         5 . A photocuring 3D printer, comprising:
 a resin tank according  claim 1 , and a light source provided outside the optically-transmissive wall.   
     
     
         6 . The photocuring 3D printer according to  claim 5 , wherein the photocuring 3D printer further comprises a LCD display unit having a same area as the optically-transmissive wall and covered at an outer side or an inner side of the optically-transmissive wall. 
     
     
         7 . The photocuring 3D printer according to  claim 6 , wherein the light source is a light array. 
     
     
         8 . The photocuring 3D printer according to  claim 7 , wherein a size of the light array is no larger than 120 inches. 
     
     
         9 . The photocuring 3D printer according to  claim 7 , further comprising a control unit configured to control lights in a selected area of the light array to be switched on or off 
     
     
         10 . The photocuring 3D printer according to  claim 5 , wherein the photocuring 3D printer further comprises a liquid photosensitive resin supplying device which is in communication with the tank body of the resin tank and is configured to supplement the liquid photosensitive resin into the tank body. 
     
     
         11 . A photocuring 3D printer, comprising:
 a resin tank according to  claim 2 , and a light source provided outside the optically-transmissive wall.   
     
     
         12 . The photocuring 3D printer according to  claim 11 , wherein the photocuring 3D printer further comprises a LCD display unit having a same area as the optically-transmissive wall and covered at an outer side or an inner side of the optically-transmissive wall. 
     
     
         13 . The photocuring 3D printer according to  claim 12 , wherein the light source is a light array. 
     
     
         14 . The photocuring 3D printer according to  claim 13 , wherein a size of the light array is no larger than 120 inches. 
     
     
         15 . The photocuring 3D printer according to  claim 13 , further comprising a control unit configured to control lights in a selected area of the light array to be switched on or off. 
     
     
         16 . The photocuring 3D printer according to  claim 11 , wherein the photocuring 3D printer further comprises a liquid photosensitive resin supplying device which is in communication with the tank body of the resin tank and is configured to supplement the liquid photosensitive resin into the tank body. 
     
     
         17 . A photocuring 3D printer, comprising:
 a resin tank according to  claim 3 , and a light source provided outside the optically-transmissive wall.
