and the to-be-printed layers are solidified. Further, the two-layer resin liquid tank 30 further includes: and when the temperature sensor 32 detects that the temperature of the liquid resin in the inner-layer groove body 31 is higher than a preset temperature, the alarm device gives an alarm and can send out signals such as sound and light to give an alarm.
